This year, you really shouldn't be talking about fan behaviour. But don't make me enter this game, because I hate pointing fingers at anyone but the idiots who create trouble. No team in Greece is innocent, you know that very well.
In the last 10 matches between the two teams there are 4 victories for Olympiakos, 2 draws and 4 for PAOK.
Listen, I'm not suggesting PAOK is better than Olympiakos this year or that we enter the game as favorites (in fact, I predict a defeat for PAOK), nor that history favors us. But to claim that any result is such a match is an upset shows basic ignorance of football dynamics.
