Bayern sweat on Klose and Kahn for Lisbon trip

Bayern Munich's striker Miroslav Klose controls the ball during the German first division Bundesliga soccer match Bayer 04 Leverkusen vs. FC Bayern Munich at the BayArena in the western German city of Leverkusen 29 September 2007. Klose and goalkeeper Oliver Kahn are Bavaria Munich's main injury doubts for their UEFA Cup first-round second-leg tie at Belenenses in Lisbon on Thursday.

Striker Miroslav Klose and goalkeeper Oliver Kahn are Bavaria Munich's main injury doubts for their UEFA Cup first-round second-leg tie at Belenenses in Lisbon on Thursday.

Klose, the top scorer at last year's World Cup, has already scored eight Bundesliga goals this season and played a key role in Saturday's 1-0 league win over Bayer Leverkusen, but is struggling with a knee injury.

And Bayern captain Kahn, who is set to retire from the Bundesliga at the end of the season, missed Saturday's win with a painful elbow injury and is expected to miss the trip to Portugal with Bayern holding a 1-0 first-leg lead.

"Miro still has a few problems," said Bayern coach Ottmar Hitzfeld on Sunday. "It is doubtful he will play on Thursday.

"He still has a lot of pain and sometimes he can't even jog."

Klose's injury will give either Jan Schlaudraff or Lukas Podolski a rare chance to break into the first-team, while 23-year-old Michael Rensing will continue to deputise for Kahn.

"Oliver has had a sore elbow for months and it is being treated," said Hitzfeld. "I hope he can play."
