Stadiums must be announced by the host associations via the designated UEFA online system at least 60 days before the match in question (and no more than seven days after the play-off draw).
When selecting a stadium, the host association must take into account the length of the journey to be undertaken by the visiting team. In principle, the stadium for a match must be within a 90-minute bus drive from the nearest international airport with daily flights from/to other European cities.
The host association must fix and enter the kick-off times online at least 30 days before the match in question (and no more than seven days after the play-off draw).
For reasons of sporting fairness, the last matches of a group must take place on the same day, and the UEFA administration is entitled to order these matches to be played at the same time.
