Germany's No.1 Rene Adler Out of WC 2010

German No. 1 goalkeeper Rene Adler admitted on Tuesday he can not attend the World Cup in South Africa as rib injury.

"This was most difficult decision of my life," said Adler, a 25 year-old goalkeeper from Bayer Leverkusen.

"The pain is so great that I would not have been able to perform at my best over the longer term both in training and during matches," he said.

But an examination by Germany team doctor Hans-Wilhelm Muller-Wohlfahrt showed his injury is worse than first thought and he needs an operation to repair the ribs.

Germany coach Joachim Loew was very sorroy about Adler, but he said, Adler has to do that.
