Each participating team, via its national association, must provide the UEFA administration with a list of 30 players, including at least three goalkeepers as well as a head coach for each round in the competition. This list must be completed online at least 20 full days before the start of each mini-tournament and the final tournament. Once this list has been submitted no changes are allowed.
From the list of 30, a final list of 18 (final tournament: 20) players must be completed online by 15.00CET the day before the first match of the tournament. A signed copy together with each player’s passport/identity card must be handed to the UEFA match delegate at the organisational meeting organised the day before the start of each mini-tournament and the final tournament.
For identification purposes, a UEFA representative makes a visual check of each player participating in the competition. As a rule, one such visual check takes place at a mealtime at the teams’ accommodation before a team's first match in each mini-tournament and the final tournament.
The players named on the final list of 18 players (final tournament: 20) are entitled to play in the mini-tournament or final tournament. A maximum of one outfield player named on this list may be replaced 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 three hours before the start of the team’s first match in each mini-tournament or the final tournament. The new player must be selected from the corresponding list of 30 players. The replaced player can take no further part in the mini-tournament or final tournament and no other outfield player may be replaced during the mini-tournament or final tournament. However, goalkeepers may be replaced at any time during the mini-tournament or final tournament upon submission to the UEFA match delegate of written medical evidence of illness or injury in one of UEFA’s official languages. Any new goalkeeper must be selected from the corresponding list of 30 players. Replaced goalkeepers can take no further part in the mini-tournament or final tournament in which they are replaced. In cases of particular hardship and upon reasoned request, the UEFA General Secretary may grant exceptions.
The eight official 20-player lists for the final tournament are published by the UEFA administration.
The associations are responsible for ensuring that the aforementioned provisions concerning player eligibility and lists of players are observed.
