Since last summer, the CIES Football Observatory has had the pleasure of working with the French leading company SkillCorner, specialised in the generation of physical data on football players. The 68th Monthly Report analyses the distances covered, notably according to running speed, for 7,855 matches played during the 2020 or 2020/21 seasons in 31 leagues from both Europe and America.

The study shows that players from European teams tend to cover more ground than those from South American clubs, which reflects a more rapid playing style. However, the gaps between the competitions analysed are not very marked. The values per outfield player and match stretch from 10.3km for the Spanish Liga and 9.6km in the Brazilian Serie A.

A significant link exists between the players’ age and distances covered, whether for total distance or that ran in high intensity (> 19.8 km/h). The strongest relation was recorded between the forwards’ age and high-speed runs. This finding confirms that the propensity of strikers to cover distances at high intensity decreases over the years, revealing the advantage of having young forwards in the squad.

Important differences at the level of total distances covered and the speed of runs also exist between positions. Midfielders run the most (10.6km per match on average), while centre backs the least (9.2km). Wingers cover the greatest distance both in high intensity (932m) and when sprinting (211m). In these cases too, the lowest figures were measured for centre backs.

Issue number 351 of the CIES Football Observatory Weekly Post ranks clubs in 31 top divisions from UEFA member associations according to the percentage of domestic league minutes played by expatriates. The highest value overall was recorded for the Greek side Aris FC (98.4% of minutes), while Udinese Calcio (88.0%) tops the rankings for big-5 league clubs ahead of Chelsea FC (86.8%).

LOSC Lille, RB Leipzig and Atlético Madrid are the most foreign-oriented clubs in the other three major European championships, while Rangers FC tops the table in Scotland, Boavista FC in Portugal, Fatih Karagümrük in Turkey and SBV Vitesse in the Netherlands. The notion of expatriates refers to footballers who grew up in a different association from that of the employer club.

Only two teams out of the 474 surveyed did not field any expatriate player in domestic league games: the Ukrainian side FK Desna and the Basques of Athletic Club. The CIES Football Observatory is also happy to unveil that an improved version of the Demographic Atlas with current season’s data is now available here. Enjoy the tool!

Issue number 350 of the Weekly Post presents the estimated squad transfer values of the 98 teams in the big-5. The figures were calculated on the basis of the exclusive CIES Football Observatory algorithm. The two teams having invested the most to sign their current players, Manchester City and Manchester United, also are at the top of those with the highest estimated squad value.

The Manchester teams would potentially collect more than €1.2 billion in transfer indemnities if they decided put all their current squad members on the market. Chelsea completes the podium with an estimated squad value of €946 million. Barcelona heads the rankings in the Spanish Liga (€896M), Bayern Munich in the German Bundesliga (€890M), Paris St-Germain in the French Ligue 1 (€808M) and Juventus in the Italian Serie A (€618M).

The estimated transfer value of all English Premier League players totals €8.9 billion (€445M per team on average). For the other leagues of the big-5, these figures are €5.3 billion for the Spanish Liga (€263M per club), €4.5 billion for the German Bundesliga (€251M), €4.4 billion for the Italian Serie A (€222M) and €3.4 billion for the French Ligue 1 (€172M). The individual estimates for all big-5 league players are available here.

Issue number 349 of the CIES Football Observatory Weekly Post ranks teams from 72 top divisions worldwide according to the average age of line-ups fielded in the current season and the percentage of minutes played by footballers who did not yet celebrate their 21st birthday. Monaco played so far with the youngest line-ups in the five major European leagues (24.3 years), while Bayer Leverkusen fielded U21 players for the highest percentage of minutes (24%).

With 23% of domestic league minutes played by U21 footballers, Barcelona ranks second in the big-5 ahead of four French Ligue 1 teams (Nice, Rennes, Marseille and Reims). Arsenal fielded so far the youngest line-ups in the English Premier League (25.0 years), while Spezia did so in the Italian Serie A (24.8 years) and Real Sociedad in the Spanish Liga (25.5 years). At the opposite end for each big-5 league are Lazio (30.3), Elche (29.9), Burnley (29.3), Bochum (28.7) and Clermont Foot (28.0).

The Latvian side FK Metta fielded the youngest line-ups overall (20.2 years on average) and the Armenians of BKMA Yerevan top the table for the highest percentage of domestic league minutes played by U21 footballers (79%). On the contrary, 89 of the 1’041 teams surveyed did not field any U21 player, among which Wolfsburg, Newcastle United, Atlético Madrid, Juventus, West Ham United, Rangers FC, Trabzonspor, Mamelodi Sundowns, Columbus Crew and Al Hilal SFC.

The 348th edition of the CIES Football Observatory Weekly Post presents the forecasts for the 2021/22 season at the level of the five major European leagues. The statistical model used for this purpose includes the players’ experience, transfer fee investments to assemble squads, as well as each team’s performance in the last 365 days.

With respect to 2020/21, the only change from a champions perspective is supposed to take place in Spain, with Real Madrid finishing ahead of Atlético and Barcelona. In England, the top four would be the same as last season, with Tottenham fifth ahead of Everton. Norwich City, Watford and Newcastle United are the main candidates for relegation.

