Hey, I am cheering for the US team as well. But I don't see how that disproves my point. I think he is good to motivate a team for a short term goal like the world cup, but longterm development is another thing. He sparked a new enthusiasm in the german team 2006, but everybody was aware, that the tactical part was Jogi Löw and Hansi Flick. His Munich stint wasn't that great.
I do think the US team might upset Portugal, but I think Germany is out of their league.
But I am biased on that one.
