Bayern Munich president Uli Hoeness has hit out at allegedly "unqualified comments" made by Chelsea boss Jose Mourinho ahead of Friday's Super Cup showdown between the two sides.
During the pre-game press conference, the Portuguese coach reacted angrily to a journalist stating that he had won just three of his 15 previous meetings with the Bavarians' new coach, Pep Guardiola.
And Hoeness admits he was less than impressed by the way the former Inter and Real Madrid trainer handled the line of questioning.
"I do think that the match [against Chelsea] is about prestige," the World Cup winner is quoted as saying by Kicker.
"Especially since Mourinho has, again, made some unqualified comments ahead of the match. So, I think our coach will be fired up about this game."
Hoeness says has the utmost faith that Guardiola will bring home the trophy but admitted that he fears fortune may once again favour Chelsea, who edged out Bayern on penalties in a dramatic 2012 Champions League final.
"I'll keep my fingers crossed and hope he will win it," he admitted. "However, I'm not sure there won't be certain forces working against the Germans again."
Bayern's eagerly-awaited meeting with Chelsea in Prague is scheduled to kick off at 19:45BST.
