I don't see any true germans saying anything about winning it all or even making it to the final yet, german fans are extremely happy with how our young team has played, but i don't see any sort of cockiness, unlike so many of my dutch friends who are already telling me about winning their first world cup and how they will win regardless of who they face in the final.
Germany worked Argentina today front to back, frustrated them with good defense and dominated offensively. Argentina did not fall apart, their defense was just never strong so they never had a great chance unless they scored lots of goals, which germany's defense made sure didn't happen.
Holland and Germany have both played very well and if they meet in the final i think it will be very well deserved and a great match. Germany seems to have a bit more offensive power, speed, and flare while Holland has a rock solid defensive core for the most part.
