Germany coach Joachim Low admits out-of-sorts striker Miroslav Klose will find it tough to turn his form around in time for the World Cup.

The 31-year-old, who has scored 48 times in 95 games for his country looked a shadow of the player who finished top scorer at the 2006 World Cup in Saturday night's friendly win over Hungary in Budapest.

"It is clear that it will be no easy task to get Miro in form," Low said in the Bild newspaper. "It will be hard work, for him, for us. He has to work a lot."
