I have posted some numbers regarding possible cost/benefit of "Having an academy" previously, which was about the possible revenue from academy players.
This post is about clubs actually utilizing their own players and to what extent.
In order to shed some light on that the percentage (%) of minutes played by club trained players were analysed for the season 2021/22 and domestic league matches played until 19/04/2022.
The definition of club trained players is a players who have been at their employer clubs for at least three years between the seasons during which they celebrated their 15th and 21st birthday.
Starting at league level, the numbers stretched from a record-low of 4.0% in the Greek Super League to a record-high of 26.0% in the Argentinean Liga Professional. On average, teams from the 40 leagues fielded club-trained players for 15.0% of domestic league minutes.
At the club level worldwide the Slovaks of MŠK Žilina (85.5%) needs to be mentioned as the top of clubs, followed by Envigado FC (COL) with 76,4%, CA Banfield (ARG) with 66,6%, Dynamo Kyiv (UKR) with 62,9%, CA Lanus (ARG) with 62,6% and Rosario Central (ARG) with 60,2 %. Among the 42 teams who did not use club-trained footballers are familiar names such as Brentford, Bayer Leverkusen, Bologna and Udinese.
As usual I am having a closer look on the Big-5 where Athletic Club sits at the top with 55,8% of minutes played deriving from their own players.
The figure below shows the top 30 clubs from the Big-5 leagues, with 5 from the top 10 deriving from Spain, followed by teams from League 1 (FRA) and Bundesliga (GER). Manchester United is the first Premier League club with 27,6% and Genoa CFC the first Italian site with 23,9% minutes played by club trained players.
