U21 players: Premier League at the bottom of the table

Footballers under 21 years of age played only 5.3% of English Premier League minutes this season. This is the lowest figure measured at big-5 league level. At the opposite end of the table is the French Ligue 1: 12.1%.

The clubs per league having the most relied on U21 players are Monaco (34.6%), Valencia (25.5%), Empoli (23.3%), Bayer Leverkusen (23.1%) and Liverpool (19.8%). Conversely, U21 footballers played less than 2% of minutes in 27 teams out of 98, including at Champions League finalists Barcelona and Juventus.
