I don't think thing any team that has played so far has shown anything Germany couldnt deal with (well, maybe Arjen but that's another story). Ironically we might be playing the 2nd best team at the World Cup today already. That's why, while I expect Germany to win I wouldnt be too worried if the drew or lose.
It's shocking really how undisciplined most other teams were tactically. Some of the matches looked like the players were playing for the first time together. The team that gets tactics & spacing down the best will most likely win it all. And with the Bayern / Dortmund set-up I just fancy our chances to be that team.
