Now that you've mentioned it... Not that I'm a great fan of soccer, since I don't see the point in so many people running on a field for just one ball and without any special rules/moves/etc. But I must say, I've been cheering for Barcelona for quite a while now. Before that I was a fan of Juventus, but I think that was due to the fact that my brother being in love with them. It's kinda infective, you know?
But yeah, I'm all Barcelona colors now. (Plus, Barcelona Bombers ftw! >_>)
