The brand new CIES Football Observatory Monthly Report compares 87 top divisions worldwide from the point of view of the number of yellow and red cards given by referees between 2015 and 2020. The study highlights great differences according to country and reveals the existence of significant correlations between the amount of cards per match and many socio-economic indicators for nations.

The number of cards varies considerably according to the confederation of belonging of the leagues studied. At one extreme, in South America (CONMEBOL), referees handed out on average 5.83 cards per match. This figure is 45% higher than that observed in the 15 Asian (AFC) leagues included in the study (4.00). Invariably, away teams receive more cards than home ones.

The gross domestic product (GDP) and the Human Development Index (HDI) are inversely correlated to the quantity of cards. This indicates that the matches played in nations whose inhabitants enjoy a higher standard of living and education are less fraught, or at least are less sanctioned by the referee corps.

A significant positive statistical correlation was also measured between the amount of cards and the homicide rate per country. The violence present in a society thus seems to be transposed to football. In addition, the more citizens consider that the level of corruption in their country is high, the more referees are likely to hand out cards. This result could reflect the existence of a social climate where distrust and suspicion are rife.

These findings show that football matches take place under different dynamics according to the social, economic, political and cultural context of the country in which they are played. They confirm the very strong link between football and society and reveal the importance of taking into account the specifics of countries for a fine analysis of the game even in a context of globalisation.

The 303rd edition of the CIES Football Observatory Weekly Post presents the big-5 league players whose transfer value would increase the most if their contract with the club of belonging was extended for an additional year. The most positive gap overall was recorded for Jadon Sancho (+€43M), ahead of Kylian Mbappé (+€39M) and Lionel Messi (+€35M).

With two years of contract remaining, the transfer value of Jadon Sancho according to the exclusive CIES Football Observatory algorithm is currently just above €180M. A one-year contract extension would drive this figure up to €223M. If Kylian Mbappé extended his contract with Paris St-Germain from June 2022 to June 2023, his estimated transfer value would increase from €242M to €281M.

Lionel Messi leads the table among players with only one year of contract remaining ahead of Georginio Wijnaldum and Ferran Torres. By renewing their contracts for an additional year, their transfer values would increase from about €80M to €115M for Messi, from €44M to €64M for Wijnaldum, as well as from €42M to €61M for Torres.

Issue number 302 of the CIES Football Observatory Weekly Post analyses the InStat data on ball movement in kilometres during possession phases by teams from 35 European competitions for the seasons 2018/19 and 2019/20 (2018 and 2019 for summer leagues). Bayern Munich (12.7 km per match) outranks Manchester City (12.5 km) and Liverpool (12.3 km).

Bayern Munich players achieve on average slightly fewer passes per game than those of Manchester City (705 versus 722), but their distance is longer (18.0 metres versus 17.3). Liverpool players only make 654 passes per match (9th position), but their length (18.8 meters) is much greater than that measured for the vast majority of teams in the top positions of the rankings.

The Greek side of Panionios is at the bottom of the table with a ball circulation distance of about 6.8 kilometres per game. Cardiff City is anti-penultimate with the lowest number of successful passes overall (326). The highest average passes lengths were recorded for two Scottish teams: Livingston (23.1 meters) and Hamilton Academical (22.4). Contact us to know more about InStat data and services.

The 56th edition of the CIES Football Observatory Monthly Report analyses the characteristics of the coaches at the head of 1,646 teams from 110 leagues in 79 countries worldwide. The study covers three aspects: the age, the length of stay in the club managed and the origin. The typical profile for a coach is a male just under 50 years of age (48.8) in charge for less than one year (301 days).

Altogether, 28.3% of coaches managing on the 1st of June 2020 the teams analysed grew up in another association than that of the club trained. This percentage is higher than that measured among players in the same competitions: 24.7%. The analysis also shows that almost two-thirds of coaches are former professional players: 64.3%. Defenders over-represented, while former goalkeepers are under-represented.

Issue number 301 of the CIES Football Observatory Weekly Post reveals that Argentina is the most represented nation among expatriate coaches. The 68 Argentinians present abroad on the 1st June 2020 were at work in 22 different countries. Most of them were active in other Latin American countries. Similar to players, their top destination was Chile (11 coaches). Spaniards are also well represented abroad (41 coaches in 21 countries), as well as Serbs (34 coaches in a record number of 24 countries).

The 300th edition of the CIES Football Observatory Weekly Post compares 35 European leagues according to the number of penalties per game whistled by referees since the 2017/18 season (2018 for summer leagues) as per data provided by our partners InStat. At the top of the table is the Polish Ekstraklasa (a penalty every 230 minutes), while at the opposite end is the Norwegian Eliteserien (every 389 minutes).

The Premier League (382’) and the Championship (377’) in England are the second and third leagues where the fewest penalties are whistled, which confirms the particular style of refereeing in the United Kingdom. This result can also be explained by the lower tendency of players to ‘look for fouls’. Penalties are also not whistled very often in the German Bundesliga (321’), while their frequency is much greater in the Italian Serie A (249’), the French Ligue 1 (262’) and the Spanish Liga (268’).

At club level, the Serbian side Crvena Zvezda leads the rankings with a penalty obtained every 209 minutes. Among big-5 league clubs, Lazio (296’) tops the table ahead of Paris St-Germain (319’) and Sampdoria (325’). Burnley FC is at the other end of the spectrum with only four penalties in 105 matches (every 2’362 minutes), ahead of Newcastle United (five penalties, of which only one scored) and the Norwegians of Odds BK.

The 299th edition of the Weekly Post presents the 100 big-5 league players with the highest estimated transfer values according to the CIES Football Observatory algorithm. Kylian Mbappé tops the list ahead of four Englishmen: Raheem Sterling, Jadon Sancho, Trent Alexander-Arnold and Marcus Rashford. The young Bayern Munich prodigy Alphonso Davies enters the top 10.

Despite the COVID-19 crisis, the estimated transfer value of Kylian Mbappé remains very high: €259.2 million. The French striker is still very young and his contract with Paris St-Germain only ends in 2023. With just one year of contract remaining and almost 33 years of age, Lionel Messi (€100.1 M) only ranks 21st. Cristiano Ronaldo (€62.8 M, 70th) is the oldest player in the top 100 list. In total, 22 big-5 league footballers have an estimated value of more than €100 million.

Alphonso Davies (9th, €133.5 M) is the youngest footballer in the top 20 ahead of Erling Haland (15th, €107.3 M). The most expensive players per position are Ederson Moraes (€86.8 M) for goalkeepers, Matthijs de Ligt (€104.7 M) for centre backs, Trent Alexander-Arnold (€171.1 M) for full backs, Frenkie de Jong (€102.1 M) for defensive midfielders, Bruno Fernandes (€104.9 M) for attacking midfielders and Kylian Mbappé (€259.2 M) for forwards.

The German Bundesliga was the first major European league to restart after the COVID-19 break. Issue number 298 of the CIES Football Observatory Weekly Post presents the players with the best statistics during current season for eight different indicators according to the data provided by our partners OptaPro.

Yann Sommer leads the table for the number of saves, Kingsley Ehizibue (Köln) did the most successful tackles, while Omar Mascarell (Schalke 04) and Jamilu Collins (Paderborn) made the most interceptions. Alphonso Davies (Bayern) heads the rankings for successful dribbles, Sven Bender (Bayer) for accurate passes, Christopher Nkunku (RB Leipzig) for assists having led to attempts and Robert Lewandowski (Bayern) for shots.

Union Berlin’s centre forward Sebastian Andersson won more than twice aerial duels than the second player who won the most: 210 compared to 102. This astonishing figure is related to the style of play of his team, which fields the tallest line-ups in Europe, as illustrated by the exclusive CIES Football Observatory Demographic Atlas.

Issue number 297 of the CIES Football Observatory Weekly Post analyses the employment of head coaches in 84 top divisions worldwide between January 2015 and December 2019. During this period, the average number of coaches per club in charge for at least three domestic league matches goes from 9.1 in Bolivia to 2.6 in Sweden. On average, a coach managed 40.6 games.

