Panathinaikos fans broke the gate at Leoforos stadium, when members of Olympiacos entered the ground before the Greek League clash.
They began throwing objects as soon as they saw Vitor Pereira and Antonis Nikopolidis and everything got worse when the Portuguese manager waved towards the crowd like telling them "throw at me". Olympiacos president Vangelis Marinakis, on the other hand, tried to enter the field and flares were thrown towards him.
The fans then forced open the door, invaded the pitch and the fight with the police began. Right now the situation has calmed down and Marinakis will probably sit in booth 8 and not on the bench...
