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.