The data per league represent a fair estimate of the real ones as we only included in the sample the championships for which we could find the complete coaching history for at least half of the clubs concerned. The club rankings only include teams that have always been in the first division during the period considered.

The highest value was recorded for Club Real Potosí. The Bolivian side employed 20 different coaches for at least three domestic league matches between 2015 and 2019. On average, they were in charge for 11.3 games. Only 30 clubs out of the 766 taken into consideration employed a single coach during the five-year period studied. All current big-5 league teams had at least two coaches during this period.

Issue number 296 of the CIES Football Observatory Weekly Post reveals that Lincoln Red Imps from Gibraltar is the current top division team worldwide having won the highest percentage of domestic league matches played between 2015 and 2020 by three or more goals: 49.6%. AFC Ajax is fifth (37.4%), while Paris St-Germain and Barcelona are ninth (35.4%).

At league level, the highest percentage of easy wins was recorded in the top division of Macao (42.5% of total matches), ahead of Tahiti (38.1%) and Estonia (32.6%). The figures for the five major European leagues vary between 18.8% in Germany and 15.5% in Italy. The average for the 151 top divisions analysed is 14.4%.

The greatest percentage of fixtures ended in a tie between 2015 and 2020 was recorded in Gambia (42.1%), while the lowest was observed in Macao (14.9%). Naft Masjed Soleyman from Iran is the current top division team with the highest percentage of draws during the period surveyed (47.4%). Tukums from Latvia is at the opposite end of the table (8.2%).

The CIES Football Observatory just published its 55th Monthly Report. The study analyses the contribution of national associations worldwide from the point of view of the production of professional players. The sample includes 55,865 footballers having played during the 2019 calendar year in 132 top or second division leagues from 93 countries covering all continents.

To produce the ranking, domestic league minutes played by each footballer were weighted according to a coefficient of clubs’ sporting strength, calculated by taking into account the division and results of teams at national level, as well as the results of the representatives of every association in international club competitions. The origin of players was defined as the association where they grew up.

Brazil stands out as the world leader regarding the production of professional footballers. Brazilians are numerous (2,748 in the 132 leagues studied, of which 1,541 are abroad), play a considerable number of minutes (1,203 domestic league minutes per year compared to a general average of 1,133 minutes) and are active in high-level clubs (sporting coefficient of 0.49 compared to an average of 0.37).

France is the second world powerhouse, just ahead of Spain. The French are more numerous than the Spanish in the leagues studied (1,744 as opposed to 1,350), but are less fielded (on average 1,260 minutes against 1,360 in 2019) and play in clubs with a lower level (average sporting coefficient of 0.55 as opposed to 0.63). Argentina ranks fourth outranking two other European countries: England and Germany.

The 295th edition of the CIES Football Observatory Weekly Post ranks 150 top division leagues and clubs worldwide according to the percentage of goalless games during the five-year period between January 2015 and December 2019. At the top 30 places are 23 Africans domestic championships. The highest percentage overall was recorded in Gambia (23.5%) ahead of Cameroon (19.1%).

The highest and lowest percentages per Confederation were recorded for Iraq (14.9%) and Macao (2.9%) in Asia (continental average of 7.6%), Gambia (23.5%) and Madagascar (7.4%) in Africa (13.9%), Haiti (18.5%) and Suriname (3.0%) in North America (8.1%), Argentina (11.5%) and Bolivia (5.6%) in South America (8.3%), as well as Montenegro (13.0%) and Northern Ireland (3.4%) in Europe (7.9%).

At club level, the figures vary between 29.8% for Gambia Ports Authority (GPA) and 0.0% for Warrenpoint Town. None of the 167 games played by the Northern Irish team during the period considered ended goalless. The highest percentage for current teams from the five major European leagues was recorded for Angers (23 0-0 out of 191 matches, 12.0%), while the lowest was observed for Cagliari (6 out of 195, 3.1%).

Early professional experience is key to succeed in football. Great discrepancies exist between clubs and leagues in the opportunities given to young players to prove their talent. Issue number 294 of the CIES Football Observatory Weekly Post presents the percentage of minutes played in the current season or the last completed one by U21 footballers from 1,292 clubs and 93 top divisions worldwide.

At league level, the playing time of U21 footballers stretches from 29.0% in the Slovakian Super Liga to only 3.7% in the Saudi Pro League and the Turkish Süper Lig. In South America, the figures vary from 21.2% in Uruguay to 11.0% in the Argentina. The French Ligue 1 is the major European league with the highest percentage of minutes by U21 players (15.0%), while the Spanish Liga is at the opposite end of the table (7.0%).

The highest figures at club level per Confederation were recorded for the reserve team of Wellington Phoenix in New Zealand (93.3%), the Young Lions in Singapore (81.1%), University College Dublin in Ireland (78.0%), Cavalier in Jamaica (58.1%), Universidad San Martín in Peru (56.6%) and NA Hussein Dey in Algeria (40.0%). In the big-5, the highest value was measured for LOSC Lille (32.1%), while four clubs did not field U21 players (Levante, Crystal Palace, Union Berlin and Sheffield United).

Between January 2015 and December 2019, Red Star Belgrade won 130 domestic league matches out of the 135 during which they scored the first goal: 96.3%. This is the highest value measured among clubs from 92 top divisions worldwide ahead of Sherif Tiraspol from Moldova (94.1%) and Albirex Niigata Singapore (93.3%). The full analysis is available in the 293rd CIES Football Observatory Weekly Post.

The highest percentages of wins in case of first goal for current big-5 league teams over the five years studied were recorded for Paris St-Germain (89.9%, 124 wins out of 138), Barcelona (88.5%, 116 out of 131) and Manchester City (87.1%, 115 out of 132). Per league, the lowest value were recorded for Toulouse, Augsburg, Udinese, Eibar and Southampton. The lowest percentage overall was recorded for the Australian side Central Coast Mariners (20 wins out of 53, 38%).

At league level, the values range from four fifth of wins for the team having scored the first goal in the Moldavian top division to only about two thirds in the Chilean one. The average for the 92 competitions analysed is just below 70%. At the level of the big-5, the percentages go from 71.1% in the English Premier League to 67.8% in the German Bundesliga. The lowest values in Europe were recorded for the Belgian and Norwegian top divisions (66.3% in both cases).

Issue number 292 of the CIES Football Observatory Weekly Post ranks countries worldwide according to the number of their representatives having played professional football abroad during the calendar year 2019. Brazil is at the top of the table (1,600 players, of which 74.6% active in top division leagues) ahead of France (1,027, 74.0%) and Argentina (972, 75.5%).

In total, 186 national associations had at least one player expatriated in the 141 leagues from 93 countries included in the sample. However, altogether, Brazil, France and Argentina provided up to almost one quarter of the total foreign workforce in global football (22.5%). Nigeria is the main African exporting nation (399 players abroad), while Japan is the principal Asian one (161).

The CIES Football Observatory Atlas of Migration presents the main destinations for each origin. This exclusive tool notably reveals that Portugal is by far the main destination for Brazilians, ahead of Italy and Japan. The three main destinations for the French expatriates are England, Belgium and Luxembourg, while those of the Argentineans are Chile, Mexico and Spain.

The 291st Weekly Post of the CIES Football Observatory highlights the main clubs from where current big-5 league players departed to reach the five major European leagues. At the top of the stepping-stone club rankings are three regular European Cup participants: AFC Ajax (22 players currently in the big-5 were recruited there), SL Benfica (21) and RB Salzburg (20).

In the top 15 positions also are three Belgian teams (KRC Genk, RSC Anderlecht and Club Brugge KV), two further Portuguese clubs (Sporting Clube de Portugal and FC Porto), an additional Dutch one (PSV Eindhoven), as well Swiss (FC Basel), Croatian (Dinamo Zagreb) and Danish (FC København) sides. The B-teams of Real Madrid (4th) and FC Barcelona (11th) also figure high in the rankings. The first non-European team is Boca Juniors (15th).

