Serbian fans are arguing on Olympiacos Facebook page: War of Partizan and Red Star fans over Partizan's draw! (PHOTO)

There is no doubt that the game between Partizan and Olympiacos will be a high-risk match because those are the clubs whose fans have a long history of conflicts and there are great tensions between the clubs.

Partizan's Grobari (Partizan fans) are in friendly relations with PAOK supporters, while Olympiacos fans are in fraternal relations with Delije (Red Star supporters), and there is no doubt that four fan groups will be included in the entire atmosphere during the next two matches.

The arguments on social networks, which started immediately after the results of the draw were presented, show that the tensions will be very high.

What is most incredible, is the fact that Serbs are fighting over the official Facebook page of Olympiacos. Partizan fans are writing insulting slogans against Olympiacos, and Red Star supporters are responding to them.
