Bayern Munich had their lead reduced to five points as they lost their unbeaten Bundesliga record on Saturday in shocking emphatic style, going down 3-1 away to Borussia Moenchengladbach.
It is only the second time Pep Guardiola’s Bayern have lost at all this season after they went down 2-0 at Arsenal in the Champions League in October.
Gladbach coach Andre Schubert praised his side’s “sensational performance” while Guardiola said Bayern must learn from their mistakes.
“We lost our control after they went 1-0 up and they started to couter-attack,” said the Spaniard.
“We have to be able to learn from this game that we should never allow that to happen.”
It was Bayern’s first Bundesliga defeat since losing 2-1 at Freiburg last May as second-half goals by Oscar Wendt, Lars Stindl and Fabian Johnson left the Bavarian giants reeling.
Franck Ribery scored Bayern’s late consolation goal on his return after nearly nine months out with injury.
“It’s a pity, but it’s our own fault,” admitted Ribery.
“We will concentrate on the next game and hope to win,” he added as Ingolstadt can expect a Bayern backlash in Munich next Saturday.
Gladbach took a deserved lead when Raffael gave a return pass to Wendt and the Swedish international fired past Bayern goalkeeper Manuel Neuer on 54 minutes.
The hosts doubled their lead when Stindl volleyed home on 66 minutes.
Bayern centre-back Jerome Boateng was caught out of position and Johnson sprinted away to launch a shot past Neuer on 68 minutes.
Bayern pulled a goal back nine minutes from time when Ribery marked his 300th game in the famous red shirt by scoring off the bench to celebrate his first appearance in 269 days following a persistent ankle injury.
This is the first time Bayern have conceded three goals since losing 3-0 at Barcelona in the first leg of last season’s Champions League semifinals.
And their defeat leaves French champions Paris Saint-Germain as the only remaining unbeaten club in any of Europe’s traditional big five leagues.