The 54th edition of the CIES Football Observatory Monthly Report broadens the analysis by revealing that recruitment from a non-big-5 league team is the most common way of entering the five major European leagues (48%), followed by advancement from the youth academy or the B-team of a big-5 league club (39%, up to 50% for players who made their debut in the Spanish Liga) and the promotion from a second division of the club of belonging (13%).

The 290th edition of the CIES Football Observatory Weekly Post ranks clubs from 87 top divisions worldwide according to the number of players fielded in domestic league matches since January 2015. The highest value was recorded for the Colombian side of Deportivo Pasto (176 different players), while the lowest one was measured for Shanghai SIPG in China (44 players).

South American clubs are over-represented among those with the highest squad turnover: 7 in the top 10 positions and 14 in the top 20. Conversely, many top-flight European teams are among those who fielded the least different players in domestic league matches since January 2015, such as Manchester City (52), Real Madrid (54) and Bayern Munich (59).

Generally speaking, the richest leagues are not those where clubs change the most players. The average number of players fielded per club and season varies between 38.7 in the Paraguayan top division and 22.1 in the San Marino one. The highest values in Europe were recorded in Romania (30.5 players per club and season) and Croatia (30.2).

The coronavirus pandemic is heavily impacting the football industry. Issue number 289 of the CIES Football Observatory Weekly Post presents the gaps in the players’ estimated transfer value in the event that no matches will be played and no contract will be extended until the end of June. As such, the total player transfer value at big-5 league level would decrease by 28%: from €32.7 to €23.4 billion.

The extent of the decrease varies according to several factors such as the players’ age, contract duration, career path and recent performance. The greatest loss in relative terms concerns ageing footballers with short-term contracts who played fewer matches during current season than in the previous one. As matter of example, Paul Pogba’s estimated transfer value would almost halve from €65M to €35M.

The greatest potential percentage loss per club was measured for Olympique de Marseille: -38%. Conversely, the lowest one was recorded for another French Ligue 1 team: Stade Brestois (-16%). The values presented have been calculated on the basis of the exclusive CIES Football algorithm. The transfer value ranges for big-5 league footballers before the league shutdown are available here.

Two Borussia Dortmund players head the rankings of big-5 league footballers born in or after 2000 with the highest transfer values according to the CIES Football Observatory algorithm: Jadon Sancho and Erling Håland. The Englishman is valued at almost €200 M and the Norwegian at €101 M. While the value of Sancho probably reached its peak, that of Håland is destined to grow. The top 50 list is available for free in issue number 288 of the Weekly Post.

The Real Madrid’s attacking duo Rodrygo and Vinícius have the third and fourth highest estimated values: €89 M and €74 M respectively. Both Brazilians also have a high potential for progression. With four nationals, England is the most represented origin in the top 10: Jadon Sancho, Callum Hudson-Odoi (5th, €72 M), Mason Greenwood (8th, €50 M) and Phil Foden (9th, also €50 M).

With an estimated value of €53 M, the French midfielder Eduardo Camavinga (Stade Rennais) is the youngest player in the top 10. Another footballer born in 2002, Ansu Fati (FC Barcelona) is worth more than €40 M. The value ranges for all big-5 league footballers is freely available here. The 53rd Monthly Report presents the variables and approach developed by the CIES Football Observatory research team to assess the transfer value of footballers on a scientific basis.

The 287th edition of the Weekly Post ranks clubs from the five major European leagues according to the value on the transfer market of players under contract. The analysis takes into account the 20 players per club with the highest values as per the algorithm exclusively developed by the CIES Football Observatory research team.

With an aggregated value of €1.4 billion, Liverpool heads the table. Jürgen Klopp’s team outranks Manchester City, the two Spanish giants (Barcelona and Real Madrid) and Chelsea. The valuation of the latter team has strongly increased thanks to the outbreak of many young talents following the transfer ban imposed by FIFA to the London club. The German side Paderborn is at the bottom of the table.

The estimate ranges for all of the big-5 league players with a sufficient level of professional experience are freely available here. The 53rd Monthly Report presents the variables included in the statistical model developed by the CIES Football Observatory to assess the transfer values of professional footballers on a scientific basis.

The 286th CIES Football Observatory Weekly Post ranks current big-5 league players according to the age at which they have reached 50, 100, 200 and 300 caps in these competitions. The Milan AC goalkeeper Gianluigi Donnarumma leads the 50 and 100-match tables, while the Real Madrid forward Eden Hazard is at the top for the 200 and 300-match rankings.

Gianluigi Donnarumma played his 50th game in the big-5 even before his 18th birthday, and the 100th at 19.2 years of age only! In both cases, he outranks another goalkeeper, the French Alban Lafont (FC Nantes). The Basque Iker Muniain (Athletic Club) is the outfield footballer having reached the earliest the 50 and 100 caps in the big-5: at 18.2 and 19.8 years of age respectively.

Eden Hazard holds the records of precocity for both the 200 and 300 big-5 league matches. The Belgian was only 23 years old when he played his 200th game in the five major European championships. He is the only player currently in the big-5 who reached his 300th cap before 26 years of age. Five additional footballers played 300 games before their 27th birthday: James Milner, Moussa Sissoko, Iker Muniain, Miralem Pjani? and Cesc Fàbregas.

Issue number 285 of the CIES Football Observatory Weekly Post highlights the players who created the most big chances for their teammates in big-5 league matches over three different periods: last year, last three years and last five years. Lionel Messi is clearly at the head of the tables for the last five and three years, while Ángel Di María tops the last-year rankings.

According to the data from OptaPro, over the five past years, Lionel Messi created a big chance every 90 minutes. The frequency of big chances created by the Argentinean went even up during the last year (87 minutes). This clearly indicates that the Barcelona prodigy is far from being on the downhill slope of his career.

At the second and third positions for the different periods analysed are Ángel Di María and Kevin de Bruyne for the last five years, Thomas Müller and Kevin de Bruyne for the past three, as well as Thomas Müller and Lionel Messi for the last one. During last year, besides Lionel Messi, three other players have created at least one big chance every 90 minutes: Thomas Müller (every 72 minutes), Ángel Di María (82 minutes) and Kevin de Bruyne (every 87 minutes). This is the fab four for chance creation!

Issue number 284 of the CIES Football Observatory Weekly Post ranks 92 top divisions worldwide according to the average number of cards (yellow and red) per game during the current or the last completed one. The figures range from 2.3 in Japan up to 7.0 in Bolivia. Within Europe, the extreme values were recorded in Norway (3.1) and Ukraine (6.2).

The study reveals great geographical differences in aggressiveness put in the game. Eight out of the ten leagues with the most cards are from Latin America: Bolivia, Uruguay, Guatemala, El Salvador, Colombia, Ecuador, Peru and Argentina. At the opposite end, three of the five leagues with the least cards are from Asia: Japan, Vietnam and South Korea.

The values for the five major European leagues vary between 3.7 cards per game in the English Premier League and 5.8 in the Italian Serie A. Per club, the figures vary between 1.0 for Borussia Dortmund and 3.7 for Bologna, while at worldwide level they range between 0.8 for FC Tokyo and 4.0 for Montevideo Wanderers.

The renewal of the fruitful collaboration with OptaPro has allowed the CIES Football Observatory to innovate by developing its first ever technical report on a non-European competition: the Major League Soccer (MLS) of the United States and Canada. The 52nd Monthly Report compares the style of play of the MLS with that of the five major European leagues.

The style of football played in the MLS differs from that of the big-5 in two principal aspects: the pressing on opponents and the aerial game. The average number of duels per match recorded in the MLS is lower than that observed in each of the five major European leagues. This reflects the lesser pressure applied by players on whoever has possession. Consequently, MLS teams have the opportunity to take more shots.

Partly due to the lesser pressure on the player who has possession, the MLS footballers privilege the passing game on the ground. This is reflected in a much lower number of aerial duels: -14% in comparison to the big-5 and -25% in comparison to the English Premier League. The MLS teams also carry out fewer crosses than clubs in any of the five major European leagues.

While the Major League Soccer has already undergone significant development over the past decade, the enthusiasm for soccer in the United States, with the organisation of the FIFA World Cup in focus, will allow the competition to grow further, both economically and sportingly. MLS teams will thus be able to attract more top talents from abroad.

