Bayern Munich collapsed from 2-0 up as Borussia Monchengladbach produced a stunning comeback to inflict a second defeat of the season on the Bundesliga leaders.
A first-half brace from Jonas Hofmann drew Gladbach level at the break after a Robert Lewandowski penalty and a Leon Goretzka piledriver had given Bayern an early lead.
And Florian Neuhaus scored what proved to be the winning goal shortly after half-time with a curling effort from the edge of the box. Bayern pushed hard for an equaliser, but Gladbach clung on for a famous victory that keeps them in touch with the upper reaches of the league.
Bayern took the lead thanks to a helping hand from VAR, and another from Florian Neuhaus, with the referee adjudging from the replay that Gladbach’s midfielder had sufficiently handled the ball on the edge of the box to merit a penalty, allowing Robert Lewandowski to tuck the ball away.
There was no doubt about the validity of Bayern’s second though, with Leon Goretzka thundering in a long-range strike on 26 minutes to seemingly set the visitors on the path to a convincing win.
The hosts had other ideas however, taking a risk and pressing higher up the pitch to great effect. Gladbach repeatedly won the ball back in dangerous areas and on two such occasions Jonas Hofmann was played clean through to tuck the ball past Neuer’s right hand into the bottom corner to level things up just before half-time.
And Gladbach completed their comeback shortly after the break when Bayern were again robbed of possession in their own half and the ball was worked to Neuhaus on the edge of the box to rattle a superb shot into the top corner.
The result makes it six wins in their last 12 meetings with the German Champions for Gladbach, comfortably the best Bundesliga head-to-head record against Bayern.
Defeat leaves Bayern just two points clear at the top of the table with closest challengers Leipzig given a chance to go top when they face fellow big-hitters Dortmund on Saturday evening. Monchengladbach remain seventh but have pulled to within a point of the Champions League qualification spots.
