Dinamo Zagreb and Hajduk Split fans hate each other. There is, however, a common figure who draws common ire from both camps.
This is Dinamo Zagreb executive director Zdravko Mamic. Loathed by fans, but loved by the media, Mamic is once again at the centre of controversy—an extremely unsurprising fact if you're aware of his story.
On November 22nd, 2014, under the alleged advice of Mamic, Dinamo unceremoniously blacklisted most of the Torcida—the hardcore faction of Hajduk Split supporters—from Zagreb's Stadion Maksimir for the first derby of the season.
In protest, Hajduk supporters, including the Torcida, boycotted the match, and the team followed suit, deciding to forfeit the game.
Six months later, ahead of their final meeting of the season, Hajduk supporters issued a statement declaring that they would again boycott their upcoming match at Zagreb—and the Bad Blue Boys, the ardent supporters of Dinamo, did the same. It was a union between supporters, across battle lines, against Mamic, who is seen as an enemy of all fans as much of a champion of his own club.
The teams, however, dutifully played on.
