VIDEO: Besiktas fans having a party at the stadium during Olympiakos game

Turkish giants Besiktas have progressed to the quarterfinals of the UEFA Europa League following a 5-2 aggregate win over Greek powerhouse Olympiakos Piraeus and their fans decided to throw a party right on the stadium.

With a particularly interesting piece of music blasting from the speakers and especially interesting moustache, Besiktas fans quite enjoyed themselves.

Have a look:
