Winners of the Confederations Cup qualify for 2010? That's the first time I've heard that. Are you sure?
Growing up, the US national team, for all intents and purposes, didn't exist, so I've always been a Germany fan.
I support both, but when they meet (like they did in the 2002 quarterfinals), I am with the Vaterland. Can't help it, it's probably all the childhood indoctrination.