The challenge will also be to develop better footballers on site and retaining them for longer. While some of them will continue to join the best performing European clubs, the eventual improvement of the training system will strengthen the US national team, with very positive fallout for the MLS development and the popularity of soccer across the nation at large.

Issue number 283 of the CIES Football Observatory Weekly Post presents the financial balance for transfers carried out by clubs worldwide during the last two transfer windows. Real Madrid recorded the most negative balance (- €181 million) ahead of Aston Villa (- €169 m) and Barcelona (- €166 m). At the opposite end of the table are Chelsea (+ €205 m), Benfica (+ €167) and Ajax (+ €137 m).

The seven fee paying transfers concluded by Real Madrid during the summer 2019 and winter 2020 transfer windows had a total estimated cost of €330 m (add-ons included). During the same period, the incomes generated by the Spanish team for the release of seven other players were €149 m. On its side, Chelsea earned €250 by transferring 16 footballers, while it only spent €45 m to reinforce its squad (Mateo Kova?i?).

At the level of the five major European leagues, the net balance for transfer operations range from - €844 million for the English Premier League and + €106 m for the French Ligue 1. Negative balances were also recorded in the Spanish Liga (- € 418 m), the Italian Serie A (- € 407 m) and the German Bundesliga (- € 263 m).

Issue number 282 of the CIES Football Observatory Weekly Post presents the list of players born in the 2000s who played the highest percentage of domestic league minutes during current season. Dejan Kulusevski (Parma, on loan from Juventus) tops the table for the big-5 league players ahead of Sandro Tonali (Brescia), Max Aarons (Norwich) and the 17-year-old French talent Eduardo Camavinga (Stade Rennais).

Conor Gallagher (Swansea, on loan from Chelsea) heads the rankings for the second divisions of big-5 league countries. The Spanish prodigy Pedri (Las Palmas) is fourth. Born in 2002, the attacking midfielder has already signed a long-term contract for FC Barcelona. At 19th position is a player born in 2003: Jude Bellingham (Birmingham City). The English midfielder already scored four goals in the Championship.

The Dutchman Sven Botman is at the top of the rankings for players from the other top divisions taken into account. The centre back loaned by Ajax to Heerenveen outranks the Brazilian midfielder Gustavo Assunção (Famalicão) and three very young talents: the Czech forward Adam Hložek (2002, Sparta Prague), the Australian midfielder Louis D’Arrigo (2001, Adelaide) and the Swiss defender Leonidas Stergiou (2002, St-Gall).

Issue number 281 of the CIES Football Observatory Weekly Post compares points achieved by teams from 31 European leagues with points expected according to a statistical model taking into account ball possession, as well as the number and distance of both shots taken and conceded as per InStat data. The analysis highlights the great efficiency of clubs such as Benfica (+0.71 points per match), Liverpool (+0.66), Juventus (+0.64), Schalke 04 (+0.57) and Valencia (+0.55).

The pitch production of Benfica should have allowed them to achieve 2.11 points per match compared to 2.82 in reality. The greatest positive gap out of the 496 clubs from the 31 leagues surveyed was recorded for Astra Giurgiu (+0.85). The Romanian side obtained almost two points per match despite having conceded more shots than those taken and having had only about 45% of ball possession. The same holds true for Turkish league leader Sivaspor (+0.73).

The greatest negative gap overall was registered for Heart of Midlothian: 0.62 points achieved compared to 1.39 expected (-0.77). Champions League round of 16 participants Atalanta (-0.71) and Napoli (-0.61) were also particularly inefficient with respect to their pitch production. Manchester City (-0.36) and Chelsea (-0.33) are at the bottom of the Premier League efficiency rankings. More exclusive InStat data is accessible in the CIES Football Observatory Performance Atlas.

Issue number 280 of the CIES Football Observatory Weekly Post ranks teams from 35 European domestic leagues according to their number of fouls per game as per InStat data. Champions League titleholders Liverpool FC committed the least fouls per match so far this season (8.1). This is partially related to the less strict refereeing style in the English Premier League: 20.4 fouls whistled per game compared to an average of 27.2 in the 35 competitions surveyed.

Eight Premier League teams are in the top 18 positions of the rankings: Liverpool, Newcastle, Bournemouth, Leicester, Chelsea, Norwich, Tottenham and Manchester City. If we relate fouls committed to the average measured at league level, Hamburger SV heads the table (-32% of fouls with respect to rivals), ahead of Slovan Bratislava (-29%) and Shakhtar Donetsk (-27%). Vojvodina made the most fouls per match overall (22.9), while Zlaté Moravce committed the most compared to league rivals (+38%).

Per league, the lowest average number of fouls per game whistled by referees was recorded in the English Premier League (20.4), the Danish Superliga (21.0) and the Dutch Eredivisie (21.6). At the opposite end of the table are the top divisions of six Eastern European countries: Serbia (34.9), Bulgaria (31.6), Czech Republic (31.4), Romania (31.0), Poland (30.9) and Ukraine (30.5).

For the first time, a CIES Football Observatory report turns its eye exclusively to Latin America. It analyses the squads of four leagues: the Brazilian Serie A, the Argentinean Superliga, the Chilean Primera División and the Mexican Liga MX. Il notably reveals the specificity of the Mexican league with respect to the presence of footballers imported from abroad. Expatriates account for the majority of players in line-ups, while they only play about a tenth of minutes in Brazil and Argentina. Access the study.

The report also brings to light the greater emphasis on the promotion of talents from youth academies by Argentinian teams. Boca Juniors is the most important training club, followed by three other clubs from Argentina: Vélez Sarsfield, River Plate and Newell’s Old Boys. The most important training clubs for the other three countries studied are São Paulo FC in Brazil, Atlas Guadalajara in Mexico and Universidad de Chile in Chili.

The study also shows the central role of Argentina as a provider of players for the leagues analysed. Indeed, Argentinians constitute the most numerous contingents of expatriates in Mexico, as well as in Chili and Brazil. On the contrary, only eight Brazilians are expatriated in the leagues studied (all in Mexico). The other countries with many expatriates in the championships taken into account are Colombia, Uruguay and Paraguay.

Finally, the report illustrates the specificity of the Brazilian Serie A regarding the plethora of players used by teams. This situation reflects the status of Brazil as a global source of labour par excellence. From this point of view, just playing a few matches can open the doors towards a transfer abroad, even though not in the most prestigious football countries.

The CIES Football Observatory opens a new exciting decade of football analytics with the exclusive publication of its traditional list of the big-5 league players with the greatest estimated transfer values. At the top three positions of the table are Kylian Mbappé (France and Paris St-Germain), Raheem Sterling (England and Manchester City), as well Mohammed Salah (Egypt and Liverpool). Issue number 279 of the Weekly Post presents the 166 footballers in the big-5 valued at more than €50 million.

Per position, the most expensive players from a transfer value perspective are Alisson Becker for goalkeepers (€77 M), Virgil van Dijk for centre backs (€93 M), Trent Alexander-Arnold for full backs (€110 M), James Maddison for midfielders (€112 M) and Kylian Mbappé for forwards (€265 M). Eleven out of the 20 big-5 league footballers with an estimated value of at least €100 million play for English Premier League clubs.

There are at least two players worth more than €100 M are in each of the remaining big-5 leagues: three in the Liga (Messi, Griezmann and João Felix), two in the Ligue 1 (Mbappé and Neymar), two in the Serie A (Martínez and Lukaku), as well as two in the Bundesliga (Sancho and Werner). More information about the exclusive approach developed by the CIES Football Observatory research team to estimate transfer values on a scientific basis is available in this methodological note.

The CIES Football Observatory has developed a property algorithm to assess the performance of footballers from the exclusive data produced by the leading sports company OptaPro. Issue number 278 of the Weekly Post presents the MVP per big-5 league club, as well as the top values for each of the six areas of the game analysed. Only players fielded for at least nine (MVPs) and respectively six (per domain) full domestic league matches are included.

