How do European squad lists work?

The Premier League transfer window has only just closed, but some teams immediately had another deadline to meet - registering their Champions League, Europa League or Conference League squads. Clubs had to submit their senior team players to Uefa by on Wednesday. But squads are actually split into two separate lists - and there are a number of criteria that have to be met.

Clubs must register a 'List A' and 'List B' squad. This is the list that had the Wednesday evening deadline. List A contains a maximum of 25 players, with a minimum of eight 'locally trained' squad members.

Of those eight, no more than four can be 'association-trained' instead of 'club-trained'. If the club doesn't submit eight locally-trained players, their maximum squad number of 25 is reduced proportionally. For example, should they only register six locally-trained players, their squad maximum becomes 23 players.

There must be at least two goalkeepers registered in List A - and at least three in total across Lists A and B. The only deadline for this list is that it must be submitted to Uefa no later than the day before a match. There is also no upper limit to the number of players who can be on List B.

This list caters for more junior members of a club's squad. A player is eligible to be on List B if they: have been eligible to play for the club for two consecutive years since their 15th birthday or have been eligible to play for the club for three consecutive years, including a loan spell within the same association, since their 15th birthday Players aged 16 can also be on List B if they have been registered with the club for the previous two years uninterrupted. Players who changed clubs after participating in any Uefa qualifying rounds or play-offs are permitted to play for their new side from the league phase onward.

After the September deadline, List A squads are locked in for the league phases of European competitions. However, should a club reach the knockout stages, they have until on 4 February 2027 to register a maximum of three new players. There is again no restrictions on players that have played for another club during any stage of any European competition up to that point - if they have changed clubs in the January transfer window, they can play for their new team from the knockout rounds onward.
