Like I said you get more passionate games which are in part bigger due to coming from larger cities and countries, which actually doesn't mean a lot, it is just form of out pouring of self importance but as great rivalries go Celtic V Rangers is it, it has everything it encompasses the whole spectrum -political, religion, national identity. El classico has more going for it than the Buenos Aires Derby match, and it's not just about their global brand image, what it means to the average person in their traditional heartlands is more than that, but I still give the Old Firm the edge.
