In contrast, Dortmund went down to Real Madrid 3-2 on aggregate despite winning the second leg of their Champions League quarter-final and are now hoping to preserve second spot in the Bundesliga with five games left.
Saturday's game in Munich follows an ongoing war of words throughout the season that has drawn in coaches and club bosses.
The latest instalment of their off-the-pitch rivalry came this week with Bayern president-in-waiting Karl Hopfner accusing Dortmund CEO Hans-Joachim Watzke of making up stories regarding a loan the Bavarian's gave Dortmund in 2004.
At the time the Ruhr valley club was on the brink of bankruptcy with Watzke saying Bayern had demanded eight percent interest on the two million euros ($2.76 million)they had loaned out.
"I repeat Bayern did not contribute to saving Borussia Dortmund," Watzke said, arguing then Bayern boss Uli Hoeness was no "Mother Theresa".
Watzke took over at Dortmund about a year after the loan was given and he has been credited with turning around the club's finances, dragging them out of the red and into a successful and profit-making outfit.
He said he would never have done what his predecessor did, especially not in the form of a loan from Bayern.
