The UEFA, FIFA, UEFA competition and UEFA Respect flags, the country flags of the two participating teams, and any other flag determined by UEFA must be flown horizontally at the stadium at all matches in the competition.
The countdown to kick-off must comply with the principles set by UEFA. For each match, the specific countdown must be communicated by the host association at the match organisational meeting.
The walk-on music provided by UEFA must be played from when the players emerge from the tunnel until they have lined up, at which point the national anthems of both teams must be played (instrumental versions of no more than 90 seconds each). UEFA's pre-match protocol defines which flags and other items are carried onto the pitch and how these are displayed as part of the line-up ceremony.
At all matches in the competition, the players are invited to shake hands with their opponents and the referee team after the line-up ceremony as well as after the final whistle, as a gesture of fair play.
