Berlin - Mid-table Hamburg are waiting on the fitness of two of their key stars for Friday's visit of league leaders Bayern Munich when the Bundesliga resumes after a month-long break.
Top-scoring striker Pierre-Michel Lasogga, who has bagged six goals in 16 games, is struggling with a shoulder injury while captain and centre-back Johan Djourou has picked up a knee injury in training.

"We can't draw on unlimited resources," said Hamburg coach Bruno Labbadia, whose side is tenth in the table with Bayern eight points clear at the top.
"We need a dream day to beat Bayern and it will be a great challenge."
Hamburg last beat Bayern in September 2009 and have been defeated 5-0 and 8-0 on their previous league meetings.
Labbadia is definitely without Bosnia defender Emir Spahic, who has torn a muscle in his stomach.
Star-studded Bayern have lost in the league just once so far this season.
Coach Pep Guardiola will be able to rely on a near full-strength team as they start the second half of the season in pole position to become the first club to win a fourth straight German league title.
