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.

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.

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.

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.
