Issue number 369 of the CIES Football Observatory Weekly Post ranks teams from 50 top divisions worldwide according to the number of players fielded in domestic league games during the last 365 days. For current big-5 league teams, the values stretch from an eye-staggering 55 players for Genoa down to only 27 for West Ham United.

The highest figure overall was recorded for Deportivo Pasto. The Colombians fielded up to 70 players in the 40 domestic league matches played during the last year. They outrank the Romanians of Dinamo Bucuresti and the Welsh of Cefn Druids (both 63 players). The four highest figures in the big-5 were all recorded for Italian Serie A teams: Genoa (55), Salernitana (53), Venezia (47) and Spezia (46).

The record figures for UEFA Champions League teams are much lower: 38 players for Paris St-Germain and 36 for Juventus. LOSC Lille and Manchester City are at the opposite end: 28 players for both. By league, the average values per club vary between 31 players in England and Moldavia, up to a maximum of 47 in Colombia.

The main findings will be published online on our website and social media channels (Facebook, Twitter, Instagram). A report outlining the main results of a previous survey on professional football is available here.

Issue number 368 of the CIES Football Observatory Weekly Post crunched the InStat data on goal scoring chances and effective playing time for 36 European leagues since 2018/19 (or 2018) to determine the level of “game openness”. The findings show that clubs in leagues from the North/West part of the continent tend to play more openly than those from the South/East.

With an average of 11.7 chances and 63’21” effective time per match, the Dutch Eredivisie recorded the highest Game Openness Index, ahead of the German Bundesliga and the Belgian Pro League. At the opposite end is the Spanish Segunda División with just 8.7 chances and 55’06” of effective time. The Greek Super League and the Romanian Liga I also are at the bottom three of the rankings.

On average, the effective playing time of matches in the 36 leagues survey is just above 59 minutes: from 63’21” in the Netherlands to 54’55” in the Czech Republic. Teams create on average 10.2 goal scoring chances per match: from 11.9 in the German Bundesliga to 8.7 in both the Spanish second division and the Greek top one.

Issue number 367 of the CIES Football Observatory Weekly Post ranks current big-5 league clubs according to their net spending on transfer operations concluded over the last ten seasons. Manchester United tops the table with a negative balance of more than one billion euro, ahead of Manchester City and Paris St-Germain. Fourteen English clubs are in the top 20 of clubs with the most negative net transfer spending.

LOSC Lille clubs stands out at the opposite end with a positive transfer balance of €349 million over the last decade. The French side outranks league rivals Olympique Lyonnais and three Italian Serie A teams: Genoa, Udinese and Atalanta. The top three of current big-5 league clubs having generated the most incomes from transfers since 2012/13 are Chelsea, Monaco and Atlético Madrid. In total, 52 out 98 clubs have a positive net spending. This ratio is one (Brentford) out of 20 for Premier League teams.

Gathered with the greatest care through the cross-checking of all possible sources, whether official or unofficial, the data includes eventual add-on fees included in the deals, regardless of their actual payment. Within the limits of available information, incomes deriving from sell-on fees are also taken into account.

Issue number 366 of the CIES Football Observatory Weekly Post presents the 100 players born in 2002 or after active in 31 European leagues outside of the big-5 with the highest InStat Index. The latter takes into consideration footballers’ pitch production depending on position played (centre back, winger, etc.) and the general level of the matches in which they participated.

The greatest score overall was recorded for AFC Ajax’s Ryan Gravenberch. Among midfielders, the Dutch talent ranks ahead Arsen Zakharyan (Dinamo Moscow) and Fábio Carvalho (Fulham). Running out contract, the latter is being courted by several major teams. The highest InStat Index for full backs was recorded for another AFC Ajax player who is attracting interest from clubs in the big-5: the 19-year-old Devyne Rensch.

The best score for other positions were measured for Oliver Dovin (Hammarby) among goalkeepers, Ilya Zabarnyi (Dynamo Kiev for centre backs and Jakub Kaminski (Lech Poznan) among forwards. Akinkunmi Amoo (Hammarby) and Sebastiano Esposito (Basel, on loan from Inter) complete the podium for strikers. The InStat Index for players from 36 European leagues is accessible for free in this exclusive tool. More information is available on demand.

For the first time, the CIES Football Observatory research team has compiled a study comparing from a demographic perspective the five major European leagues with ten additional competitions located in three other continents: America (Argentina, Brazil, Chile, Colombia, Mexico, United States and Canada), Asia (South Korea, Japan, China), as well as Oceania (Australia and New Zealand). All the data is available for free in the 71st edition of the Monthly Report.

The study notably reveals that, during the second semester 2021, club-trained footballers played almost twice in non-European teams than in European ones: 19.4% of total domestic league minutes compared to 11.7%. However, for the MLS in the USA and Canada, players from clubs’ youth academies only played 9.2% of minutes. This is the second lowest figure after that recorded in the Italian Serie A (7.4%). The Argentinean Liga Profesional is at the opposite end with a record high of 29.4% of minutes played by club-trained footballers.

Boca Juniors stands out as the biggest training club with 78 footballers from its youth academy fielded by the 286 teams surveyed, 18 more than city rivals River Plate. The Colombians of Deportivo Cali (56 players) complete the podium of the most productive training teams, ahead of FC Barcelona (50), São Paulo (49) and Colo Colo (48). The 365th CIES Football Observatory Weekly Post presents the top 100 list of clubs having trained the most players fielded in the 15 leagues analysed.
