The UEFA and UEFA Respect flags and any other flag determined by UEFA must be flown at the stadium at all matches in the competition. They will be provided to the clubs by their association. From the league phase onwards, the competition flag must also be flown. It will be provided by UEFA to the clubs concerned in due time.
As from the league phase, 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 UEFA Europa League anthem provided by UEFA must be played. National anthems may not be played.
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.
