A great list but I would have included APOEL V. Omonia (Cyprus). This has everything - the nationalist, ant-Turkish support of APOEL v. the left-leaning, internationalist Che Guevara loving Omonia support (I am with Omonia on this by the way). I think they were once part of the same club but split following the post WWII uprising against British rule. I believe some of the APOEL players who joined the revolt were subsequently hanged by the British. There clashes are supposed to be something else.