The MVPs are footballers whose performance had the biggest influence in their teams’ results. We notably find Marco Verratti at Paris St-Germain, Lionel Messi at Barcelona, Toni Kroos at Real Madrid, Kevin de Bruyne at Manchester City, Virgil van Dijk at Liverpool, Ciro Immobile at Lazio, Jamie Vardy at Leicester City, Dimitri Payet at Olympique Marseille, Miralem Pjani? at Juventus, Sven Bender at Bayer Leverkusen and Milan Škriniar at Inter.

At Real Madrid, five different footballers head the tables per area of the game: Raphaël Varane for rigour (duels), Carlos Casemiro for recovery (interceptions), Toni Kroos for distribution (passes), Eden Hazard for take on (dribbles) and Karim Benzema for both chance creation (assists) and shooting (attempts). At Barcelona, three players only top the rankings: Lionel Messi for all of the attacking indicators, Clément Lenglet for rigour and Sergio Busquets for both recovery and distribution.

The leading sports data company InStat has developed an exclusive Index to assess the performance of football players on an objective basis. Issue number 277 of the CIES Football Observatory Weekly Post presents the top 10 rankings for 35 European competitions. The highest InStat Index overall was recorded for the recent Ballon d’Or winner Lionel Messi: 401.

Per position, the top three ranked footballers are Frederik Rönnow, Wojciech Szczesny and Marwin Hitz among goalkeepers, Virgil van Dijk, Joël Veltman and Willy Boly among centre backs, Andrew Robertson, Ricardo Pereira and Ben Chilwell among full backs, Kevin de Bruyne, Papu Gómez and Marco Verratti among midfielders, as well as Lionel Messi, Hakim Ziyech and Kylian Mbappé among forwards.

The values for all players from the 35 European leagues covered are available in the exclusive InStat Index tool on the CIES Football Observatory website. This unique tool allows users to filter footballers per league, position and age. It is thus possible to focus on specific players’ profiles, as extensively done by club representatives from a scouting perspective.

No outfield footballer played a higher percentage of domestic league minutes of a big-5 league team in the 2010s as Lionel Messi. The Argentinean was fielded for 83.4% of total minutes played by Barcelona in the Liga. This is the second value overall behind that measured for Steve Mandanda (84.2% of Olympique Marseille minutes). The 276th issue of the CIES Football Observatory Weekly Post presents the most fielded footballer for each of the 42 clubs always present in the big-5 in the 2010s.

The 50th Monthly Report analyses the make-up of these teams over the course of the decade that is about to end. The unique case of Athletic Club Bilbao is reflected in almost all the indicators analysed. FC Barcelona’s case shows that territorial anchoring can be a plus even for a global club. Their success is for the most part linked to the exceptional qualities of home-grown players such as Lionel Messi, Xavi, Andrés Iniesta, Gerard Piqué or Sergio Busquets.

Although money is more than ever a key factor, other elements come into play. Squad stability stemming from good strategic planning, as well as the ability of clubs to get the best out of the talents trained in their youth academies and to stimulate a strong sense of belonging to all parties concerned (players, staff, supporters, etc.), remain crucial success criteria even in the today’s hyper-commercial and globalised environment.

Issue number 275 of the CIES Football Observatory Weekly Post maps the origin of expatriate players in 31 European top divisions. With 466 representatives, Brazilians are the most numerous (10.3% of the total number of expatriates), followed by the French (350 players). However, the latter are the most present in the big-5 European leagues: 115 French players abroad compared to 104 Brazilians.

Footballers who grew up in France represent the largest contingent of expatriates in the Premier League (41 players, 15.7% of total playing time of expats), the Bundesliga (28, 8.0%) and the Liga (25, 13.6%). Brazilians are the most present in the Serie A (33 players, 7.3% of minutes played by all expatriates) and the Ligue 1 (25, 5.4%). Brazil is the most represented origin also in Portugal, Russia, Ukraine, Bulgaria and Finland. They are present in all of the countries covered except Scotland.

With 224 representatives in the 31 European top divisions and 67 expatriates in the five major championships, Spain is the third main exporting country. For a more global vision of player international mobility, the Atlas of Migration of the CIES Football Observatory presents additional data on the presence and distribution of expatriates in 147 leagues from 98 countries worldwide.

Dominating opponents does not always lead to success. However, the InStat data analysed in the 274th CIES Football Observatory Weekly Post shows that most of the best performing teams are able to maximise their passes in the opponent’s third of the pitch, while minimising the opponent’s passes in their own third. The best ratio overall in the 35 European leagues surveyed was measured for Manchester City.

Guardiola’s team made on average 210 passes per match in the opponent’s third, versus only 59 by the opponents in their own third (ratio of 3.55). This ratio is only 1.9 for Premier League leaders Liverpool (180 passes versus 85). The greatest number of passes in the opponent’s third part of the field was recorded for AFC Ajax (220 per match). The Dutch side has the second best ratio (3.43), ahead of Steven Gerrard’s Rangers Glasgow (3.03).

The worst ratio overall was observed for another Scottish side: Hamilton Academical (0.39). A very negative ratio was also recorded for Newcastle United (0.41). Fulham (1.78) has the most positive ratio in the Championship ahead of Marcelo Bielsa’s Leeds United (1.58). Nottingham Forest is at the opposite end of the table (0.71). More data is available in the exclusive CIES Football Observatory & InStat Performance Atlas.

Issue number 273 of Weekly Post presents the top 50 transfer values for players currently on loan in big-5 league teams. At the head of the table is Philippe Coutinho. However, the price for the Brazilian as estimated by the CIES Football Observatory algorithm (€96.5M) is lower than the option to buy negotiated between Bayern and Barcelona (€120M).

Four other players on loan have an estimated value greater than €50M: Dani Ceballos, Martin Ödegaard, Harry Wilson and Mauro Icardi. While there is in principle no option to buy for the three former players, Paris St-Germain can sign Mauro Icardi for €70M. This is currently a relatively high fee, but it could be no more the case if the Argentinean goes on playing and scoring as he managed to do in October.

With regard to Stefano Sensi and Duván Zapata, the levels of their options to buy are already significantly lower than the estimated values. Inter and Atalanta will probably not hesitate to exercise them. More information on the exclusive CIES Football Observatory approach to assess on a scientific basis the transfer value of professional footballers is available here.

The 49th Monthly Report of the CIES Football Observatory analyses the demographic characteristics of players from 31 European top division clubs. It notably reveals that the trend towards less stability and a greater international mobility has declined over the past year. While the level of expatriates has reached a new record (41.8%), the increase was less marked than in previous years: +0.2% as opposed to an average of +1.2% between 2014 and 2018.

For the first time since the first census in 2009, the percentage of club-trained players has grown. However, this increase was very limited (+0.2%). It is thus difficult to claim that the tendency towards fewer club-trained footballers has reversed. In the same vein, the halt in the decrease in the average length of stay of players in their club of employment does not necessarily imply a return towards more stability.

From next year onwards, it will be very interesting to monitor if the increasing economic disparities between teams from different countries will push a greater number of clubs with limited means to concentrate on the promotion of locally trained talents. This holds particularly true in Eastern Europe (Romania, Bulgaria, Hungary, etc.) and Southern Europe (Cyprus, Greece, Turkey, etc.), where transfer market activity is particularly prevalent. Access the study!

The effective playing time of a football match greatly varies according to league and club. According to the exclusive InStat data on 35 European competitions, during current season, the highest percentage of effective playing time was measured in the Swedish top division (on average 59.7% of minutes per match). At the opposite is the Czech league (50.2%). The data at both league and club level are available in the 272th edition of the CIES Football Observatory Weekly Post.

The findings reveal great discrepancies per continental area. The higher values recorded in Northern and Western Europe reflect more open styles of play and a greater player discipline. Among the five major European championships, the German Bundesliga (57.1%) has the highest effective playing time, while the Spanish Liga has the lowest (53.3%).

At club level, the record percentage of effective playing time was measured for the matches of the Swedish side GIF Sundvall (63.2%). AZ Alkmaar (62,9%) and Helsingborgs (62,8%) also are in the top three. At the other extreme are three Spanish teams: Alcorcón (45,8%), Getafe (45,9%) and Rayo Vallecano (46,2%). The highest values for big-5 league clubs were recorded for Bayern Munich (62.0%), Olympique Lyonnais (61.5%) and Paris St-Germain (60.7%).

