Ajax, FC Groningen, Harry Styles
Ahead of 21 May 2026
Ajax were forced to move their European play-off semi-final against FC Groningen to Volendam’s smaller Kras Stadion because Harry Styles concerts are booked at the Johan Cruijff ArenA. Groningen then threatened to boycott the fixture.
Local authorities barred away fans after separate supporter violence, leaving Groningen angry over the loss of ticket access. The KNVB entered urgent talks with officials as Ajax faced a major logistical problem before the play-off.
