Der Kaiser is hoping Saturday’s ill-tempered Bundesliga affair is not a preview of how the two teams will act at Wembley on May 25
BVB boss Jurgen Klopp and Bayern sporting director Matthias Sammer were involved in an ugly exchange on Saturday after Rafinha was sent off for an elbow on Dortmund's Jakub Blaszczykowski.
And Beckenbauer fears the two sides will miss the opportunity to show the world the quality of German football if they allow tempers to boil over at Wembley.
“We had to endure ugly scenes that we did not want to see. Especially not on May 25. Stop these hostilities, don’t embarrass us!” he wrote in Bild.
“Let rationality prevail. The whole world is looking at Wembley. Bayern and Dortmund are there as representatives of Germany, too.”
The Germany legend also spoke of his desire for the creative talents of both sides to express themselves.
“Great players like [Marco] Reus, [Robert] Lewandowski, [Mario] Gotze, [Mats] Hummels and [Thomas] Muller, [Franck] Ribery, [Arjen] Robben, [Bastian] Schweinsteiger. We want to see the magic!”
