Bayern Munich's 2-2 draw with Eintracht Frankfurt on Saturday was "not worthy" of the club, according to Karl-Heinz Rummenigge.
The Bundesliga champions twice led through Arjen Robben and Joshua Kimmich, but they were pegged back and Marco Fabian secured a share of the spoils 12 minutes from time for hosts, who had been reduced to 10 men after first goalscorer Szabolcs Huszti was shown a second yellow card.
Bayern were also held by Koln before the international break and their latest slip-up saw them fail to take advantage of Friday's 1-1 draw between fellow high-flyers Hertha Berlin and Borussia Dortmund.
With Bayern yet to click into top gear under Carlo Ancelotti, CEO Rummenigge agreed with captain Philipp Lahm that Saturday's draw was a result of poor mentality.
"That was not worthy of FC Bayern," Rummenigge said. "We do not experience something like that so often.
"Today we must be satisfied with a point, like we started the game with.
"But we must go with another attitude to the pitch."
Bayern now have three successive home games to get back on track, starting with Wednesday's Champions League visit of PSV.