In Italy, Inter Milan would outrank Napoli and city rivals Milan AC, with Juventus only sixth. Wolfsburg are the most likely runners-up in the German Bundesliga, ahead of Borussia Dortmund and Bayer Leverkusen. In France, after Paris St-Germain, we would find the two Olympique (Marseille and Lyon in this order), while St-Etienne is a serious candidate for relegation.

Issue number 347 of the CIES Football Observatory Weekly Post ranks teams from 36 domestic leagues worldwide – 32 in Europe and 4 in the Americas – according to the number of passes made per match during current season as per data provided by our partners InStat. Paris St-Germain tops the rankings with an average of 738 passes.

In terms of the percentage of passes made in the opposite half, the Ukrainians of Shakhtar Donetsk are clearly at the top with an astonishing 68%, ahead of Manchester City (60%) and Ajax (57%). At the bottom of the rankings are Cosenza (22%) and two big-5 league teams: Norwich City and Elche (both 25%). As for the rate of accurate passes, the values vary between 92.6% for Paris St-Germain and Lazio, down to just 66.1% for Salernitana.

Regarding the four non-European leagues included in the sample, the highest figure for passes was measured for Flamengo (606, 87.7% of which accurate), while the lowest was observed for the Mexican side Atlético San Luis (336, 76.8%). Flamengo tops the table also for the proportion of passes in the opposite half alongside the Colombians of Deportes Quindío (50.3%). Another Brazilian team, Grêmio, complete the podium.

Issue number 346 of the Weekly Post presents the annual CIES Football Observatory analysis on big-5 league teams’ transfer fee spending to assemble their squads. With an estimated €1.08 billion invested to sign their current players (possible add-ons included), Manchester City remains at the top of the rankings. However, with respect to the start of the 2020/21 season, the gap with Manchester United went down by almost €140 million: from €192M to just about €58M.

The Manchester teams are the only ones to have spent over a billion euro in transfer indemnities to make up their current squads. Paris St-Germain complete the podium (€957M, + €69M with respect to the previous season), followed by Real Madrid (€787M, + €79M) and Chelsea (€780M, + €17M). Three further English Premier League teams (Liverpool, Arsenal and Tottenham), as well as Barcelona and Juventus, also paid more than €500 M in transfer fees to assemble their squads.

Per league, the average transfer expenditure per team to sign current squad members vary between €410 million for the English Premier League (with a minimum of about €87M for Norwich City) and €131M for both the French Ligue 1 (with a minimum for Clermont Foot) and the German Bundesliga (with a minimum for Bochum). The data for 2020/21 are available here.

The 67th edition of the CIES Football Observatory Monthly Report analyses from an economic perspective transfer operations carried out by big-5 league clubs during the last decade. It notably shows that the declining trend in investments after the health crisis has stopped. During the last transfer window, clubs from the five major European leagues spent 2% more than in the previous summer.

The study also shows that the pandemic has reinforced the domination of English Premier League clubs on the transfer market. The percentage of spending of the latter in comparison to the total big-5 league clubs’ transfer expenditure has increased from 35% between January 2012 and January 2020 to over 45% for the three post-COVID transfer windows.

The percentage of investments of the ten clubs having spent the most has also increased between these periods (from 33% to 35% per transfer window on average), as that of the ten most expensive transfers in comparison to the total (from 30% to 33%). All the indicators show a trend towards a concentration of spending from the richest clubs, in particular the wealthiest Premier League ones.

Six English teams are at the top of the rankings for the most negative post-pandemic net transfer spending, with Manchester United (-€217 million) ahead of Chelsea (-€205 M) and Arsenal (-€194 M). Since the COVID crisis, English top division clubs recorded a total deficit of almost two billion euro in transfer operations. Conversely, Spanish Liga teams registered a positive net balance (+€200 million).

Within the context of a general crisis, the English Premier League is the only competition where a majority of clubs invest massively on the transfer market. This allowed many teams from the other big-5 leagues, and, in a cascade effect, further down, to limit the impact of the health crisis and shows the importance of a global transfer system as it currently exists.

At the same time, the dependence of a growing number of clubs even within the wealthiest leagues on transfer incomes highlights the weakness of the current professional football economic system. The survival of more and more teams pivots indeed on the profits generated through the transfer of their best players. This situation is both financially dangerous and sportingly limiting.

FULL REPORT

Age categories in youth football are generally defined from January 1st onwards. Issue number 345 of the CIES Football Observatory Weekly Post analyses the month of birth of 43,938 players fielded in 2021 in 119 leagues worldwide. The study confirms the relative age effect, i.e. the advantage to be born early in the year to make a career.

In total, 31.2% of players in the sample are born in the first trimester of the year. In contrast, only 19.0% are born in the last trimester. Without relative age effect, these proportions should have been around 25%. Per national origin, the stronger concentration of footballers born in the first trimester was measured for the Chinese (43.6%). An over-representation was recorded for 64 of the 67 origins with at least 200 representatives in the sample.

The very low proportion of Japanese born in the first trimester (16.2%) is also the result of a relative age effect. Indeed, in Japan, youth categories start on April 1st. In England, players born in the first trimester are just slightly over-represented (27.1%) insofar as the reference date to define age categories is September 1st.

