"Dear Bayern Munich: The visit of the German Cup will be possible at any time after just a telephone notification,"

The sponsor confirmed that the poster is made to boost Dortmund and no offense for the Bavarian side.

Thomas Doll's side isn't tipped for success against Bayern on Saturday following their 5-0 humiliating defeat against the Bavarians on Saturday.

Dortmund are dreaming of a third Cup title after previous victories in 1965 and 1989.
