Altınordu Football Academy (ALFA) publishes new research 'Club-Trained Players in Europe'



Altınordu FK’s Football Academy (ALFA) recently published its latest research “The Status of Club-Trained Players in Europe”.

The extensive study reveals the prevalence of club-trained[1] players in European teams and the playing time they received in 2018/2019 and 2019/2020 seasons. ALFA has studied and compared 32 leagues and 528 teams all around Europe to find out which clubs are the best in talent development.

The study tries to find an answer to these two questions:

1-) How many club-trained players are in the professional squads of European teams?

2-) How much playing time these players have received?

The countries that were included in the research were:

France, Spain, England, Germany, Italy, Norway, Czech Republic, Denmark, Scotland, the Netherlands, Sweden, Austria, Poland, Serbia, Ukraine, Romania, Russia, Croatia, Belgium, Turkey, Portugal, Greece.

The most striking result of the study is that only 58 clubs (%11) among 528 clubs all around Europe had at least %25 their own players in their professional team squad. This means only a small minority of clubs in Europe dedicate a significant portion of their squad to their home-grown players.

Another crucial finding was that the average percentage of club-trained players in all 32 leagues was just %9! In general, only one club-trained player finds himself a chance in squad.

However, since the numbers change significantly among different leagues, the study classifies the leagues in Europe as such: Top 5 (Ligue 1, La Liga, EPL, 1. Bundesliga, Serie A), First Division Leagues (Rest of the Europe), Second Division Leagues (All European Second Division Leagues).

Club-Trained Players By Country

In terms of the percentage of club-trained players in professional team squads the situation by country looks as follows:


[1] Played at least 1 year in the Academy level before reaching 18 years old.




The country that has the highest percentage of club-trained players in first division level professional team squads is Switzerland (%19). Turkey, Greece, Portugal and Italy are at the bottom with only %3.

While France leads the game among the Top 5 in Europe with %11, Serie A is again at the bottom with %3. In the second divisions, the Netherlands is at the top with %25 percent, while Belgium is the last with %2.

Club-Trained Players By Teams

When it comes to the team comparison, however, the results are different:




Overall, Sigma Olomouc from Czechia has the highest number of club-trained players in its squad with %57, followed by Stabaek Football from Norway with %48 and AZ Alkmaar from the Netherlands with %43.

Among the Top 5, Real Sociedad has the lead with %37, close rivals Athletic Bilbao and Barcelona chasing the club with %35 and %34 respectively. In the second divisions the second teams of the major Dutch clubs dominate the top: Ajax II %69, PSV II %65, AZ Alkmaar II %61 and Utrecht II %61. Porto II was the only team from another country that passed %50 threshold with %55.

Here, Turkish teams like Altınordu FK, Eskişehirspor and Bursaspor also find themselves a place. Eskişehirspor has the lead among Turkish teams with %42, followed by Altınordu FK %29 and Bursaspor %25. Nevertheless, considering the financial struggles Eskişehirspor and Bursaspor faced in the recent years and the necessity to play with club-trained players, Altınordu FK is the only Turkish team that found itself a spot in this chart voluntarily.

However, when it comes to the time given to club-trained players on the pitch, the picture changes for all teams in Europe. Slovacko from Czechia and Bodo Glimt from Norway gave 1.598 and 1.578 minutes to their home-grown players in the pitch, setting the highest points at the moment. Slovacko also has the title of highest playing time per player in Europe with 319 minutes per home-grown players.

In the Top 5, Athletic Bilbao (1.329), Atletico Madrid (1.215) and Köln (1.169) had the first three spots. Considering the fact that Atletico Madrid and Köln had only four and five club-trained players in their squad respectively, they gave the highest playing time per player with 243 and 292.

In the second division Real Zaragoza (1.380), Utrecht II (1.165), Helmond Sport (1.138) lead the playing time give to home-grown players. But since these teams have higher number of club-trained players in their squad compared to First Division teams, playing times per player are not impressive.

A Downward Trend

These overall results signify a downward trend in club-trained players combined with Poli et al. (2018) study “A comparative analysis of club-trained players in Europe”. That study showed that between 2009 and 2017, the proportion of club-trained players in the squads of teams analyzed went down year by year from %23.2 to %18.4. ALFA’s research shows that the situation is getting even worse as the number hit record low in the recent years with %9.

Added to that, the latest CIES report on "Club-trained players’ employment across Europe" also finds similiar results. Despite having a larger target group (those having been for at least three seasons between the ages of 15 and 21 in their employer club), clubs included in ALFA research like Sigma Olomouc, FC Slovácko and Real Sociedad found themselves a place in CIES report as well.

Against this background, ALFA study finds that 58 clubs that have at least %25 percent club-trained players in their squads can be considered as successful talent-developer clubs. These clubs have on average at least 10 players in their squads and give at least 900 minutes to their club-trained players. Hence, ALFA concludes that teams that are successful in raising their own players have at least ten club-trained players in their professional team squad and give at least 900 minutes of playing time to each of them.

The extensive study contributes to the talent-development research in football with the most recent statistics on club-trained players in Europe. ALFA continues to produce game-changer research in football development!
