Bayern were beaten 3-2 by Manchester City in the Champions League on Tuesday night and Van Marwijk does not think that one defeat will lead to another.
"I think they'll react in a professional manner," he told Bundesliga.com.
"They are one of the best teams - perhaps the best - in the world at the moment. They won't allow one defeat to knock them off their stride."
The game kicks off on Saturday at 2.30pm.
