England vs. Argentina

What about your country? Which country do you see as your main rival?
And what about friendships, of if that is a too strong word, sympathies? I'll list a few for my country Germany:
Germany & Italy (although it looks like this will change in future after the events last year)
Germany & France (used to be major rivals, now it's a quite respectful relationship)
Germany & Scotland (Scots like us because the English hate us I guess)
Germany & Japan (always have been friends....)
