To me, the germans never were in the position where one could say that they deserved to be world cup winner. They have got pretty far, so far so good, but look at their opponents; they undoubtetly had the easiest way to the half-finals, and beating teams like costa-rica (and even getting scored 2 (!) goals from them), poland, sweden is not an art really. Argentina was the first real tough opponent and they didn't really show great skills there. ARG had a bad day, no luck and the germans won by penalties.
Germans can't loose, and they can't accept that they have been beaten by a great italian team. I mean, just look at the game; Germans did not have one really big opportunity. some far-range shots but thats it. Italian defense did really good (imo best in the world) and the 2 goals were more than deserved.
