I'll go along with what you say about Germany Wolfgang. It all seems to have come together in the past few weeks. They are much better to watch and they are playing like a team and to their strengths.
If Argentina play to their full potential on Saturday, they will win. No one is taking that for certain though. I also think the Germans are quite fair enough to support Jurgen Klinsmann if they give Argentina a good game. They are proud of the effort and morale of this side. The DFB will not find it easy to sack him.
On the whole, I think this tournament has been a lot better than the previous one. The French and the Argentines barely turned up last time. No one can say that now. The quarter finalists all look like possible winners, with the exception of the Ukraine. I think they will prove cannon fodder for Argentina in the unlikely event that they make it to the semi final.
Brazil still look like the best bet, because they can win comfortably without even playing well. I don't expect the French to do them any favours though, and given a little luck...