Issue number 344 of the CIES Football Observatory Weekly Post lists the 100 footballers worldwide who did not yet celebrate their 20th birthday and gained the most experience in official senior matches over the course of the year (minutes weighted by sporting strength of employer clubs or competitions played). The FC Barcelona’s gem Pedri González is clearly at the top of the table ahead of Manchester United’s Mason Greenwood and Ajax’s Ryan Gravenberch.

The Brazilian midfielder Matheus Martinelli (4th) is the best-ranked teenager playing outside of Europe, ahead of the 2003-born Uruguayan Fabricio Díaz from Liverpool Montevideo (7th) and his teammate at Fluminense Lucas Calegari (11th). Apart from Díaz, two other footballers born in 2003 are in the top 10 positions of the rankings: the Englishman Jude Bellingham (Borussia Dortmund) and the German Florian Wirtz (Bayer Leverkusen).

The Paraguayan Julio Enciso (Club Libertad) is the only footballer born in 2004 in the top 100 list. With 22 goals in official senior games in 2021, Benjamin Šeško (Salzburg and Liefering) is the top scorer among players listed. The Slovenian striker outranks the Czech national A-team player Adam Hložek (Sparta Praha), the Uruguayan Matías Arezo (River Plate Montevideo) and the German with Nigerian descent Karim Adeyemi (Salzburg).

With the start of a new and exciting season, the CIES Football Observatory is delighted to disclose some of the exclusive player physical data produced by our fresh partners SkillCorner. The French company has developed a unique and automated approach to track players from any football broadcast, whilst generating physical data and continuous XY tracking via specialised algorithms. With over 40 competitions covered worldwide, they position themselves as leaders in the market.

Issue number 343 of the CIES Football Observatory Weekly Post ranks 28 competitions according to the percentage of high intensity runs (>19.8 km/h) out of the total distance covered by players. The data refer to the last completed season. The English Premier League tops the table ahead of the Polish Ekstraklasa and the Spanish Liga. Conversely, the MLS, the Scottish Premiership and the Brazilian Serie A are at the bottom of the rankings.

At club level, Leeds United stands out with almost one tenth of the overall distance ran in high intensity. For the other four major European competitions, the greatest proportions were recorded for Athletic Club in Spain, Olympique Lyonnais in France, Juventus in Italy and Wolfsburg in Germany. With regard to overall distance covered, the leaders are Barcelona, Napoli, Leeds United (again), Hoffenheim and Angers.

The 66th CIES Football Observatory Monthly Report studies the changes occurred during the past five years in ten of the principal women’s leagues worldwide from the aspect of the players’ age, the percentage of expatriate footballers, as well as that of full international players. It notably shows the growing influence of the major European men’s clubs in the sphere of women’s football.

The fresh capital invested has notably stimulated the international mobility of women footballers. In the ten leagues studied, the percentage of expatriates has increased from 21.6% in 2017 to a record 33.0% in 2021. The increasing dominance of the traditionally men’s clubs in women’s football is clearly visible when looking at teams with the greatest number of full internationals. In the first 15 places are 14 teams whose male counterparts play in the five major European leagues.

The development of women’s football in Europe has encouraged more and more players from the best women’s football nation, the United States, to emigrate. In June 2021, with 87 citizens abroad in the championships studied, the United States were by far the most represented expatriate origin, ahead of Sweden (39 players) and Canada (37 players).

How much did players selected for the upcoming Euro 2021 play since the COVID break in 2020? Issue number 342 of the CIES Football Observatory Weekly Post ranks the footballers according to minutes played in official games for both clubs and national teams (A-teams and U21) since the 16th May 2020. With 6,472 minutes and 81 matches, Manchester United’s and Portugal Bruno Fernandes heads the table.

Manchester United’s and England centre back Harry Maguire ranks second (6’449 minutes, 72 official games) ahead of Milan AC’s and Italy goalkeeper Gianluigi Donnarumma (6’420 minutes, 71 matches). Four other goalkeepers are in the top 10 (Kasper Schmeichel, Hugo Lloris, Manuel Neuer and Thibaut Courtois), alongside Rúben Dias (Manchester City and Portugal), Jules Koundé (Sevilla and France), as well as Andrew Robertson (Liverpool and Scotland).

Per national team, the three top values of minutes per player were recorded for England (4,442), Portugal (4,258) and Germany (4’214). At the opposite end, we find North Macedonia (2,595), Wales (2’704) and Slovakia (2,738). With only 209 minutes in official games since the COVID break, the 19-year-old Welshman Rubin Colwill from Cardiff City played the least minutes among all footballers selected for the Euro 2021.

Three English talents are at the top of the biannual ranking of the greatest estimated transfer values for big-5 league players. According to the CIES Football Observatory algorithm, €190 million should be proposed to eventually convince Manchester City releasing Phil Foden. Two Manchester United’s players complete the podium: Mason Greenwood (€178 M) and the former leader Marcus Rashford (€159 M). The top 100 is available in the 341st Weekly Post.

