UEFA’s Europa League squad regulations



No club may have more than 25 players on List A during the season. As a minimum, eight places are reserved exclusively for "locally trained players" and no club may have more than four "association-trained players" listed in these eight places on List A.

A "locally trained player" is either a "club-trained player" or an "association-trained player".

A "club-trained player" is a player who, between the age of 15 (or the start of the season during which he turns 15) and 21 (or the end of the season during which he turns 21), and irrespective of his nationality and age, has been registered with his current club for a period, continuous or not, of three entire seasons or of 36 months

An "association-trained player" is a player who, between the age of 15 (or the start of the season during which the player turns 15) and 21 (or the end of the season during which the player turns 21), and irrespective of his nationality and age, has been registered with a club or with other clubs affiliated to the same association as that of his current club for a period, continuous or not, of three entire seasons or of 36 months.

If a club has fewer than eight locally trained players in its squad, then the maximum number of players on List A is reduced accordingly.

Each club is entitled to register an unlimited number of players on List B during the season. The list must be submitted by no later than 24.00CET on the day before the match in question. A player may be registered on List B if he is born on or after 1 January 1997 and has been eligible to play for the club concerned for any uninterrupted period of two years since his 15th birthday by the time he is registered with UEFA. Players aged 16 may be registered on List B if they have been registered with the participating club for the previous two years without interruption.

Each club must include at least two goalkeepers on List A and at least three in total (List A and List B combined).
