Before each match, each team must indicate on the match sheet the numbers, full names, dates of birth and, if applicable, shirt names of the 23 players in its squad, together with the full names of the officials sitting on or next to the substitutes’ bench. The match sheet must be validated by the competent association official.
The 11 players indicated on the match sheet as forming the starting 11 must commence the match. The other players are designated as substitutes. The numbers on the players' shirts must correspond with the numbers indicated on the match sheet, on which the goalkeepers and team captain must also be identified.
Both teams must submit their validated match sheets at least 75 minutes before kick-off.
Only three of the substitutes listed on the match sheet may take part in the match. For the remaining matches of the qualifying group stage, as well as for the play-offs and the final tournament, up to a maximum of five of the substitutes listed on each team’s match sheet may take part in the match. Exceptionally, a sixth substitute listed on the match sheet may take part in the play-offs and final tournament exclusively during extra time. Each team may use a maximum of three stoppages in play to make substitutions (one additional stoppage in extra-time can be used). Substitutions made before the start of the match, during half-time, between the end of normal playing time and extra time, and at half-time during extra time do not reduce the number of stoppages in play that can be used. A player who has been substituted may take no further part in the match.
After the validated match sheets have been submitted by both teams, and if the match has not yet kicked off, no replacement is allowed, except in the following cases:
If any of the players indicated on the match sheet as forming the starting 11 cannot start the match due to physical incapacity, she 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. During the match, three (for the remaining matches of the qualifying group stage as well as for the play-offs and final tournament: five) players may still be substituted.
If any of the substitutes listed on the match sheet cannot be fielded due to physical incapacity, she may not be replaced, which means that the quota of substitute players is reduced accordingly for the match in question.
If none of the goalkeepers listed on the match sheet can be fielded due to physical incapacity, they may be replaced by registered goalkeepers not previously listed on the match sheet, subject to final approval by UEFA.
The association concerned must, upon request, provide the UEFA administration with the necessary medical certificates.
