The best way to deal with this kind of contest is to start off neutral, and then decide on a team whose way of playing you like, and then you back them.
And the supporters can be a factor there as well - you wouldn't really want anything to happen to give some of those lads satisfaction. (That's what I had in mind with my last post.) Fortunately I think the fact it's happening in Japan and Korea might cut down that sort of thing.
Of course you can always turn your nose up at it all, but where's the fun in that? That's almost as sad as thinking it really matters.
