(Reuters) - AZ Alkmaar said on Friday they had taken significant measures including multiple bans on fans plus enhanced stadium security after the trouble that followed their Europa Conference League semi-final, second leg at home to West Ham United last week.
The visitors won 1-0 on Thursday to claim a place in the June 7 final against Fiorentina with a 3-1 aggregate victory but the match was overshadowed by family and friends of the West Ham squad being set upon after the whistle while celebrating.