Erling Haaland has the top estimated transfer value for players outside of the English Premier League. With respect to fees paid in the past, an investment of €155 M would be necessary to sign the Norwegian striker. With only one year of contract remaining, Kylian Mbappé (€118 M) is only 12th. Only three of the 20 big-5 league footballers with an estimated transfer value of more than €100 M are over 25 years of age: Bruno Fernandes, Timo Werner and Bernardo Silva.

Ederson Moraes (€62M) has the greatest estimated value for goalkeepers. His teammate at Manchester City Ruben Días (€114 M) tops the table for centre backs. Alphonso Davies (€131 M) from Bayern Munich is at the top for full backs and no other defensive midfielder has an estimated value as high as Barcelona’s Frenkie de Jong (€138 M). Transfer value intervals for all big-5 league footballers are available on the CIES Football Observatory website.

National teams with players active in the most competitive clubs have greater chances to win trophies. Issue number 340 of the CIES Football Observatory Weekly Post compares selections qualified from the perspective of the average sporting level of the teams of employment of players in squads. France tops the table ahead of Germany and Spain.

The Post also presents the average number of domestic league minutes played since September 1st 2020 by footballers from the 24 teams qualified. The maximal value was recorded for players of the English team (2,496 minutes), while the lowest one was measured for Ukraine (on average only 1,390 domestic league minutes per player).

With an average age of 24.9 years on June 1st, Turkey is the youngest team. It outranks England (25.2 years) and Wales (25.5 years). At the opposite end we find Sweden (29.2 years), followed by Belgium (29.1 years) and Slovakia (28.2 years). Born on the 16th October 2003, the Polish Kacper Kozlowski is the youngest player, while the Dutch goalkeeper Maarten Stekelenburg (22.09.1982) is the oldest.

With the five major European leagues ended, issue number 339 of the CIES Football Observatory Weekly Post presents the best line-ups for each championship. Players were selected according to the CIES performance index developed using data from OptaPro. Only footballers fielded for at least two thirds of domestic league minutes were included in the line-ups.

The formation selected for the English Premier League is a 4-2-1-3, with Bruno Fernandes as an attacking midfielder behind Harry Kane and besides Raheem Sterling and Mason Mount. The defense is made up of three Manchester City players (Ederson Moraes, Rubén Dias and João Cancelo), plus Victor Lindelöf and Andrew Robertson, with Rodri Hernández and Granit Xhaka as holding midfielders.

Some outstanding but not yet very known players are included in the line-ups for the remaining leagues. We notably find Ridle Baku (Wolfsburg) as right full-back in the German Bundesliga’s best 11, Aurélien Tchouaméni (Monaco), Farid Boulaya (Metz) and Romain Faivre (Stade Brestois) in the French Ligue 1 selection, Domenico Berardi (Sassuolo) in Italy and Javi Galan (Huesca) in Spain.

How frequently are teams fouling their opponents across Europe? Issue number 338 of the CIES Football Observatory Weekly Post answers this question using the data provided by In Stat. At the level of the five major European leagues, the lowest foul frequency was measured for Arsenal (one foul every 10’44”), while Getafe is at the bottom end of the table (one foul every 5’44”).

Apart from Getafe, the highest foul frequency per big-5 league was measured for Hellas Verona (5’54”), FSV Mainz (6’30”), AS St-Etienne (7’10”) and Fulham FC (7’48”). Conversely, apart from Arsenal, the following teams committed the least fouls per minute: FC Barcelona (10’29”), Bayern Munich (10’19”), SSC Napoli (9’37”) and Nîmes Olympique (9’13”).

Out of all the 30 leagues surveyed, the extreme values were measured for FC Zenit (one foul every 12’34”) at one end and for two Greek teams at the other: PAS Giannina and Volos NFC (one foul every 4’51”). Eleven Greek top division clubs are among the 20 ones committing the most fouls per minute. Conversely, eight Russian teams are among the 20 with the lowest foul frequency.

The CIES Football Observatory just disclosed a report analysing the presence of expatriate footballers in 145 leagues from 96 national associations worldwide. With 1,287 players abroad, Brazil tops the rankings for exporting countries. However, while the number of Brazilians went down by 14 compared to 2020, that of the second most represented nation abroad, France, increased by 124 to reach a new record high of 946.

On the 1st of May 2021, despite the pandemic, the number of expatriates grew by almost 5% in comparison to the same date in 2020: from 13,025 to 13,664. This increase in difficult circumstances confirms that the internationalisation of the footballers’ labour market is a well-established process. Expatriates represent 21.3% of players surveyed: from 26.4% in the domestic leagues of UEFA member associations down to only 8.9% in those of the CONMEBOL.

Overall, more than a fifth of expatriate players originate from Brazil, France and Argentina (21.4%). If we take the number of expatriates in comparison to the population resident in the country of origin, Iceland tops the rankings. There is one expatriate Icelandic footballer for every 5,584 inhabitants of the island. Montenegro is second (one expatriate for every 6,759 inhabitants), ahead of Croatia (10,792), Uruguay (11,889) and Serbia (15,742).

Issue number 337 of the CIES Football Observatory Weekly Post reveals the employment rate of club-trained footballers (i.e. those having been for at least three seasons between the ages of 15 and 21 in their employer club) in teams from 27 top divisions of UEFA member associations. The highest percentage of minutes by club-trained players overall was recorded for the Slovakian side MŠK Žilina (61.5%), while RC Celta de Vigo (49.0%) has the greatest figure for big-5 league teams.

