Bayern Munich had Dayot Upamecano sent off in a 3-2 defeat at Borussia Monchengladbach that dealt a fresh blow to their hopes of winning an 11th consecutive Bundesliga title.

The French defender received his marching orders in the eighth minute for a messy challenge, and goals from Lars Stindl, Jonas Hofmann and Marcus Thuram lifted Gladbach to a deserved win. Hofmann scored one and had two assists in a masterclass.

Daniel Farke's home side had won just one of their past five league games, but they did well here, reasserting themselves in the second half after Eric Maxim Choupo-Moting equalised Stindl's opener before the break. Mathys Tel's late strike for Bayern was scant consolation.

It leaves Bayern in danger of being knocked down to second place when Union Berlin face Schalke on Sunday, while Borussia Dortmund will have the chance to move level on points with Julian Nagelsmann's Bavarians when they host Hertha Berlin.

Bayern made a dreadful start, with Dayot Upamecano ordered off after bringing down Alassane Plea who got goal-side of the centre-back after a hopeful long ball.

The home side snatched a 13th-minute lead when a free-kick on the right was played by Hofmann to captain Stindl on the edge of the penalty area and his low strike found the bottom-right corner, beating Yann Sommer.

Bayern made a tactical change, replacing captain Thomas Muller with defender Joao Cancelo, but Stindl should have had a second goal for Gladbach in the 24th minute when he shot six inches wide after being picked out on the penalty spot by Kouadio Kone.

It was a major let-off and Bayern drew level in the 35th minute when Alphonso Davies dashed down the left and played a low centre that Choupo-Moting drove past Jonas Omlin for his eighth league goal of the season.

Yet it was Gladbach who struck next, in the 55th minute, when Plea's smart pass across goal from the right was calmly slotted in by Hofmann. It was also his eighth goal of the campaign, and Plea's eighth assist.

Ramy Bensebaini rattled the Bayern crossbar moments later, while at the other end Cancelo sent a drive from the edge of the box into the side-netting and Davies shot wildly wide.

Thuram looked to have sealed victory in the 84th minute, turning in a pass from Hofmann, before Tel turned in Bayern's second from close range in stoppage time amid a frantic finish.

What does it mean?

Bayern cannot buy a win when they ship the opening goal on league duty. They have now failed to win their last eight games when conceding first in the Bundesliga, and that is a problem for a champion team.

Great teams find a way, and on the evidence of much of this season, not just this setback, we are possibly not looking at a great Bayern.

Nagelsmann is winless in five games now against Gladbach in all competitions since joining Bayern (D2, L3).

French folly

It was a Frenchman who was the toast of Bayern in the 1-0 win at Paris Saint-Germain on Tuesday, when Kingsley Coman got the only goal.

Here it was another Frenchman in Upamecano whose clumsy defending proved costly. The red card was his third in the Bundesliga, and first since June 6, 2020, when he was an RB Leipzig player.

It was also the earliest a red card has been shown in the Bundesliga this season.

Gladbach pair at it again

Stindl and Hofmann rarely give Bayern a quiet moment. On this occasion, Stindl's goal was his eighth goal involvement against Bayern in the Bundesliga, while Hofmann's assist was his ninth such involvement against the champions.

Hofmann's 10th involvement came when he fired home to give the hosts a 2-1 lead, and his 11th brought about the hosts' third. Among current Bundesliga players, nobody has been involved in more goals against Bayern, with Marco Reus also on 11 involvements.

What's next?

Bayern will be back on home turf next weekend when they host Union Berlin on the Sunday. Gladbach do not have to wait so long for another Bundesliga game, with a trip to Mainz coming up on Friday.

Jonas Hofmann played a pivotal role as Borussia Monchengladbach incredibly came from two goals down to defeat Bundesliga champions Bayern Munich 3-2 on Friday.

Robert Lewandowski scored his 20th top-flight goal of the season from the penalty spot after an inexplicable handball from Florian Neuhaus, and Leon Goretzka had Bayern cruising at Borussia-Park in the 26th minute.

However, Hofmann struck twice in the space of 10 minutes to send the teams into half-time level and Neuhaus atoned for his earlier error with what proved to be the winner in the 49th minute.

Gladbach consequently became the first team since Cologne in February 2011 to defeat Bayern in the Bundesliga after falling 2-0 down.

Lewandowski put Bayern in front from the penalty spot following a bizarre handball by Neuhaus, though referee Harm Osmers only pointed to the spot after a VAR check.

Bayern doubled their advantage six minutes later, Goretzka intercepting Matthias Ginter's pass and drilling a venomous effort past Yann Sommer after a one-two with Leroy Sane.

Gladbach reduced the deficit when Rami Bensebaini regained the ball high up the pitch and a quick passing move ended with Hofmann sliding Lars Stindl's throughball past Manuel Neuer.

The hosts drew level in first-half stoppage time when Stindl dispossessed Joshua Kimmich and fed Hofmann for another cool finish - the VAR confirming he was onside when the pass was played.

Gladbach completed the turnaround four minutes after the restart, Hofmann intercepting Niklas Sule's pass and teeing up Neuhaus to curl a wonderful effort into the top-right corner.

Marco Rose's men sat deep and Ginter cleared a header from Sule off the line in the 91st minute, opening the door for RB Leipzig to replace Bayern at the Bundesliga summit if they can beat Borussia Dortmund in a mouthwatering clash on Saturday.

What does it mean? Worries at the back for Flick

Bayern's defensive struggles continued against Gladbach, with Neuer now on a 10-game run without a clean sheet in the Bundesliga for the first time in his career.

He was not helped by Benjamin Pavard giving away possession prior to Hofmann's first, while Sule played a role in allowing the other two Gladbach goals.

Securing the future of David Alaba, who will be out of contract at the end of the season, never seemed quite so important.

Having it Lars

Most teams would think the game is beyond them when falling 2-0 down to Bayern, but Gladbach captain Stindl led by example to turn the game around. He set up both of Hofmann's goals with a pair of quality passes and contested 11 duels before being substituted in the 82nd minute.

Sluggish Sule

Sule replaced Jerome Boateng in the centre of defence but endured a disappointing outing. He played Hofmann onside for the equaliser just before half-time and within minutes of the restart his stray pass resulted in Neuhaus putting Gladbach in front.

What's next?

Bayern are in DFB-Pokal action against 2. Bundesliga side Holstein Kiel on Wednesday, while Gladbach have a week to prepare for a Bundesliga clash with Stuttgart.
