The host association must ensure that the pitch is in the best possible condition for play.
For natural pitches, the height of the grass may not, in principle, exceed 30mm and the entire playing surface must be cut to the same height. If deemed necessary by the referee or the UEFA match delegate, the host association may be requested to reduce the height of the grass for the match.
Any full or partial replacement of a pitch ahead of a match must be communicated to UEFA in advance.
The host association must announce the pitch-watering schedule at the organisational meeting. The pitch must be watered evenly and not only in certain areas. As a general rule, pitch watering must be finished 60 minutes before kick-off. Additional pitch watering may be carried out if so decided by the host association in the qualifying competition, and by UEFA in the final tournament, provided it takes place:
-
between 15 and 10 minutes before kick-off; and/or
-
during half-time (for a maximum of seven minutes, allowing substitute players to warm up on the field of play).
The referee is entitled to request changes to the pitch-watering schedule.
All goals must be set up securely and in accordance with the IFAB Laws of the Game and UEFA's instructions.
It is the responsibility of the host association to ensure that the area immediately adjacent to the pitch is safe for players and referees.
