Bayern Munich have extended their lead at the top of the Bundesliga thanks to a 1-0 win over Borussia Dortmund.
The Bundesliga's 102nd Klassiker had plenty of talking points as both sides battled in a match which was tipped as a title decider, and it was Joshua Kimmich who struck the decisive blow with an incredible goal at the end of the first half.
The hosts didn't waste any time in the must-win Klassiker and Erling Haaland even saw a shot cleared off the line after just 30 seconds, although Jérôme Boateng didn't have to work too hard to keep the ball out of the back of the net.
Boateng couldn't stop Raphaël Guerreiro from scoring with a close-range header, but thankfully for Bayern Munich, the offside flag came to the rescue.
Borussia Dortmund had seen a shot of their own cleared off the line, but as Bayern Munich started to grow into the game, Łukasz Piszczek was alert to keep out Serge Gnabry's shot which found a way past Roman Bürki.
The hosts were on top throughout the first half, but they ended up going into the break one goal down after Joshua Kimmich was able to send a fantastic chip over Bürki and into the far corner of the net in front of an empty Yellow Wall.
The breakthough eventually came just before half time, but rather than coming from Erling Haaland or Robert Lewandowski, Joshua Kimmich emerged as Bayern Munich's unlikely hero.
The Germany international was able to work half a yard of space on the edge of the penalty area, but instead of hitting the ball as hard as he could, Kimmich instinctively sent a chip just out of Bürki's reach and the ball nestled into the side netting.
It was the worst possible time for Borussia Dortmund to concede.
But after starting the match at full throttle, it was no surprise to see the Black and Yellows come out in the second half with a similar level of intensity, albeit once again without any real cutting edge in the final third.
Thorgan Hazard and Mo Dahoud were able to threaten an equaliser, but Manuel Neuer largely stayed untroubled - which, in part, was thanks to Alphonso Davies' pace - and would have breathed a big sigh of relief after seeing Haaland forced off the pitch through injury.
Haaland's injury, however, didn't come before one of the small moments of controversy from Der Klassiker. The Norway international saw a shot deflected wide off Boateng's arm, but the Video Assistant Referee didn't intervene.
It was the last real sighter Borussia Dortmund were able to create, with Bayern Munich holding out and even coming close to adding a second through Robert Lewandowski.
The woodwork came to Dortmund's rescue this time around, but Lucien Favre's side were forced to helplessly watch on as their Klassiker rivals ground out another win in Germany's marquee game.
