However, despite the gulf that exists between the two clubs, Muller has called upon his teammates to ensure that they do "a professional job" in the Allianz Arena.
"We've been through so much, and we know what it's all about. We're not floating round in seventh heaven. We remain very self-critical," he told the club's official website.
"We set out to win our matches, and if we can, we obviously try to win them the way we've been doing recently. It won't be easy. We have to go out there and do a professional job."
Braunschweig were relegated from the top flight last season.
