Coach Joachim Low believes Germany showed the 'will of champions' in Saturday's 4-0 World Cup quarter-final demolition of Argentina.
Germany followed up their 4-1 last 16 victory over England with a breathtaking display of attacking football against the much-fancied South Americans in Cape Town.
Thomas Muller's early strike was followed by two goals from Miroslav Klose and a late fourth from defender Arne Friedrich.
"We really turned in an incredible showing," said Low, whose side now face Spain in the semi-finals.
"Scoring four goals against Argentina you have to say that that was class.
"We really stepped on the gas in the second half and played a liberated style of attacking football.
"I have been proud of my team for a long time, not only today. We played some really great football in the second-half and the team has shown the will of champions.
"This result and the amount of goals we scored was almost unimaginable before the game."