Home-grown footballers played a majority of domestic league minutes also at Dynamo Kyiv (60.2%), Sigma Olomouc (52.0%) and FC Slovácko (51.1%). At the level of the five major European championships, the highest employment rates after Celta Vigo were observed for two Basque sides: Real Sociedad (48.5%) and Athletic Club (40.6%). AS St-Étienne (35.0%), Brighton & Hove Albion FC (30.1%), FSV Mainz (25.0%) and Genoa CFC (20.9%) top the table in the remaining big-5 leagues.

Per championship, the values stretch from 26.8% in Slovenia to 4.7% in Portugal. Among the big-5 leagues, only the Spanish Liga (15.7%) is above the European average (13.2%), with a minimum of 5.0% in the Italian Serie A. English teams (12.6%) relied more on club-trained footballers than French (11.8%) and German (10.5%) ones. The CIES Football Observatory Demographic Atlas presents more exclusive statistics on the composition of squads across Europe.

Issue number 336 of the CIES Football Observatory Weekly Post presents the index developed by the sports data company InStat to assess the performance of football players. This metric considers the technical gestures achieved by players, their playing time, as well as the level of the competitions in which matches were played. For footballers with more than 1,000 domestic league minutes this season, Lionel Messi (405) outranks Neymar Júnior (381) and Robert Lewandowski (371).

Manchester City’s full back João Cancelo (368) head the table in the English Premier League ahead of teammates Rodri Hernández, Kevin de Bruyne and Riyad Mahrez. At fifth position is Jesse Lingard (West Ham, on loan from Manchester United). Players from five different teams are at the top five positions of the Serie A rankings: Lorenzo Insigne (Napoli), Achraf Hakimi (Inter), Cristiano Ronaldo (Juventus), Théo Hernández (Milan) and Domenico Berardi (Sassuolo).

The youngest players heading the table in their respective league are 21-year-olds Noa Lang (Club Brugge) in Belgium and Fabio Parisi (Empoli) in the Italian Serie B, as well as 22-year-olds Patson Daka (RB Salzburg) in Austria, Olimpiu Moru?an (FCSB) in Romania and Denys Popov (Dynamo Kyiv) in Ukraine. The InStat Index for almost 10,000 players from 32 leagues of UEFA member countries is available in exclusivity and for free here.

While player mobility has increased in recent years, squad stability remains a key success factor in football. Issue number 335 of the CIES Football Observatory Weekly Post highlights the footballers among current squad members having played the most domestic league matches during the last ten years for 540 teams from 35 top divisions worldwide. Sebastián Viera holds the record figure with 395 championship games for Junior de Barranquilla (Colombia).

At European level, Leicester City’s goalkeeper Kasper Schmeichel (372 domestic league games) outranks FC Barcelona’s Lionel Messi (340) and Manchester United David de Gea (337). Karim Benzema is the current Real Madrid squad member who played the most championship games for the Merengues during the last decade (322), César Azpilicueta (292) for Chelsea, Sergio Agüero (272) for Manchester City and Marco Verratti (221) for Paris St-Germain.

At league level, the average number of games over the last ten years for the most used player per team varies between 263 in the English Premier League and 125 in the Australian A-League. All of the five major European championships are in the top eight position of the rankings. This result shows that stability goes hand in hand with money and that player mobility is exacerbated where clubs lack resources.

The 334th edition of the Weekly Post presents the squad transfer value for the 98 teams in the five major European leagues. The estimated value for players loaned to other big-5 league teams was computed for the clubs of belonging, while that of players on loan outside of the top five European championships is not considered. The estimates were calculated through the CIES Football Observatory transfer value algorithm.

Current Premier League leaders and Champions League semifinalists Manchester City are at the top of the table with a total squad value of €1.30 billion. Pep Guardiola’s team outranks two other English clubs: Manchester United (€1.16 billion) and Chelsea FC (€1.11 billion). FC Barcelona ranks first for non-English teams with an estimated squad value of €991 M, while Juventus FC (€829 M), Bayern Munich (€777 M) and Paris St-Germain (€603 M) head the rankings for the three other big-5 leagues.

The average squad value per club is €474 M for the English Premier League, €281 M for both the Spanish Liga and the German Bundesliga, €276 M for the Italian Serie A and €174 M for the French Ligue 1. The transfer value intervals for all big-5 league players are available for free here. The estimates refer to the situation on the 1st April. Updated figures and projections according to predefined scenarios are available on a consultancy basis.

The 64th CIES Football Observatory Monthly Report crunched InStat data to unveil the effective playing time and other indicators regarding the fluidity of matches in 37 European competitions. It notably shows that the fluidity of the game depends on geographical and cultural logics. The proportion of stoppage time due to fouls in comparison to the total length of matches, for example, varies between just over 10% in the Netherlands up to almost 20% in Greece.

The number of fouls and time lost due to them tends to be higher in Southern and Eastern European leagues than in the championships from the North and West of the continent. The Turkish Süper Lig stands out as the competition in which the time taken to restart play after a foul is the longest: about 35” of stoppage time as opposed to 30” for all leagues. It is also in Turkey that referees add the most extra time: almost 9 minutes on average compared to 6’14” for all competitions surveyed.

