Barcelona and Real Madrid match-ups are famed for their hot-tempered atmospheres and wars of words before, during and after games.
This season's Champions League finalists drew 1-1 in a Bundesliga tie last weekend and the pressure seemed to boil over at times during the feisty affair but the Bavarians' CEO is keen to see the German rivalry remain civilised.
"Both clubs - Borussia Dortmund and Bayern Munich - have to make sure that we do not start to make the big German rivalry like it is in Spain," the 57-year-old told Ruhr Nachrichten.
"We do well to approach our matches with a great seriousness and respect to the game's history, and not to add fuel to the fire."
The former West Germany international is optimistic ahead of the tie on May 25 but says Pep Guardiola, who takes over from Jupp Heynckes as head coach in mid-June, will not travel to the Wembley game to ensure the team stay focused on this season's endeavours.
"He [Guardiola] does not want to come to the final," he added. "Because he does not want his appearance to distract [Bayern] in any way.
"The team are full of confidence but we will also have a dash of humility in London. We know that this will be a very tough game."
Bayern continue their build-up to the European showpiece event with a Bundesliga clash with Augsburg on Saturday.
