I certainly thought Argentina was going to be a real opponent for Germany and was honestly concerned, but the Argentinians only played like Argentina for the first 20 minutes of the second half. Otherwise, even the first half (Germany led 1-0 at halftime) was a rout.
Overall, the referees seemed to be focused on not determining the outcome of the game themselves, which is laudable, and they did an excellent job overall, but it is worth pointing out that the yellow card that Thomas Müller got for a handball would not have been given had the referees seen that the ball bounced off of Messi's arm and onto Müller's -- so Messi should have got the card.
A truly unfair game, this soccer.
But it was the most enjoyable match in this year's World Cup from where I am sitting. Klose, known for his post-goal flips, has come under criticism in recent years for not being more effective and reacted by not flipping any longer. It was therefore good to see him let one fly on Saturday (see pics).
The German team has been quite modest overall, and modesty becomes Germany very well (because they basically kick everyone's ass), but because of the fight between the Argentinian and the German team in 2006, some of the German players warned Argentina before the game to be prepared for the worst. The German press at least partly responded by telling the German team to go back to being modest before they get their butts kicked. The comments below this article before and after the game are quite entertaining if you read German.
Did I mention that Germany is going to win the World Cup this year? If they keep playing like themselves (and do not turn into a completely different team like the French and Italians did -- or like the Argentinians did for 70 minutes on Saturday), they will be unstoppable. But don't hold your breath. Germany has played like Germany for five games running.
