Top 10 club rivalries
10. Olympiakos v Panathinaikos
The "derby of the eternal enemies" has a brilliant ring to it and immediately lets you know that Greece's two biggest clubs don't get along. Like all the best derbies, this rivalry goes beyond the bounds of the football pitch, with Panathinaikos originally representing the upper class and Olympiakos originally representing the working class. Athens can come to standstill when the two clubs clash and often for days afterwards. The intense battles spill out on to the streets in the form of fighting, riots, and tragically, deaths on some occasions. Olympiakos have the wood over Panathinaikos, having taken out the Greek League 40 times, which is twice as many times as their arch enemies.
