You mean besides laundering tens of millions of euros through his ties with the city holding mafia? Besides stealing tens of millions of euros via shady dealings with player transfers of which the club hasn't seen barely 5%?
He was quite literally investigated for this, and if they had anything on him he'd be in jail already.
Besides being at the head of the club during it's worst result crisis in european football in more than 50 years?
Are you trying to imply Dinamo was much better before him? Because they weren't. The only reason why that 90's squad was good is because they had a lot of veteran Croatian players with plenty of experience in top leagues around Europe.
Besides being tied to match fixing in the HNL for the past 10 years?
Only Hajduk fans are trying to accuse him of some imaginary match fixing, and that's incredibly sad because their club is the one that was actually involved in various shady things 10 years ago, including match fixing.
Besides changing more than 25 coaches in the past 10 years before finally installing his brother? Besides putting a wildly incompetent and disliked marionette at the head of the football federation? Besides having his son as the agent of the whole dinamo team up until 2 years ago? Besides selling 17 and 18 year olds in their first season of professional football? Besides being blatantly involved with politics? Besides alienating 99% of the teams fanbase, reducing the home attendance to about 5% of the maximum of the stadium on average during the past 5 seasons? Besides having to literally give away thousands of tickest so people would actually come to these games? Let's not forget his historically unprofessional, rude and disgusting way of talking with the press?
This entire part is just boring, baseless top level strawman stuff that gets reiterated constantly by Hajduk fans and so called online BBB who have never even seen Maksimir in real life. There's no doubt that his using his son as an agent for a lot of players, but I'm asking you once again - what the fuck does that have to do with you, or any other fan? Players don't care, except for Eduardo who didn't mind signing that contract when Mamic promised him transfer to top aclub (not to mention that he also sued his wife's uncle for whatever reason). And the fact that you actually think any of this has anything to do with BBB's boycott shows how incredibly clueless you are, I mean BBB even posted reasons why they hate Mamic on their website but I shouldn't even bother telling you that because it's obviously much simpler to make up various conspiracy theories about some secret cult ran by Mamic that's doing everything in their power to destroy Croatian football!! Even though our leagues coefficient is at all time high. It's also hilarious that Rijeka's fans, the only other club in Croatia that's even worth mentioning, never come up with such bullshit, it's only butthurt Hajduk fans that can't cope with the fact that their club is shit, and "online BBB" of whom vast majority has never even seen Maksimir in real life.
Reality is that Zagreb's crowd was always shit, except for big matches. One of Dinamo's lowest attendances ever was 10-11 years ago, when only around 400 people showed up because Dinamo was doing shit in the league (I think it was the season when Inter led by Modric finished above us). BBB are the only people suffering in this situation, and everyone else is just a hypocritical cunt. You all wanted BBB gone from the stands because you felt "unsafe" on Maksimir, and now everyone's suddendly joining them in solidarity.
