Panathinaikos fans attempt to attack Olympiakos players

A group of supporters charged onto the pitch while the Greek league leaders were warming up at the Stadio Apostolos Nikolaidis

Sunday's Athens derby was delayed after several Panathinaikos fans invaded the field to try and attack the Olympiakos players.
The fixture - known as the derby of eternal enemies - has a long history of violent clashes between the two sets of supporters.
And as Olympiakos players warmed up ahead of the game at the Stadio Apostolos Nikolaidis, home fans invaded the playing area and tried to assault them.
Police eventually were able to restore order, though, and the match kicked off around 15 minutes later than originally scheduled.
However, Olympiakos midfielder Pajtim Kasami was struck on the shoulder by a flare just before the start of the second half, resulting in another delay as the Swiss received treatment.
In addition, Olympiakos coach Vítor Pereira had a lucky escape when he managed to get out of the way of a chair thrown in his direction by another Panathainaikos supporter.
Panathinaikos went on to win 2-1 to move within three points of their arch-rivals at the top of the Super League.
