Bundesliga leaders Bayern Munich suffered a shock 2-1 loss at Augsburg who struck twice against the run of play in the first half to snatch a memorable victory in Friday's Bavarian derby.
Goals from Mads Pedersen and Andre Hahn in the 23rd and 36th minutes put the hosts in the driving seat, before Robert Lewandowski pulled a goal back in the 38th, as Augsburg earned their third win in 21 Bundesliga matches against Bayern.
"It was not an undeserved win for Augsburg," Bayern coach Julian Nagelsmann said. "I am disappointed and for the first time as Bayern coach really frustrated.
"We did not use the large spaces we had in the first half. We made mistakes with possession. We had a numerical advantage in midfield but did not use it. We did not go over the wings when we also could."
"Then we were 2-0 back. At the end what we did was not enough to get a point."
With Thomas Muller playing his 600th game for the Munich club in all competitions, but Joshua Kimmich out again for a week in COVID-19 quarantine after contact with an infected person, Bayern had more than 75% possession at the start.
But Augsburg caught the visitors with a sucker punch when Pedersen powered home a low shot for his maiden Bundesliga goal.
With Bayern, who travel to Dynamo Kyiv in the Champions League next week, struggling to create chances, Augsburg struck again. Bayern lost possession in their own half and Hahn rose higher than the defence to head in a perfect Iago cross.
The celebrations of the home fans were dampened two minutes later when Bundesliga top scorer Lewandowski scored his 14th league goal from a Mueller assist to cut the deficit.
Augsburg remained disciplined in defence after the break and looked comfortable as they soaked up the Bayern pressure.
The visitors did not have many chances despite dominating possession but came close when Alphonso Davies' low shot in the 73rd flew just wide of the post before Augsburg goalkeeper Rafal Gikiewicz then denied Lewandowski from close range.
