On this day in 2011, AEK fans clashed with riot police at the Athens Olympic Stadium following their Greek Cup final victory over Atromitos.
AEK beat Atromitos 3-0 to win their fourteenth Greek Cup and end a nine-year trophy drought.
At the final whistle hundreds of AEK fans flooded on to the pitch in jubilation, with some running towards the Atromitos end.
The pitch soon became a battlefield as riot cops stepped in to prevent rival fans clashing and clear the pitch of the fans. The trophy presentation was delayed for 40 minutes as a result.
The kick-off was also delayed for several minutes as fans from both sides invaded the running track around the pitch and tried to get at each other, but were kept apart.
