Bayern Munich star Muller: Beating Argentina just insane
The youngster, who continued his impressive World Cup but will miss the semi-final through suspension after collecting two yellow cards, was staggered by the performance and the 20-year-old could not hide his emotions.
Germany coach Joachim Low said: "It's insane to beat Argentina 4-0. It's hard to find the words for a result like that.
"I think Germany is quaking right now and that's the right way to celebrate this."
Low said of Muller's suspension following a debatable handball: "The fact that we won't have him is a serious blow because he has shown how dangerous he is.
"I saw his yellow and don't see why he got it. The ball touches his thigh then his arm from a short distance. I really question the yellow.
"But in the past we have been able to replace people like Muller and we will continue to do so as we move forward."
