Diego Maradona described Argentina's humiliation at the hands of Germany as the toughest day of his life.

Miroslav Klose scored twice as Germany went through to the World Cup semi-finals with a 4-0 victory at the Green Point Stadium. It left Lionel Messi, the world's best player, sobbing in the dressing room and Maradona hinting it could be the end of his colourful reign as Argentina coach.

"I may leave," was his initial reaction before tempering it with a more considered response. "We will see what happens," he continued. "I haven't thought about leaving. I have to check that with my family and the players and there are things I have to consider."
