While partnered with Donovan, Klose struck twice to lead Bayern to a 3-1 victory.
Bayern president Franz Beckenbauer said, "Toni is a typical Italian stirker, who needs a lot of room. That doesn't suit Miro Klose."
Last season, his first with Bayern, Toni scored 39 goals in 46 matches in all competitions. This season he leads Bayern with Bundesliga 9 goals, followed by Klose's 8, but Toni played poorly in his last two games.
Bayern general manager Uli Hoeness said that Bayern wasted "100,000" chances against Dortmund while the German press is deducing that Klose and Toni have become incompatible.
What that means for Donovan remains to be seen.
