Each club is responsible for submitting a list of a maximum of 40 players for the entire season, duly signed, to its association for verification, validation, signature and forwarding to UEFA. This list must include the surname, first name, date of birth and nationality of all players to be fielded in the competition in question, as well as the surname and first name of the head coach and first assistant coach. In addition, the list must include the confirmation by the club’s doctor that all players have undergone the requested medical examination; the club’s doctor is solely responsible for ensuring that the requested players’ medical examination has been duly performed.
The list of 40 players has to be submitted by 12 September 2023 (24.00CET). No club may have more than 40 players on that list, at least four of whom must be goalkeepers.
After the first matchday, the list of 40 players may be amended at any time up until seven days before a match. Any new players must be registered in accordance with the requirements set out in Article 36 and Paragraph 36.02.
Exceptionally, up to five players born on or after 1 January 2004 may be included on the list of 40 players, provided the following criteria are fulfilled:
-
The player has been eligible to play for the club concerned without interruption for the two years immediately preceding 19 September 2023, or has been eligible to play for the club concerned for two of the three years immediately preceding 19 September 2023 and registered with a maximum of one other club from the same association for an uninterrupted period of up to one year for the other one.
-
The player is duly registered on the list of 40 players by 12 September 2023 in accordance with Paragraph 37.01 and Paragraph 37.02.
-
The player is not replaced on the list of 40 players, except in the event of long-term injury/illness or registration with another club. An injury or illness is considered long-term if it lasts at least 30 days as of the day the injury or illness occurred. The club must provide UEFA with the necessary medical evidence in one of UEFA's official languages.
-
If the player is removed from the list of 40 players due to long term injury/illness (see Paragraph 37.04(c)) and replaced by another player born on or after 1 January 2004, he cannot be re-registered on recovery.
Each club must submit a shortlist of 20 eligible players from its list of 40 players by midnight CET the day before each match. No club may have more than 20 players on its shortlist before a match. As a minimum, 14 places on that 20-player shortlist are reserved exclusively for players who have been eligible to play for the club concerned without interruption for the two years immediately preceding 19 September 2023, or have been eligible to play for the club concerned for two of the three years immediately preceding 19 September 2023 and registered with a maximum of one other club from the same association for an uninterrupted period of up to one year for the other one. In addition, only three of the maximum of five players born on or after 1 January 2004 that are registered on the list of 40 players in accordance with Paragraph 37.04 may be included on this shortlist of 20 players.
No outfield player may be replaced on the 20-player list. Goalkeepers may be replaced at any time upon submission of written medical evidence of illness or injury in one of UEFA’s official languages before the start of a match.
The clubs and their associations are responsible for ensuring that the aforementioned provisions concerning player eligibility and lists of players are observed.
