Anybody can list a billion rivals/derbys. If we are talking biggest/most important I think if we came up with a top 5 it would include (to me), in no particular order:
Those are clearly the four biggest to me ...
Boca Juniors - River Plate
Roma - Lazio
Barcelona - Real Madrid
Celtic - Rangers
The fifth spot I keep waffling on, but I would choose it from among:
Liverpool - Man United
Dortmund - Schalke
Fenerbache - Galatassaray
You forgot the Cairo derby. Also Belgrade derby. And Liverpool v Man U is not in the same level as the other ones you mentioned. And I mean for bitterness no success.
Germany - Netherlands is up there in top 5 national rivalries as well. The English might try to say England - Germany, but it's really only the English who worry over that one, the Germans don't care near as much about it.
The Germans like to pretend it doesn't matter but two countries involved in the deadliest war in history there is gonna be a rivalry.
