Lieberknecht said that while he has plenty of respect for the achievements of the champions, he does not want to give them too much so that his side is still competitive against them.
"Of course there is a great excitement that we will measure ourselves with currently the best club team in the world," the Bayern official website quotes him as saying.
"It's a mix of both [excitement and respect]. Of course there is a great anticipation, but both emotions balance each other out."
Braunschweig currently sit bottom of the Bundesliga, while Bayern are leading.
