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 reacted angrily to a journalist stating that he had won just three of his 15 previous meetings with the Bavarians' new coach, Pep Guardiola, telling his inquisitor, "Your statistics are wrong".
Mourinho later conceded that perhaps it was he who had erred in terms of the head-to-head record but Hoeness was still less than impressed by the way in which the former Inter and Madrid trainer had responded to 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 has the utmost faith in Guardiola to bring home the trophy, but he did admit that he fears that fortune might 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 20:45CET.