The average effective playing time is 61%. It goes from 67% in Israel down to 56% in the Spanish Segunda División. The study also reveals the absence of correlation between the effective playing time and the total length of matches. This shows that the level of fluidity in the game is not taken into account by referees when it comes to adding extra time. This could encourage players of teams in difficulty, or having gained an advantage, to disrupt the rhythm of the game, knowing that the stoppage time has not much influence on the number of minutes added.

Issue number 333 of the CIES Football Observatory Weekly Post presents the percentage of domestic league minutes by footballers who had not yet turned 21 at the time of the matches played this season for 999 clubs from 71 top divisions that are currently running worldwide. The highest percentages were recorded for the Danish side FC Nordsjælland (48.9%) among the 30 major European competitions and the Singaporean team Young Lions (47.1%) for the clubs surveyed outside of Europe.

At big-5 league level, the highest figures were measured for Borussia Dortmund (28.5%), followed by three French Ligue 1 teams: OGC Nice (24.3%), AS Monaco (24.1%) and Stade Rennais (20.7%). The greatest proportion of minutes in the other major championships were registered for Wolverhampton (16.2%), FC Barcelona (15.0%) and Hellas Verona (11.7%). At the opposite end, eight teams did not field any U21 player, among which Tottenham and Inter.

The highest percentage overall was observed for FK Metta (88.0%), the team of the Riga’s University of Latvia. U21 footballers played a majority of minutes in two other Latvian top division teams: Valmiera FC and BFC Daugavpils. Ecuador’s club Independiente del Valle (34.3%) and Alger-based Paradou AC (27.8%) lead the table for America and Africa respectively. The average age on the pitch for clubs in the 31 main European leagues are available in the CIES Football Observatory Demographic Atlas.

Issue number 332 of the CIES Football Observatory Weekly Post compares 72 top division leagues worldwide from the perspective of the percentage of matches in which a team won by at least three goals. The lowest proportion of uneven fixtures was recorded in the Colombian Categoría Primera A: just 5 out of 126 (4.0%). At the opposite end of the table is the Solomon Islands top division: 41 uneven games out of 110 (37.3%).

For the UEFA member associations surveyed, the percentages vary between 8.8% in the Albanian Superliga and 31.2% for the Moldovian Divizia Na?ional?. More than one fifth of both the Austrian (23.5%) and German Bundesliga (20.9%) matches ended with at least a three-goal gap between opponent teams. These are much higher percentages than the average measured at the level of the 72 competitions included in the analysis (14.5%).

The Spanish Liga (11.4%) is the only league among the five major European ones where the proportion of uneven fixtures was so far lower than the global average. The contrary holds true for the French Ligue 1 (15.0%), the English Premier League (17.2%) and the Italian Serie A (17.7%). The Arabian Gulf League in the United Arab Emirates (22.2%) and the Stars League in Qatar (21.7%) stand also out as particularly uneven competitions.

The CIES Football Observatory has developed a unique methodology to compare the performance of players irrespective of their position. Issue number 331 of the Weekly Post highlights the outfield footballers with the highest score for domestic league matches played since the 1st of January 2021 for each of the 98 big-5 league clubs. Only players fielded for at least two thirds of minutes during this period are included in the rankings.

The greatest value overall was recorded for Lionel Messi: 92.5 out of 100! Eliminated from the Champions League, the Argentinean striker and FC Barcelona can now focus on the Liga. However, the departure of Luis Suárez will be a major obstacle to the title race. The Uruguayan has indeed the top performance score (84.3) at Atlético Madrid, while Toni Kroos (87.5) leads the table for Real Madrid ahead of Karim Benzema (85.3).

In the other four main European leagues, the highest CIES FO performance index values were registered for Robert Lewandowski in the Bundesliga (89.5), Cristiano Ronaldo in the Serie A (89.3), Guillermo Maripán (86.3) in the Ligue 1 and Jorginho Frello in the Premier League (89.4). In the latter competition, Chelsea’s midfielder outranks Rubén Dias (89.4), Wilfred Ndidi (85.2) and Luke Shaw (83.4). The technical profiles of all big-5 league players are available here.

The CIES Football Observatory has developed a powerful algorithm to assess the transfer value of professional football players on a scientific basis. Issue number 330 of the Weekly Post presents the top valued footballer for each of the 98 teams from the five major European leagues, as well as the percentage that the value of the most expensive player represents out of the total estimated transfer value of his owner club.

With an estimated transfer value of more than €150M, Marcus Rashford is the main asset of Manchester United. The Englishman represents almost 15% of the entire Manchester United’s estimated transfer value. This percentage rises above 20% concerning Erling Haaland and Borussia Dortmund, while it is about 10% for Phil Foden and Manchester City, and just below that proportion for Vinícius Júnior and Real Madrid.

The lowest dependance on the top valued player was recorded for an Italian Serie A team. With an estimated transfer value between €30 and €40M, Italian national A-team centre back Gianluca Mancini represents 8,7% of the total estimated AS Rome’s squad value. At the opposite end of the table is SD Eibar, where Edu Expósito (€15-20M) represents almost 40% of the total squad value. The estimated transfer value intervals for all big-5 league players are accessible for free here.

