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).
