Each club is responsible for submitting to UEFA an A list of players (List A) and a B list of players (List B), duly signed by the club and verified, validated and additionally signed by its association. These lists must include the surname, first name, date of birth, shirt number and name (if applicable), nationality and national registration date of all players to be fielded in the UEFA club competition in question, as well as the surname and first name of the head coach and first assistant coach. In addition, the lists must include confirmation from the team doctor that all players have undergone the requested medical examination; the team doctor is solely responsible for ensuring that the requested players’ medical examination has been duly performed.
Only players who are duly registered with UEFA by means of List A or B can validly serve pending suspensions.
The club bears the legal consequences for fielding a player who is not named on List A or B, or who is otherwise not eligible to play.
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. List A must specify the players who qualify as being "locally trained", as well as whether they are "club-trained" or "association-trained".
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 ages 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 the player's nationality and age, has been registered with the player's current club for a period, continuous or not, of three entire seasons (i.e. a period starting with the first official match of the relevant national championship and ending with the last official match of that relevant national championship) or of 36 months. In the context of this paragraph, the season immediately preceding a player’s 15th birthday may be counted if the player's birthday is after the last match of the relevant national championship but before or on 30 June (winter championships) or 31 December (summer championships), and the season immediately following the player's 21st birthday may be counted if the player's birthday is on or after 1 July (winter championships) or 1 January (summer championships) but before the first match of the relevant national championship.
An "association-trained player" is a player who, between the ages 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 the player's nationality and age, has been registered with a club or with other clubs affiliated to the same association as that of the player's current club for a period, continuous or not, of three entire seasons (i.e. a period starting with the first official match of the relevant national championship and ending with the last official match of that relevant national championship) or of 36 months. In the context of this paragraph, the season immediately preceding a player’s 15th birthday may be counted if the player's birthday is after the last match of the relevant national championship but before or on 30 June (winter championships) or 31 December (summer championships), and the season immediately following the player's 21st birthday may be counted if the player's birthday is on or after 1 July (winter championships) or 1 January (summer championships) but before the first match of the relevant national championship.
If a club has fewer than eight locally trained players on its List A, the maximum number of players that can be registered on this list is reduced accordingly.
List A must be submitted online by the following deadlines:
-
4 July 2024 (24:00 CET) for all matches in the first qualifying round;
-
18 July 2024 (24:00 CET) for all matches in the second qualifying round;
-
1 August 2024 (24:00 CET) for all matches in the third qualifying round;
-
15 August 2024 (24:00 CET) for all matches in the play-offs;
-
3 September 2024 (24:00 CET) for all matches from the first match in the league phase up to and including the final.
For the qualifying phase and the play-offs, a club may register a maximum of two new eligible players on List A after the above-mentioned deadlines, provided the quota of locally trained players is respected. This registration must be completed by 24:00 CET the day before the relevant first-leg match and the club’s association must confirm in writing that the new player is currently eligible to play at domestic level. If the registration of a new player causes the number of players on List A to exceed 25, the club must remove a player registered previously to reduce the number of players on the list to 25 again.
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 24.00 CET 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 2003 and has, since his 15th birthday, been eligible to play for the club concerned for any uninterrupted period of two years, or a total of three consecutive years with a maximum of one loan period to a club from the same association for a period not longer than one year. 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).
If a club cannot count on the services of at least two goalkeepers registered on List A because of long-term injury or illness, the club concerned may temporarily replace the goalkeeper concerned and register a new goalkeeper at any time during the season and complete the official registration of List A with a goalkeeper fit to be fielded. An injury or illness is considered long-term if it lasts at least 30 days as of the day the injury or illness occurred. If the goalkeeper recovers before the end of this 30-day period, the player must nonetheless remain off List A until the end of such period. The new goalkeeper does not have to be locally trained, even if the replaced goalkeeper was. The club must provide UEFA with the necessary medical evidence in one of UEFA's official languages. UEFA may require further medical examination of the goalkeeper by an expert appointed by UEFA at the club's expense. Once the injured or ill goalkeeper is fit to be fielded again, he can resume his position in place of his substitute. The return of the original goalkeeper must be announced to the UEFA administration 24 hours before the next match in which the original goalkeeper is due to play.
With regard to the definition of a “season” to be found in Paragraph 31.06 to Paragraph 31.07 of these regulations, as far as the determination of “locally trained players” is concerned, the relevant dates to be taken into account are those of the respective national championship calendar as originally scheduled, i.e. the prolongation of a national championship calendar due to an extraordinary situation, such as in the case of the 2019/20 season, is not taken into account. Furthermore, for the 2020/21 season, the period starting with the first official match of the relevant national championship and ending with the last official match of that relevant national championship is counted as a full season regardless of the actual start and end date due to the extraordinary situation.
