Germany manager Joachim Low described his team's performance as close to perfect following their demolition of Diego Maradona's Argentina.
Having brushed aside England in the last 16, Germany tore Argentina apart in Cape Town in the quarter-finals as a ruthless counter-attacking display earned a 4-0 win at Green Point Stadium.
Germany will now take on Paraguay or European champions Spain, who meet on Saturday evening, in the semi-finals and some pundits believe they could be classified as favourites for the tournament.
Low was delighted with the performance of his team as Thomas Muller scored in the first half before the second half saw Miroslav Klose score twice with an Arne Friedrich tap-in sandwiched in between.
The Germany manager said: "The team did everything nearly perfectly today.
"The result is nearly unbelievable because Argentina have a strong defensive team. It was first class that we were able to get so many goals."
Muller continued his impressive World Cup, but will miss the semi-final through suspension after collecting two yellow cards following a debatable handball.
Low said: "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."
Man of the match Bastian Schweinsteiger said regarding the victory over Argentina: "That gives you goose bumps seeing the way people are celebrating at home.
"We may have to play Spain next, they're the best team in the world in my view. But we're good enough, we believe in ourselves."
