actually here in the balkan people just are going there not to watch the match they are going to fight thier versus belive me i live in macedonia which serbia is the north of Macedonia 300 Miles away from my city 600 KM so yeah i know this happens a lot so belive me u don`t wanna go to matches here... they are not peaceful NBA rules
dude you think thats bad? theyre used to it. the Partizan stadium (that first one, second one was Red Star Belgrade) holds 8000, on average they have 23,000 attend the games. all chanting and cheering for Partizan or Gorbari Jug (grave diggers).
also there was an epic fight between Dinamo Zagreb and Red Star Belgrade fans in 1991 that they legit tore the stadium apart, they were using the seats as weapsons breaking walls, the police had to retreat a shit load of times.