Which teams train the most professional footballers? As every year, the CIES Football Observatory has established the rankings of the best training clubs for players active in the big-5, as well as for footballers in 31 European top divisions. Real Madrid and Partizan Belgrade head the tables. The top 60s are available in issue number 271 of the Weekly Post.

For big-5 league players, Real Madrid (39 footballers trained, +3 compared to last year) outranks Barcelona (34, same number) and Olympique Lyonnais (30, -5). At the level of the 31 top divisions, Partizan Belgrade (75 players trained, +6 with respect to last year) outranks AFC Ajax (72, -5) and Sporting Clube Portugal (63, +5). The top 50s rankings for 2018 are available here.

Following UEFA definition, training clubs are teams where footballers played for at least three seasons between the ages of 15 and 21. The percentage of minutes played by club-trained footballers in all of the teams from the 31 competitions studied is available in the CIES Football Observatory Demographic Atlas. In addition, more exclusive data is regularly published through Twitter, Facebook and Instagram.

The CIES Football Observatory research team has developed an exclusive approach to measure the experience capital of footballers according to their playing time and the level of matches played. Issue number 270 of the Weekly Post presents the 50 highest figures worldwide for players born in 2000, as well as the top 50 for footballers born in or after 2001.

For players born in 2000, the Englishman Jadon Sancho (Borussia Dortmund) outranks his countryman Ryan Sessegnon (Tottenham) and the Dutchman Kik Pierie (AFC Ajax). The second highest figure outside of the big-5 European leagues was measured for the Danish Mikkel Damsgaard (Nordsjaelland), while that for footballers playing outside of Europe was recorded for the Venezuelan Cristian Casséres (New York Red Bulls).

Rodrygo Goes (Real Madrid) heads the table for players born in or after 2001. The Brazilian prodigy ranks in the top 10 also by considering footballers born in 2000: 8th. The Paraguayan Fernando Cardozo (Boavista) is the second most experienced U19 player, while at third position is a 2002-born footballer: Adam Hložek (Sparta Praha). The youngest player in the lists is the 16-year-old midfielder Daniel Leyva (Seattle Sounders & Tacoma Defiance).

The 48th Monthly Report of the CIES Football Observatory analyses the evolution of the number and characteristics of footballers having played on loan for teams of the five major European championships during the last decade. It shows that clubs from these leagues take more and more players on loan: from 2.62 per club and season between 2009 and 2014, up to 3.09 between 2014 and 2019 (+18%). In 2018/2019, footballers on loan played a record number of minutes in the big-5: 11.5%.

This evolution is notably explained by the tendency of wealthy teams (Manchester City, Chelsea, Juventus, etc.) to put under contract an increasing number of footballers with a sufficient sporting level to play in the major European leagues. This puts other clubs in a greater state of dependency when making up their squads, thus increasing their likelihood to take players on loan.

The study also shows that loans constitute in most of the cases a step towards a definitive departure. Indeed, only 29.6% of footballers lent to big-5 league clubs between 2009/10 and 2018/19 return to their owner team at the end of the loan period. In 27% of the occurrences, they were loaned again, while in the remaining 43.4% of cases they were transferred on a permanent basis to another team.

Regulation makes sense in avoiding the misuse of loan strategies orientated not towards a legitimate sporting logic to develop the potential of a young player on which the loaning team really counts, but rather towards an economic logic that aims to generate profits from the transfer market or a political logic aiming at exercising undue influence on rival clubs. In order to be effective, these measures should be implemented in parallel to the regulation of the questions of buy-back options (recompra) and the multi-ownership of clubs.

The partnership with the football data company InStat allows the CIES Football Observatory to present exclusive analysis on the technical performance of teams from 35 European competitions. Issue number 269 of the Weekly Post highlights domestic league matches during which a team had the highest percentage of ball possession (calculated out of effective playing time). The record figure for current season was measured for Fulham against Millwall on the 21st August: 78.7%.

The loss with the highest possession was recorded for Tottenham against Newcastle: 74.8% on the 25th August (0-1). Apart from Fulham and Tottenham, Shakhtar Donetsk (in two away matches), Paris St-Germain, Celtic FC, Borussia Dortmund, Ludogorets Razgrad, FK Partizan (also in a game away) and RB Salzburg are in the top ten positions of the rankings.

The Weekly Post presents the top 10 possession figures for each of the 35 championships analysed. In addition, the freshly updated CIES & InStat Performance Atlas presents additional data on six key technical indicators referring to defence, possession and attack. By clicking on teams, the tool allows users accessing exclusive statistics for up to the last 10 domestic league matches played. Please contact us for more information about the wide array of possibilities offered by subscribing to InStat.

Issue number 268 of the CIES Football Observatory Weekly Post presents the percentage of domestic league minutes played by footballers signed at the start of the season for all of the big-5 league clubs. Last Champions League finalists, Tottenham (5.0%) and Liverpool (8.3%), as well as Manchester City (7.7%), are among the 14 teams where new recruits played less than one tenth of minutes.

The figures for Manchester United and Chelsea are much higher: 25.8% and 33.6% respectively. Among Champions League participants, only LOSC Lille fielded new signings for a greater percentage of minutes than Chelsea: 42.5%. The highest proportion in the big-5 was measured for Fiorentina (69.5%), a club recently taken over by a new wealthy owner.

The most stable teams are to be found in the Premier League, where new recruits played so far only 15.7% of minutes (maximum 50.4% at Aston Villa). At the opposite end of the table is the Italian Serie A: 29.6% (minimum 5.5% for Atalanta). The averages measured in the other three leagues of the big-5 are 22.7% for Bundesliga, 24.0% for the Liga (maximum 54.3% for Sevilla) and 26.7% for Ligue 1.

Issue number 267 of the CIES Football Observatory Weekly Post analyses the exclusive data produced by our partners InStat by ranking Champions League teams according to the average length of the passes achieved in domestic league games so far this season. Past edition semi-finalists Ajax have the lowest figure (15.96 meters), ahead of Paris St-Germain (16.17) and Barcelona (16.56).

At the opposite end of the table are Czech champions Slavia Praha with an average length of 19.82 meters (+24% compared to Ajax). Title holder Liverpool has so far achieved the fourth longest passes among group stage participants: 19.45 meters on average. This figure is significantly higher than for their main Premier League rivals Manchester City (17.39).

The majority of high-profile teams are among those making the shortest passes. Apart from Liverpool, the only recent Champions League finalist with an average length of passes greater than 18 meters is Atlético Madrid. Diego Simeone’s team achieved the third lowest number of passes per game (379), while Lucien Favre’s Borussia Dortmund made the most (735).

For the first time in history, a football club invested more than one billion euro in transfer indemnities to assemble its squad: Manchester City. Following last summer transfer window, two clubs are close to this figure: Paris St-Germain (€913 million) and Real Madrid (€902 million). Issue number 266 of the CIES Football Observatory Weekly Post presents the data for all teams in the big-5.

The gap between the costliest and cheapest squad per league is x148 in the Liga (Real Madrid vs Mallorca), x114 in the Ligue 1 (Paris St-Germain vs Nîmes), x85 in the Bundesliga (Bayern vs Paderborn), x63 in the Serie A (Juventus vs Lecce) and x32 in the Premier League (Manchester City vs Norwich). This reflects the great financial divides in European football.

The average transfer expenditure to sign current squad members per league is €345 M in the Premier League, €167 M in both the Liga and the Serie A, €124 M in the Bundesliga and €118 M in the Ligue 1. More exclusive financial analysis on the big-5 league transfer market is available in the 47th edition of the CIES Football Observatory Monthly Report.

All things being equal, the price of players during the last transfer window went up by 31% compared to the previous year. Since 2014, the annual inflation growth rate on the transfer market for big-5 league footballers has been 26%. With respect to 2011, the same player costs now almost three times more. More exclusive analysis is available in the 47th edition of the CIES Football Observatory Monthly Report.

