Issue number 170 of the CIES Football Observatory Weekly Post presents the number of players fielded in domestic league matches from July 1st 2016 onwards by clubs in 31 top division leagues of UEFA member associations. The record values were observed for the Finnish champions Mariehamn (17 players) and the Croatian side RNK Split (37 players).

At big-5 league level, the teams having fielded the most players are not in the top positions of the table in their respective league: Werder Bremen (30 players, 14th), Osasuna (29, 20th) or Lorient (28, 20th). Conversely, Chelsea (1st), Bayern Munich (1st), RB Leipzig (2nd) and Nice (1st) are among the clubs having used the least footballers.

This analysis shows that quality is the key criterion to assemble successful squads. It also highlights that too much turnover does not allow teams to significantly improve their performance standards. The data for all teams in the 31 top division leagues surveyed are available in the CIES Football Observatory Digital Atlas.

We wish you a happy new year, with plenty of exciting football matches and statistics!

Issue number 20 of the CIES Football Observatory Monthly Report investigates the international mobility of minors in football. It reveals that the number of players who left their country before to turn 18 has reached a new record high in 2016. English clubs are by far the most active in the international recruitment of minors.

Almost 600 footballers having moved abroad before the age of 18 currently play in 31 top division leagues of UEFA member associations. For almost one third of them, the first foreign destination was England. The second biggest importing country for minor players is Italy. In terms of origins, the most represented nations are Belgium, Sweden, France, Hungary and Austria.

As fully developed in the book Slow foot (only available in French), the Report indicates that “players having left their country under the age of 18 have, on average, less rewarding careers than footballers who left later with more experience under their belt”. The authors claim that “the premature international migration of inexperienced players poses serious risks for both the footballers concerned and the teams recruiting them”.

According to Drs. Raffaele Poli, Loïc Ravenel and Roger Besson, “unfortunately, in spite of all sporting logic, and in an overly speculative context where numerous actors make their living out of player transfers, the international flow of minors increases with each year”. Far from being solved, the issue of the transfers of minors in professional football will certainly still receive considerable attention in the years to come.

Issue number 168 of the CIES Football Observatory Weekly Post presents the 100 footballers born on or after January 1st 1997 who played so far the highest percentage of minutes in 31 top division European leagues. Among the four players fielded for 100% of minutes are three goalkeepers: Gianluigi Donnarumma (Milan), Alban Lafont (Toulouse) and Adam Jakubech (Spartak Trnava).

The only outfield footballer who played all minutes between July 1st and November 30th is the Dutch centre back Justin Hoogma (Heracles). The top ranked big-5 league outfield centre back is another very promising centre back: Malang Sarr (Nice). The most represented leagues in the top 100 are the Slovakian (9 players), the Dutch (8 players) and the French ones (7 players).

In addition to Lafont, Donnarumma and Sarr, only two other players born in 1999 are in the top 100 of the rankings: Petko Hristov (Slavia Sofia) and Alexander Isak (AIK Solna). In addition to Hoogma, 21 other footballers born in 1998 are among the 100 most fielded U20 players. The remaining footballers are born in 1997.
