On Saturday, 18 May 1991, Dinamo Zagreb hosted champions-elect Red Star Belgrade at Maksimir Stadium. The match was of no competitive importance since Red Star had already clinched the league title as it prepared to go to Bari some ten days later for the European Cup Final while Dinamo cemented its hold on the second place that ensured a UEFA Cup spot. However, the match still carried a degree of tension due to pitting a marquee Croatian side versus a marquee Serbian at a time when ethnic conflictss, some of them deadly, had started taking place in the Socialist Republic of Croatia, and especially in light of the fact this was the first time the two teams met at Maksimir following the previous season's Dinamo–Red Star riot in the stands, with that match being called off.