The amounts at stake on the football players’ transfer market have strongly increased over the past decade. At big-5 league level, the investments in transfer indemnities have grown from €1.5 billion in 2010 to a new record of €6.6 billion in 2019 (+340%). During this period, big-5 league clubs have recorded a cumulative deficit of €8.9 billion. English Premier League clubs alone have a total net negative balance of €6.5 billion, with a record deficit for Manchester City (€1.1 billion).

Despite the increase in spending and a strongly inflationary context, the growing recourse by clubs to payments spread out over several years shows that more and more teams are finding themselves at the limit of their financial capabilities. In an increasingly speculative and uneven environment, a growing number of clubs, even within the most powerful leagues, include the profits made on the transfer market into their financial model. This situation is not without danger for their stability, independence and competitiveness.

Read the Report

Issue number 265 of the Weekly Post presents the 100 players from the five major European leagues with the highest transfer values according to the freshly updated and further improved CIES Football Observatory algorithm. Three forwards are in the top three positions: Kylian Mbappé (€252M), Mohammed Salah (€219M) and Raheem Sterling (€208M).

Apart from strikers, the most expensive footballers per position are Alisson Becker (€107M) for goalkeepers, Trent Alexander-Arnold (€130M) for defenders and Paul Pogba (€125M) for midfielders. Lionel Messi (€167M) heads the rankings for players over 31 years of age, while Cristiano Ronaldo (€118M) tops the table for footballers aged 33 or more.

The CIES Football Observatory algorithm takes into account a wide array of variables such as age, contract, position, minutes, goals, international status, team results, etc. The estimates refer to the value for the most likely recruiting club. The price range for all of the big-5 league players can be accessed for free here. Deeper analysis is available on a consultancy basis.

This new Monthly Report analyses the composition of teams participating in the five of the most developed women’s professional leagues worldwide: four European leagues (Germany, Sweden, France and England), as well as the National Women’s Soccer League in the United States. It reveals that the age of players increases, international mobility grows and the concentration of the best footballers within a limited number of clubs independently of their origin pursues its course.

The average age of players on the pitch has risen from 25.1 years of age in 2017 to 25.5 in 2019. The German Bundesliga is the only championship in which the average age on the pitch has fallen over the last three years. It is now the league fielding the youngest players among those covered by the study: 24.7 years of age (-0.8 since 2017). At the opposite end is the United States National Women’s Soccer League: 27.5 years of age (+1.3 years since 2017).

The percentage of minutes played by expatriates has increased for the third year running reaching a figure of 32.4% (+4.4% in comparison to 2017). The most notable increase was recorded in England (+7.5%), where more and more clubs invest in women’s football through reproducing the same mechanisms already observed in the men’s game. The total number of expatriates in the leagues covered increases year by year: from 300 in 2017, the figure reached 348 in 2018 and 379 in 2019.

Numerous teams play with a majority of footballers with international status. The percentage of minutes played by the latter reaches 99.0% at Bayern Munich and 98.8% at Arsenal. It is greater than 90% in three other teams: Wolfsburg, Manchester City, as well as at the multiple European champions Olympique Lyonnais (94.2%).

Though encouraging, the evolution noted shows the importance of reflecting on regulatory mechanisms to limit the negative effects due to market logics already observed in the men’s game such as, among others, the speculation on young players, the concentration of resources and competitive imbalance.

What is the percentage of points won by champions in the five major European leagues? Issue number 264 of the CIES Football Observatory Weekly Post answers this question for the last twenty seasons. The analysis reveals a progressive increase in the percentage of points achieved by champions.

On average, big-5 league champions obtained 69.9% of points for the five-season period between 1999/2000 and 2003/2004. This percentage went up to 73.9% during the following lustrum, to 77.7% between 2010 and 2014, and again up to 80.5% for the last five seasons. This reflects an ongoing trend towards competitive imbalance.

The record figure overall was registered for Juventus in 2013/14: 89.5% of points. At the other extreme is Olympique Lyonnais in 2002/03: 59.6%. All 2018/19 big-5 league champions achieved at least three quarters of points: from 86.0% for Manchester City (second highest score in the English Premier League history) to 76.3% for Barcelona.

Issue number 263 of the CIES Football Observatory Weekly Post analyses the average length of passes by teams from 35 European domestic leagues. The study highlights big discrepancies in playing styles. There are almost 8 meters difference between the teams that executed the longest and shortest passes: Rotherham United (23.42m) and Paris St-Germain (15.85m). 

Many very competitive teams are in the top 25 of the rankings for the shortest passes, including Champions League semi-finalists FC Barcelona (2nd) and AFC Ajax (5th), as well as Europa League finalist Chelsea FC (4th). The vast majority of teams executing the longest passes are in the bottom-half of the table in their respective leagues. Getafe CF is the exception that confirms the rule. 

The analysis per league also reveals the persistence of cultural differences in the approach of the game. Teams from the Scottish Premier League (21.08m) and the English Championship (20.58m) execute on average the longest passes. At the opposite end of the table, we find the French Ligue 1 and the Finnish Veikkausliiga (18.89m in both cases). Data comes from InStat.

For the third year, the CIES Football Observatory analyses the presence of expatriate players in 147 leagues from 98 national associations. Brazil is clearly at the top of the rankings for countries exporting the most footballers (1,330 players), ahead of France (867) and Argentina (820). Alone, these countries export almost a quarter of footballers (22.5%). Overall, the number of expatriates increased by 5.0% compared to 2018.

During last year, the number of expatriates has increased for each of the three principle exporting countries: Brazil (+64 players, +4.8%), France (+37 players, +4.3%) and Argentina (+57 players, +7.0%). The number of Spaniards abroad has also strongly increased (+61 players, +14.3%). This is the second biggest increase in absolute terms after that of the Brazilians.

The most frequented migratory route originates from Brazil and ends in Portugal (261 players). The migration of Argentinians to Chili (116 players) is the second principle axis. Two migratory channels departing from England also involve many footballers: the first ends up in Scotland (113 players), while the second leads to Wales (92 players).

England and Italy are the chief importing countries of footballers. The professional clubs of these countries employ 728 and 636 expatriate players respectively. Without taking into account the 139 citizens of the other UK nations present in England, it is thus in Italy that the greatest number of players imported from abroad are to be found.

The CIES Football Observatory research team is also proud to disclose the brand new Atlas of Migration mapping the international flows of footballers.

Issue number 262 of the CIES Football Observatory Weekly Post presents the three best and worst teams per league in terms of points that they should have achieved according to their pitch production. Virtual points were projected according to a statistical model including shots taken and conceded (both on target and from the box), as well as the percentage of ball possession.

With respect to the indicators selected, Napoli and Atalanta should have achieved more points than the Italian Serie A champions Juventus. However, Massimiliano Allegri’s players were much more efficient. In the Greek top division, both Olympiacos and AEK Athens had a greater pitch production than champions PAOK. Marcelo Bielsa’s Leeds United tops the production rankings in the English Championship.

According to pitch production, Lucien Favre’s Borussia Dortmund should only have ranked fourth in the German Bundesliga behind Bayern Munich, RB Leipzig and Bayer Leverkusen. The Ruhr team was thus particularly efficient. In Turkey, ?stanbul Ba?ak?ehir virtually outranks Be?ikta? and Galatasaray. More data is available in the CIES Football Observatory Performance Atlas powered by InStat data.

Issue number 261 of the Weekly Post presents the top 50 list of the U20 players from the big-5 with the highest transfer value according to the CIES Football Observatory algorithm. The English full international Jadon Sancho heads the table with an estimated value of €150M. Borussia Dortmund’s winger outranks Arsenal’s Mattéo Guendouzi (€70M) and AS Roma’s Nicolò Zaniolo (€67M).

Four other big-5 league players born on or after January 1st 1999 have an estimated value greater than €50M: Kai Havertz (Bayer Leverkusen), Declan Rice (West Ham), Gianluigi Donnarumma (Milan AC) and Vinícius Júnior (Real Madrid). Footballers from 18 national associations feature in the top 50 list. The most represented country is France (13 players), followed by England (9).

The updated transfer valuations for all players from the five major European competitions are available here.

