Klinsmann also defended Chelsea new boy and national captain Michael Ballack after criticism of his World Cup performances.

Ballack was ruled out of the opening game against Costa Rica with a calf injury, and the same problem means he missed the third-place play-off with Portugal.

Klinsmann said: "Michael Ballack has a very important role. He has literally filled out his role of captain at the World Cup.

"He has great strength and we speak of him with the greatest respect."

"I think the Argentina game was the best possible example of the character of Michael Ballack.

"He was plagued by cramp and left the pitch, but he wouldn't be substituted and only left the field after the game was decided."
