Bayern Munich had their 20-match unbeaten run in all competitions ended at Hoffenheim yesterday morning (Singapore time) as Andrej Kramaric's victor sealed the hosts' shock 1-0 victory.
Hoffenheim, who had never previously beaten Bayern in the league, are third with 51 and still on course for a Champions League place while Borussia Dortmund remain their closest rivals, remaining fourth after easing past Hamburg SV 3-0.
Bayern suffered only their second defeat of the season in midweek as they lost 1-0 at Hoffenheim, who are having an excellent season in 3rd, though Bayern nonetheless have a comfy 10 point lead at the top of the Bundesliga.
Hoffenheim head coach Julian Nagelsmann has compared the feeling of beating Bayern Munich to being "like a drug".
In the midst of that stretch, Bayern and Dortmund played out the most violent match in Bundesliga history that highlighted the increasingly fiery rivalry.
However, Baumann and the Hoffenheim defense withstood the Bayern onslaught.

The reverse fixture saw Chelsea run out 3-1 winners, with the match ending in the late sending off of Fernandinho and Aguero. Pep Guardiola believes the match against Chelsea will show where they are, as he challenged City to get a win on Wednesday.
"That was a setback at just the right time", defender Mats Hummels said of their first ever loss to Hoffenheim.
"It's a pity, we mustn't allow that to happen".
Kramaric fired home in the 21st minute to seal a win which moved the hosts to within one point of second-placed RB Leipzig and extended their unbeaten run to seven games. However, in the first round match, played back in early November, the victor was not able to reveal the victor at the stadium "Allianz Arena", in addition, it was the Bavarians who had to recoup - 1: 1.
With time running out, Lewandowski forced Hoffenheim goalkeeper Oliver Baumann into a superb diving save as they hunted the equaliser.
Aubameyang then broke free, rounded Hamburg goalkeeper Rene Adler to net Dortmund's third in the 93rd minute.
Kramaric scored the only goal of the encounter, as Hoffenheim dominated proceedings for most of the first half and deserved to get a second goal.
