Germany goalkeeper Jens Lehmann is anxiously waiting to discover how bad the ankle injury he suffered during the hosts' 4-2 victory against Costa Rica in Friday's World Cup curtain raiser is.

The Arsenal shot-stopper received running repairs during the first half before having the joint strapped up at the interval.

"I twisted my ankle and I am in pain," said the veteran. "I don't know how bad it is. We will see."

Should Lehmann be unable to play in Germany's next Group A fixture against Poland, coach Jurgen Klinsmann will be able to call on an experienced replacement in the form of Bayern Munich's Oliver Kahn.
