The Dutch coach is brimming with confidence ahead of Saturday's encounter, and has stressed they have to focus on themselves rather than on their opponents
The Dutchman is high on confidence following the Gelsenkirchen side's good start to the 2012-13 campaign, and feels they have no reasons to fear Bayern.
"Confidence alone isn't enough to beat Bayern. Our results in the first few games have been good but we still have some inconsistencies in our play," Stevens was quoted as saying on the official Schalke website.
"Bayern are playing a different kind of football compared to last season. They press much more and switch the play faster.
"But we have to focus on our own qualities rather than worrying about our opponents. We have to play with courage and belief. We've no reason to be afraid of Bayern. Fear is a bad counsellor."
Saturday's encounter is scheduled to kick off at 13:30 UTC.
