Before each match, each team must indicate on the match sheet the numbers, surnames, first names, dates of birth and, if applicable, shirt names of the 12 (final tournament: 14) players in the squad, together with the surnames, first names and functions of the officials seated on the substitutes’ bench. The goalkeepers and team captain must be identified. Players must wear the shirt and short numbers as indicated on the match sheet.
Each team must have its match sheet validated by its competent association official and submit it at least 60 minutes before kick-off.
The maximum number of substitutes permitted per team is seven (final tournament: nine). The number of substitutions permitted during a match is unlimited. No substitutions are allowed during time-outs.
After the validated match sheets have been submitted no changes are allowed. Before the match has kicked off, the following exceptions are possible:
If any of the players indicated on the match sheet as forming the starting five cannot start the match due to physical incapacity, they may be replaced by one of the substitutes listed on the match sheet. The replaced player is taken off the match sheet and the quota of substitute players is reduced accordingly for the match in question.
If any of the substitutes listed on the match sheet cannot be fielded due to physical incapacity, they will be removed from the match sheet and the number of substitute players is reduced accordingly for the match in question.
If a goalkeeper listed on the match sheet cannot be fielded due to physical incapacity, he may be replaced by another goalkeeper from the list of 25 players.
The association concerned must, upon request, provide the UEFA administration with the necessary medical certificates.
