For each round of the competition in which a club is participating, it is responsible for submitting a list of no more than 25 players, duly signed to its association for verification, validation, signature and forwarding to UEFA. Three of these players must be goalkeepers. This list must include the surname, first name, date of birth and nationality of all players, as well as the surname and first name of the head coach. The club must complete this list online by 24.00CET seven days prior to the start of a mini-tournament or the finals at the latest.
Only 14 of the players on the list of 25 will be eligible to play in each round of the competition. The shortlist of 14 players, two of whom must be goalkeepers, must be submitted online by 15.00CET the day before the first match of the team in each round of the qualifying stage and two days before the first match in the finals. A signed copy of this list must be handed to the UEFA match delegate at the mini-tournament organisational meeting and to the UEFA administration at the heads of delegation meeting for the finals. In addition, the lists must include 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.
For identification purposes, UEFA match delegates may make a visual check of each player participating in the competition. As a rule, one such visual check takes place at a mealtime at the team’s accommodation before the first match of a team in each stage of the competition.
A maximum of one outfield player named on the list of 14 may be replaced by another player from the list of 25, upon submission to the UEFA match delegate of written medical evidence of illness or injury in one of UEFA’s official languages no later than 09.00CET on the day of the relevant match of a mini-tournament or the finals. The replaced player can take no further part in the mini-tournament or the finals and no other outfield player may be replaced. In cases of particular hardship and upon reasoned request, the UEFA General Secretary may grant exceptions.
If a club cannot count on the services of at least two goalkeepers registered on the list of 14 players because of injury or illness, the club concerned may temporarily replace the goalkeeper(s) concerned on the list of 14 at any time during the competition, upon submission to the UEFA match delegate of written medical evidence of illness or injury in one of UEFA's official languages. The replacement goalkeeper(s) must be taken from the list of 25. Only if there is no eligible goalkeeper left on the list of 25 may another be registered. The club must provide UEFA with the necessary medical evidence. UEFA may require further medical examination of the goalkeeper(s) by an expert appointed by the UEFA administration at the cost of the club. Once an injured or ill goalkeeper is fit to be fielded again he can resume his position in place of his nominated substitute. Any such changes must be announced to the UEFA administration at least 24 hours before the next match in which the goalkeeper is due to play.
The clubs and their associations are responsible for ensuring that the aforementioned provisions concerning player eligibility and lists of players are observed.
