Dutch winger Arjen Robben and Germany star Mario Gomez are expected to be in action for Bayern Munich this weekend as the club on Wednesday ruled out a new signing as cover for the injured Ivica Olic. Gomez injured his thigh after scoring the winner in Tuesday's 1-0 Champions League win at FC Zurich as Bayern wrapped up a 3-0 aggregate win over two legs to book their place in the main draw. "The (club's) doctor says there is no problem for Saturday," said Gomez on the Bayern website, ahead of the game at Kaiserslautern. The Germany forward's health is of particular concern to Bayern after Croatia striker Olic picked up a hip injury last weekend and was ruled out for up to eight weeks. Munich now have just two fit strikers in their squad in Gomez and Nils Petersen. Bayern released a statement on Wednesday to say they will not bring in a new striker as cover, with the transfer window set to close at midnight on August 31. "I have complete confidence in our existing squad," said coach Jupp Heynckes. "In addition, our medical department is confident that Ivica Olic will return to the squad in the near future. "All of us, the board, sporting director and coach, are confident that with our current team we can reach our goals for this season." Robben was on the bench in Zurich after struggling with a back injury. Bayern doctor Hans-Wilhelm Mueller-Wohlfahrt says the Netherlands star should be able to face Kaiserslautern, but there is no news about when the fragile Dutchman will be completely pain-free. "Arjen can play again on Saturday from the beginning, but the period for his full recovery is not currently defined," said Mueller-Wohlfahrt.
