BERLIN - Bayern Munich's injury crisis will not derail the team's challenge for European and domestic honours over the coming weeks, coach Jurgen Klinsmann said on Tuesday. Germany international Miroslav Klose could be out for eight weeks after undergoing ankle surgery while Italian striker Luca Toni has been missing for a fortnight with a heel injury. U.S. international Landon Donovan returned to the Los Angeles Galaxy days ago after a brief loan spell with the German champions, leaving Lukas Podolski, who had previously been confined to a bit-part role and will rejoin Cologne at the end of the season, as the sole striker. "In the past few weeks Podolski has been doing a great job," Klinsmann told German DSF television. "We have got a battle-worthy team. I am not pessimistic and I fully believe that we can tackle the challenges that are ahead." Bayern are through to the quarter-finals of the Champions League and are second in the Bundesliga, four points behind Hertha Berlin with 10 matches to go. Donovan had joined Bayern on a three-month loan in the hope of a longer-term deal, as the U.S. striker tried his luck in the Bundesliga for the third time in a decade. "It would do the team a lot of good if we still had him (Donovan) with us," Klinsmann said. "Now that Donovan is back in the United States and Toni is still having some problems with his heel, we are a bit thin."
