The Borussua Dortmund coach says the reigning UEFA Champions League winners are "unstoppable."
The 46-year-old coach led Die Schwarzgelben to a 4-3 aggregate win over Los Blancos in the semifinals of last season's Champions League, only to lose 2-1 to their Bavarian rivals in the final at Wembley.
With Bayern having seemingly gone up another level since Pep Guardiola replaced Jupp Heynckes at the helm during the summer, Klopp now feels that Bayern is simply unbeatable.
"Real Madrid would have no chance of competing with Bayern," he is quoted as saying by A Bola. "Bayern are currently unstoppable. If the likes of Real Madrid and Manchester United have no chance against them, how can Dortmund beat them?"
Klopp, whose Dortmund side is currently 12 points behind Bayern in the Bundesliga having played one game more, added that while Barcelona is capable of beating the Bavarians in a one-off game, even the Catalans would be unable to eliminate them over two legs.