Major teams are built up over a period of years. The 63rd CIES Football Observatory Monthly Report presents an innovative approach to comparatively assess the sustainability of squads based on three elements: players’ age, the length of their stay in the employer club and the duration of their contracts. According to these criteria, Manchester United currently has the most sustainable squad among the 98 big-5 league clubs.

Manchester United fans can thus be confident in the ability of their team to qualify without too much difficulty for the group stage of the Champions League over the next seasons, and eventually lift again the Premier League trophy. Ranked just behind Manchester United despite having far fewer financial resources, the Basque clubs Real Sociedad and Athletic Club constitute perfect examples of sustainable squad management. Conversely, Genoa is a perfect example of short-term planning.

While football is not an exact science, data analysis can be an important tool with which to optimise performance. The sustainable squad management rating is not just a descriptive tool allowing the comparison of strategies pursued by teams in the past, which is interesting in itself, but also an instrument to steer future policies so as to increase the chances of success.

Issue number 329 of the CIES Football Observatory Weekly Post highlights footballers having won the highest percentage of domestic league matches in which they participated as starting 11 players since the 15th March 2020. The sample covers 42 top divisions worldwide. It only includes footballers who started at least 20 games in their current league (regular season or play-off matches).

The greatest success rate overall was recorded for Red Star Belgrade’s Milan Gaji? (21 wins out of 22 fixtures), while Bayern Munich’s Serge Gnabry leads the table for the big-5 (21/23). The most successful post-COVID players in the other four major European championships are Bernardo Silva (Manchester City) for the Premier League, Mario Hermoso (Atlético de Madrid) for the Liga, Jonathan David (LOSC) for Ligue 1 and Alexis Saelemaekers (Milan) for Serie A.

At the opposite end of the table, Bastian Oczipka (Schalke 04) did not win any of the 23 German Bundesliga matches played as a starting 11 player. The lowest success rates in the other major European leagues were observed for Sam Johnstone (West Bromwich Albion, 2/27) in England, Anaitz Arbilla (Eibar, 2/21) in Spain, Simone Iacoponi (Parma, 2/22) in Italy and Bruno Ecuélé Manga (Dijon, 2/28) in France.

Issue number 328 of the CIES Football Observatory Weekly Post highlights the most promising youngsters worldwide according to the capital experience approach. The latter weights domestic league minutes played by footballers with the sporting level of their teams of employment on a global level. The greatest capital experience since January 1st 2020 for players born in the 2000s was calculated for Borussia Dortmund’s winger Jadon Sancho.

Two other German Bundesliga players complete the podium: Bayern Munich’s Alphonso Davies and Sancho’s teammate at Borussia Dortmund Erling Haaland. Two Englishmen are at the top of the table for 2001-born footballers: Bukayo Saka (Arsenal) and Mason Greenwood (Manchester United). This suggests good prospects for the English national team in the coming years. At the top of the rankings for players born in 2002 is Barcelona’s Pedri González ahead of St. Gallen’s Leonidas Stergiou.

For footballers born in 2003 or after, the highest experience capital gained since a bit more than one year was recorded for Bayer Leverkusen’s Florian Wirtz. At second position is another German Bundesliga player eligible for England, Borussia Dortmund’s Jude Bellingham, while two additional Englishmen are in the top six positions: Harvey Elliott (Blackburn, on loan from Liverpool) and Jamal Musiala (Bayern Munich). Should the latter finally opt for England to become world champion?

Issue number 327 of the CIES Football Observatory Weekly Post crunches the InStat data on the direction of passes made during current season by more than 500 teams from 31 European leagues. No club made so far a greater percentage of passes backwards than current Premier League leaders Manchester City: 41.6%. This reflects the emphasis put on possession by Guardiola’s side.

Six other teams from the five major European leagues are in the top 10 positions of the table: Chelsea (4th), Arsenal (5th), Sassuolo (7th), Barcelona (8th), Paris St-Germain (9th) and Real Madrid (10th). The only exceptions are Shakhtar Donetsk (2nd), Lokomotiv Moscow (3rd) and Ferencvaros (6th). Conversely, with only 24.0% of passes backwards, the bottom-ranked Championship team Wycombe Wanderers are at the bottom of this table too.

The more competitive the leagues, the higher the percentage of backward passes. The greatest proportion of passes backwards was recorded for the English Premier League (36.5%). The time for kick and rush is definitely over. This is not that much the case for less performing championships. The lowest percentage of backward passes was observed in the Austrian Bundesliga (29.6%). More statistics at team level are to be found in the CIES Football Observatory Performance Atlas.

Who are the U23 players with the best credentials to make soon their national A-team debut with one of the nations in the 20 top positions of the FIFA rankings? Issue number 326 of the CIES Football Observatory Weekly Post answers this question by considering the experience level that eligible footballers have accumulated during the last year (minutes weighted by sporting level of employment teams or competitions played).

Jules Koundé is the best positioned U23 footballer to celebrate soon his first cap with the reigning world champions of France. The Sevilla’s centre back outranks Moussa Diaby (Bayer Leverkusen) and Boubacar Kamara (Olympique de Marseille). The three U23 uncapped players eligible for England with the greatest experience level over the last year are James Justin (Leicester City), Dwight McNeil (Burnley) and Aaron Ramsdale (Sheffield United).

