The presence of club-trained footballers greatly varies throughout Europe. Issue number 164 of the CIES Football Observatory Weekly Post ranks 31 top division championships of UEFA member associations according to the percentage of club-trained players in squads.

In three countries, footballers who have been for at least three seasons between 15 and 21 years of age in their employer club account for less than 10% of squad members: Turkey (6.9%), Portugal (9.6%) and Cyprus (9.6%). At the opposite end of the table, the percentage of club-trained players is over 30% in Slovakia (31.5%) and Ukraine (30.6%).

The lowest proportion among big-5 leagues was recorded in the English Premier League: 10.0%. Since 2012, this percentage has steadily decreased to reach a record low in the current season. Conversely, in the Spanish Liga, club-trained footballers account for almost one quarter of squads: 24.1%. The multiple trophies won by Spanish clubs in European club competitions suggest that the ability to field top level players from the youth academy provides a competitive advantage over rivals.

The annual census carried out since 2009 by the CIES Football Observatory on the profile of players active in 31 top division leagues of UEFA member associations confirms the decrease in the presence of club-trained players, the increase in that of expatriates and the growing squad instability throughout Europe. The main findings are presented in the 19th edition of the Monthly Report.

The study notably shows that the presence of club-trained players continues to decrease: from 23.0% in 2009 to 19.2% in 2016. This is the lowest value ever measured. In parallel, the level of expatriates has reached a new record in 2016: 38.7% (+3.9% since 2009). For the first time since our survey has been carried out, the percentage of expatriates is over twice that of club-trained players.

The greater international mobility of players brings with it a growing instability in squads. The average number of players recruited during the year among those present on the 1st October has increased from 9.1 in 2009 (36.7% of squads) to 10.7 in 2016 (43.9%). This is also a new record. The average length of stay of players in their employer club has never been as low as in 2016: 2.2 years.

The sample is made up of footballers present on the 1st October having played in domestic league matches during the current season or having taken part in adult championships during each of the two preceding ones. Second and third goalkeepers are taken into account even though they do not meet these criteria.

Real Madrid squad members were on average recruited at the age of 22.5 years. This is the lowest figure at big-5 league level. Issue number 162 of the CIES Football Observatory Weekly Post presents the data for the 98 clubs from the five major European championships. German and English teams are over-represented in the top positions of the rankings.

As developed in the 18th edition of the CIES Football Observatory Monthly Report, the best clubs focus their recruitment on younger players than less competitive teams. In the top five positions of clubs whose transfer policy is the most centered on young footballers are four Champions League participating teams: Real Madrid, Leverkusen, Dortmund and Tottenham.

In the top ten positions are four German (Leipzig, Leverkusen, Dortmund, Mainz) and four English teams (Tottenham, Bournemouth, Liverpool, Manchester United). Conversely, no German club is among the ten big-5 league teams whose recruitment strategy focuses on the most seasoned players. Italian side Cagliari is at the bottom of the table.

Issue number 161 of the CIES Football Observatory Weekly Post compares big-5 league teams according to the number of players in their current squad signed after January 1st 2016. The best performing teams recruited fewer footballers than the less competitive ones. German champions Bayern Munich only signed two players.

Among the eleven least active clubs on the transfer market are seven teams competing in the UEFA Champions League: Bayern Munich, Real Madrid, Lyon, Leverkusen, Paris St-Germain, Tottenham and Atlético Madrid. Athletic Bilbao, Hertha Berlin, Manchester United and Real Sociedad also are in the top eleven positions of the rankings.

The 18th edition of the CIES Football Observatory Monthly Report presents an in-depth analysis of the recruitment policies followed by clubs from the five major European championships. The study notably highlights that the most competitive teams focus on the fee paying transfer of young players with high potential and hold on to those who perform best over the long term.
