The Swiss research agency uses the term 'home-grown players' for players who were signed to that club for at least three years between the ages of 15 and 21. The annual report shows that Ajax once again scored highest, as they did last year when there were 85 players from the Ajax youth academy playing in Europe's top competitions.
In second place is Dinamo Kiev: 80 players who play football in Europe were trained in Ukraine. Portuguese Benfica completes the top three with 76 players.
Ajax is also top of the league when it comes to the 'training index'. This also looks at education standards at the club where the player was trained, as well as the level at which the player is currently active.