For the other top nations, Arnaud Bodart (Standard Liège) leads the table for Belgium, Roger Ibañez for Brazil (or eventually Uruguay), Pedro “Pote” Gonçalves (Sporting CP) for Portugal, Marc Cucurella (Getafe) for Spain, Cristian Romero (Atalanta) for Argentina, Gabriele Zappa (Cagliari) for Italy, Florian Wirtz (Bayer Leverkusen) for Germany and Érick Sánchez (Pachuca) for Mexico. The top 20s player for the 20 best-ranked nations are available here.

The CIES Football Observatory just disclosed its second analysis on the demographic profile of players and teams in four Latin American top divisions: Brazil, Argentina, Mexico and Chili. The study notably reveals that the COVID-19 pandemic led to a decrease in the average age of players fielded and brought to an increase in the part of club-trained footballers in squads.

The most important changes were recorded in the Argentinean top division, where the percentage of club-trained players has gone up from 22.6% to 34.1% (+11.5%). As a comparison, the percentage of players from clubs’ youth academies among all footballers fielded in domestic league matches is 19.0% in Chile (+1.2%), 18.5% in Brazil (+3.8%) and 13.5% in Mexico (+0.2%). CA Banfield holds the record for the highest percentage of minutes played by club-trained footballers (76.1%).

The study also reveals that CA Boca Juniors is by far the team having trained the greatest number of players present in the four leagues studied: 48, of whom only seven are still at the Buenos Aires club. With 38 players trained, Santos FC et CA Lanús are the second biggest training clubs, just ahead of the Chileans of Universidad Católica and the Argentineans of CA River Plate (37 players trained in both cases). The full analysis is available in the 62th CIES Football Observatory Monthly Report.

Issue number 325 of the CIES Football Observatory Weekly Post presents the points projected at the end of the season for teams from 22 leagues across Europe. The projection was calculated using a statistical model taking into account shots on target and from the box attempted or conceded, ball possession, as well as teams’ own passes and those of opponents in the opposite third of the pitch.

According to this projection, Inter Milan would be crowned Italian champions 11 years after their last title, ahead of Milan AC (+2 points) and Juventus (+3). The biggest surprise would come from France, where Olympique Lyonnais would total 82 points, one more than Paris St-Germain. In Spain, Atlético Madrid would have to fight up until the end of the season against Barcelona (+3 points), while Bayern Munich in Germany should have a more relaxing season end.

In the Premier League, Manchester City would outrank Manchester United by 14 points, with Liverpool at 3rd position ahead of Chelsea for the last Champions League spot. WBA would finish last, behind Sheffield United and Burnley, while Fulham would avoid relegation. Brentford and Norwich would total 89 points in the Championship, eight more than Swansea. More stats for teams from 35 European leagues are to be found in the CIES Football Observatory Performance Atlas powered by InStat data.

During the last ten transfer windows, Manchester City total the most negative net transfer spending among current big-5 league clubs (-€631M) ahead of city rivals Manchester United (-€586M). Two French Ligue 1 clubs are at the opposite end of the table: LOSC Lille (+€191M) and Olympique Lyonnais (+151M). Issue number 324 of the CIES Football Observatory Weekly Post presents the data for each club.

The third most negative transfer balance since the summer 2015 was recorded for FC Barcelona (-€471M). Beyond the much-debated Lionel Messi’s great salary, this heavily contributed to increase the Catalan club’s debt. Two other teams with recurrent operating deficits, Inter and Milan AC, also are among the ten big-5 league clubs with the most negative net transfer spending during the period analysed: -€386M for Inter and -€211M for Milan.

No English Premier League team has a positive transfer balance during the period considered. The least negative net spending was recorded for Southampton (-€50M), ahead of West Bromwich Albion (-€73M) and Newcastle United (-€77M). The most positive balances in Italy, Germany and Spain were recorded for Atalanta BC (+€133M), Hoffenheim (+€87M) and Valencia (+€67 M). The data comes from the CIES Observatory own research using data published by clubs or reported by media.

Issue number 323 of the CIES Football Observatory Weekly Post ranks teams from 31 European leagues according to the number of shots per goal as per the data provided by InStat. The most clinical team overall is Hamburger SV (one goal every 4.7 shots), followed by Olympiacos and Bayern Munich. At the opposite end, the highest figure was recorded for Belenenses (one goal every 20.5 shots).

At the level of the five major European championships, the most clinical teams after Bayern so far this season are Spanish leaders Atlético Madrid (one goal every 5.4 shots) and Union Berlin (5.7). Inter Milan (6.0) is the most clinical team in the Italian Serie A, Leicester City in the English Premier League (6.0) and AS Monaco in the French Ligue 1 (6.2).

The study also presents the percentage of shots taken from the opponent box and the average distance of shots. For the former indicator, the proportions vary between from 70% for Dinamo Kyiv to only 41% for the Croatian side HNK Šibenik. For the average shot distance, the figures range from 14.2 meters for Viktoria Plze? to 22.0 meters for the Serbs of FK Rad.
