Teams must submit online the agreed playing attire colours to be worn for each match. The home team has the first choice as to which of its official sets of playing attire registered online it wears for its home matches. The proposed colours will be validated on-site by the referee team.
In any case, if the referee notices on the spot that the colours of the two teams could lead to confusion, a final decision on the colours is taken in consultation with the UEFA match delegate and the UEFA administration.
Any outfield player replacing the goalkeeper and playing as a flying goalkeeper must wear the exact same goalkeeper’s shirt, but with the outfield player’s own number on the back.