The 260th edition of the CIES Football Observatory Weekly Post analyses the age at which players fielded during this season in 24 European top divisions were signed by their clubs of employment. Academy graduates are not included in the sample. RB Leipzig recruited its footballers at the youngest age (21.43 years on average), while MKE Ankaragücü signed them at the oldest one (29.28 years).

The second and third lowest values for age at recruitment at big-5 league level were registered for two other teams with a transfer strategy clearly focused on the signing of young talents: Real Madrid (21.95 years on average) and Olympique Lyonnais (22.64 years). Many other very competitive teams are in the top 20 positions of the rankings. At the opposite end of the table is Parma (27.35 years).

CSKA Moskva is the club from the 19 further European top divisions surveyed that signed its squad members at the youngest age: 21.9 years on average. The Russian side outranks the club having fielded so far the youngest footballers in domestic league games during current season: FC Nordsjælland (see Demographic Atlas). At third position is RB Salzburg, ahead of five Dutch and two Belgian teams.

Marcelo Guedes (Olympique Lyonnais) heads the big-5 league rankings of players having won the highest percentage of defensive air challenges in domestic league matches this season: 136 out of 159 (85.5%). The Brazilian outranks three English Premier League players: Harry Maguire, Virgil van Dijk and Shane Duffy. The top 50s for the big-5 and 26 other European competitions are available in issue number 259 of the CIES Football Observatory Weekly Post.

The top ranked players for the remaining big-5 European leagues are Dimitrios Siovas (CD Leganés), 37-year-old Bruno Alves (Parma) and Mats Hummels (Bayern). Three other world champions are in the top 50 table: the Spaniards Gerard Piqué and Sergio Ramos, as well as the French Raphaël Varane. Only footballers with at least 80 challenges according to the statistics provided by our partners InStat were included in the analysis.

Heart of Midlothian’s centre back Christophe Berra heads the table for players in the other 26 competitions surveyed. The Scottish won 233 of his 268 defensive aerial challenges: 86.9%. He outranks three other central defenders: Felipe Augusto (FC Porto), Jake Cooper (Millwall) and the captain of the French Ligue 2 club of Clermont Foot Julien Laporte. The top ranked full back is the Dutch full international Denzel Dumfries (PSV Eindhoven).

The 44th Monthly Report of the CIES Football Observatory analyses match attendances in 51 national football leagues from 42 countries. Germany appears as the footballing country par excellence. Although also very popular, English and Spanish clubs have considerably less spectators than German teams. Outside of Europe, Mexican clubs attract the biggest crowds.

The study of the changes since 2003 reveals the growing enthusiasm for football in the United States and Canada. Despite the increase in the number of teams participating in the MLS, average attendances have consistently increased to break the 20,000-spectator threshold over the past five years. This limit has also been broken in China, where football’s popularity is henceforth also well established.

With over 80,000 spectators per match, Borussia Dortmund is top of the rankings for attendance by club. The Ruhr team is ahead of four football giants: Manchester United, Barcelona, Bayern Munich and Real Madrid. Five German clubs are in the top ten rankings (the two already cited, Schalke 04, Hamburg and Stuttgart). Atlanta United is the most popular non-European club (10th in total).

Issue number 258 of the CIES Football Observatory Weekly Post ranks 27 top division leagues of UEFA member countries according to the percentage of goals scored during the current season by expatriate footballers. At the top of the table is Cyprus (86.7% of foreign goals), ahead of Turkey (80.7%) and England (68.8%).

In nine other leagues, foreign goals accounted for more than half of total goals. At the opposite end of the table, expatriate players scored less than one third of goals in four countries only: Ukraine (25.5%), Serbia (27.6%), Israel (27.9%) and the Czech Republic (30.4%). The lowest percentage at big-5 league level was measured in the French Ligue 1 (35.6%).

Big discrepancies also exist at club level. The figures vary from 0% (Paksi FC, EA Guingamp, Athletic Club Bilbao, etc.) to 100% (AEK Larnaca, Rizespor, FK Senica). In the English Premier League, they go from 97.4% at Wolverhampton to 20.5% at Leicester City. More data on the composition of squads is available in the exclusive CIES Football Observatory Demographic Atlas.

Issue number 257 of the CIES Football Observatory Weekly Post presents the players with the highest estimated transfer value per big-5 league club. The potentially most expensive player overall, Kylian Mbappé (€228 million), represents 25.9% of the total squad value of Paris St-Germain. A similar percentage was measured for Jadon Sancho (€148 million, 24.9%) at Borussia Dortmund.

Despite his age, Lionel Messi remains the most valuable FC Barcelona’s player: €171 million. The Argentinean is the oldest footballer among those with the highest transfer value out of all big-5 league clubs. At Juventus, 34-year-old Cristiano Ronaldo (€125 million) is only outranked by Paulo Dybala (€142 million).

Eden Hazard (€121 million) is the most expensive Chelsea FC’s squad member. The Belgian also has the highest transfer value among footballers with only one year of contract remaining, ahead of Timo Werner (€70 million). The German striker is the most valuable RB Leipzig’s player. If they do not extend their contract, both footballers will probably be transferred during the next transfer window.

The CIES Football Observatory has developed an exclusive approach to measure the technical performance of players on an objective basis using data provided by OptaPro. Issue number 256 of the Weekly Post presents the best performing big-5 league footballers for last 1,000 minutes played. The rankings only include players fielded for at least 630 minutes since January 1st 2019.

Four Atalanta players are in the best XI for Serie A: Timothy Castagne, Josip Ili?i?, Papu Gómez and Duván Zapata. The only Juventus player fielded for at least 630 domestic league minutes in 2019 is also present in the best formation: Daniele Rugani. Five Barcelona footballers figure in the Liga’s best XI, including Lionel Messi.

The most represented teams in the remaining leagues are Bayern Munich in the Bundesliga (four players), Manchester City in the Premier League (five players) and Paris St-Germain in the Ligue 1 (six players). The youngest footballers per league are Gianluigi Donnarumma, Sergio Reguilón, Jadon Sancho, Marcus Rashford and Kylian Mbappé.

Issue number 255 of the CIES Football Observatory Weekly Post ranks big-5 league teams according to the ratio between fouls suffered and committed during the current season using data from OptaPro. FC Barcelona players suffered the most fouls with respect to those committed (1.5 times). At the opposite end is Brighton & Hove with a ratio of 0.68.

The highest number of fouls committed per match was measured for Getafe (17.1). In the other leagues, the top values were recorded for Torino (16.8), Dijon (15.8), Augsburg (14.2) and Brighton & Hove (12.8). Conversely, Borussia Dortmund players have on average committed the least fouls per game (8.4). In the other championships of the big-5, the lowest figures were observed for Manchester City (8.5), Barcelona (10.5), Napoli (10.7) and Nice (11.2).

The average number of fouls per fixture varies between 20.9 in the Premier League and 27.0 in the Liga. This strong gap partially reflects the existence of different styles of refereeing. In the remaining leagues, these values are 24.0 in Bundesliga, 26.4 in Ligue 1 and 26.6 in Serie A. Among players fielded for at least 1,000 domestic league minutes, Moussa Doumbia (Reims), Amine Harit (Schalke 04) and Borja García (Girona) are those fouled most often.

The 43rd Monthly Report of the CIES Football Observatory analyses the evolution of the origin of players fielded over the past ten years in the English Premier League. It shows that the playing time of footballers having grown up in England has progressively fallen to reach a new negative record level over the current season: 35.2%. A similar trend was observed for goals scored: 30.7%.

On the contrary, the proportion of continental Europeans has steadily increased throughout the decade analysed. New records have been measured during the current season both at the level of the percentage of minutes (45.0%) and at the level of goals scored (43.3%). Since the 2017/18 season, continental European nationals are more numerous on Premier League pitches than UK players. 

Within the context of Brexit, a possible limit on the scope of international recruitment may oblige the majority of Premier League teams to modify their transfer strategies. However, the rise of a new generation of very promising Englishmen suggests that, on strictly sporting terms, such a change may not negatively affect the competitiveness of Premier League teams. It could even strengthen the English national team.
