The BVB coach says that the absence of his first-choice back line has put him under huge stress while playing down Bayern Munich's own fitness problems ahead of their showdown
The German giants saw Mats Hummels and Marcel Schmelzer pick up injuries on international duty to leave them without any of their first-choice defenders and Klopp feels that not even the absence of Franck Ribery for their opponents with a rib problem compares.
"I've picked up 80 per cent of my grey hairs this week," the 46-year-old joked at a press conference.
"The situation is not great, especially when one is in such a phase with eight games left until Christmas, but we already had a little time to get used to the idea.
"You have to say that every single team in this world would miss a Franck Ribery, no doubt about that. On the other hand, the replacement might be Mario Gotze, plus [Thomas] Muller and [Arjen] Robben on his side. Then they have [Mario] Mandzukic, Toni Kroos and so on and so forth. The problems Bayern have are bearable.
"Franck Ribery is an outstanding player who is going to be replaced by another outstanding player."
Klopp was reluctant to discuss his plans for restructuring his line-up to compensate for the absences, instead imploring his team to give their all on the pitch in order to challenge Bayern on Saturday.
"I have complex considerations but I do not intend for you [the media] to communicate the ideas [to Bayern]," he remarked.
"We will have to play an exceptional game to put our opponents out of the way before problems arise."
