The former French champions will host the German giants in Group F, having lost both their games so far.
"We are playing one of the biggest sides in Europe so we will have to give it 120% and Bayern will have to have an off day if we want to get a positive result," he said.
"It is David against Goliath. The most important thing for us is to believe we can do it. The only star in our club is our team.
"Franck Ribery is a tremendous player, but he is not the only one Bayern have - it will be hard to defend against [Thomas] Muller, [Toni] Kroos and the others as well. We will have to try to prevent Ribery from getting the ball, but there will be no 'anti-Ribery' plan."
In the other game in Group F on Tuesday, BATE Borisov will entertain Valencia in Minsk.
