I don't care for either of the Old Firm for a whole host of reasons. The behaviour of of many (not all) Celtic and Rangers fans hasn't exactly been endearing when they visited us, particularly Rangers when they did so much damage when they came here. I don't like either. Come on Frankfurt.
Check the videos I've put on the Rangers thread. 98% of the fans are there for a good time and a bevvy in the sun. Nearly all good relations, apart from the brain dead that call themselves hooligans that look for trouble.
