On Saturday, 27 April 1991, only three days after making the European Cup final by advancing against favoured Bayern Munich via managing a hard-fought home draw in the famous emotional rollercoaster semifinal return leg in front of 90,000 fans, league leaders Red Star hosted their heated cross-town rival FK Partizan in the 88th league edition of the Eternal derby.
The match play resumed before being interrupted several more times throughout the second half due to Partizan ultras continuing to riot despite increased police presence around the south stand and even, at one point, pleas of the team's striker Predrag Mijatović sent by the head coach Miloš Milutinović in an attempt of calming them.
[1][2] Prompted by Prosinečki's claims, Ljupko Petrović, Red Star's head coach in 1991, expanded: "We didn't lose that match by arranging with someone from Dinamo beforehand to let them win.
I remember Franjo Tuđman being at the match and watching it from the luxury box with his cronies and the overall atmosphere within the stadium being extremely hostile such that no result but Dinamo's win was going to be acceptable.
At halftime I protested vehemently with the referee, a Montenegrin guy whose name I can't recall at the moment, and from what he told me it was apparent between the lines that it had already been decided we had to lose that match for political reasons.
Because Tuđman is sitting in the stands and because he doesn't want a Serbian team winning in the middle of Zagreb right in front of his eyes at a time when he's creating an independent state.
