The home team must provide the visiting team with match balls of excellent quality for its training session on the day before the match as well as for warming up before the match. These match balls must be the same as those used for the match.
The applicable official UEFA Europa League match ball determined by the UEFA administration must be used for all matches from the league phase onwards and for the official training sessions before these matches.
The use of two-sided substitution boards (preferably electronic) is compulsory.
For each match of the qualifying phase and play-offs, the home club must ensure that two substitution boards are available.
