Well that was fun.

What a week it has been for Bayern Munich.

On Friday, Xabi Alonso, reportedly their top target to replace manager Thomas Tuchel at the end of the season, committed his future to Bayer Leverkusen and effectively ruled himself out of the running to take charge this summer.

Tonight, their hopes of winning a 12th successive title took a major hit at the hands of rivals Borussia Dortmund in Der Klassiker.

Goals from Karim Adeyemi and Julian Ryerson either side of half-time sealed the win for the visitors to strengthen their chances of securing a top four finish and Champions League football.

Arsenal fans might take some comfort from tonight's result too.

The Gunners face Bayern Munich and, of course, former Tottenham striker Harry Kane in the quarter-finals of the Champions League.

The first leg of that tie takes place at Emirates stadium on 9 April with the return fixture in Germany on 17 April.

The Borussia Dortmund players are making the most of this.

Bayern Munich have already retreated down the tunnel but the visitors have taken up a position down by the corner flag and they are dancing around in front of their own fans.

Mats Hummels is front and centre and deservedly so.

What a way to celebrate breaking the record for the most appearances in Der Klassiker.

The wins puts Borussia Dortmund back up to fourth, they had dropped to fifth earlier today after RB Leipzig drew with Mainz.

That's three victories in a row for Dortmund as they look to ensure they are playing Champions League football once again next season.

It's all over!

Borussia Dortmund claim their first Bundesliga win at Bayern Munich since April 2014.

Bayern Munich's hopes of winning a 12th successive league title are hanging by the thinnest of threads. They are 13 points behind leaders Bayer Leverkusen with seven games left to play.

Bayern Munich have a corner but Mats Hummels wins the first header and here come Dortmund on the break.

There's a misunderstanding between ball-carrier Emre Can and runner Marco Reus as it rolls through to goalkeeper Sven Ulreich.

Mats Hummels strides up to the halfway line and attempts an outside of the boot pass in the direction of Julian Ryerson on the right.

He's been pretty much spot on with most things tonight and it might have gone to his head.

It's straight out for a throw-in.

As that VAR check was taking place the board went up for five additional minutes.

We've already gone through two of those but there's likely to be more on top due to the stoppage.

The goal has been chalked off.

It's tight but Harry Kane is offside.

Bayern Munich fans are heading for the exits in large numbers. You can see huge swells of red seats around Allianz Arena. They've seen enough.

You can be sure the travelling Dortmund fans won't be going anywhere for a while.

It's almost exactly 10 years since they last won a Bundesliga game at Bayern.

Eric Maxim Choupo-Moting is also on as Bayern Munich's last change with Alphonso Davies off.

Jamie Bynoe-Gittens and Marius Wolf are brought on as the final two changes for Borussia Dortmund.

Jadon Sancho and Karim Adeyemi go off.

It might be worth mentioning at this point that Bundesliga leaders Bayer Leverkusen trailed Hoffenheim 1-0 until the 88th-minute earlier today.

Leverkusen went on to win that match 2-1.

There are just under 10 minutes left at Allianz Arena...

Julian Ryerson catches the heels of Mathys Tel as he controls the ball and it's a free-kick around 30 yards from goal.

Joshua Kimmich delivers the free-kick and it's inches over the head of Harry Kane.

Dortmund are showing great organisation here.

All the play is deep inside their half but they shuffle from side to side like a well-constructed yellow wall to deny Bayern at every turn.

Just over 10 minutes plus injury-time to go.

Can they hold out?

Bayern work a short free-kick and Kingsley Coman whips a ball towards goal. It's tipped over the bar by Alexander Meyer and the resulting corner comes to nothing.
