Bayern Munich 4-1 Dortmund as it happened: Thomas Tuchel makes winning start as Bavarians thrash rivals

This is too easy for Bayern! They're running away with it now!

Dortmund try and fail to play out from the back as they concede possession cheaply once more. Sane shoots from distance and Kobel can only parry it into the path of Muller who is left with a simple tap-in.

Kobel makes an important save to deny Coman... but the offside flag goes up and it's all in vain.

Coman is afforded space on the edge of the box but can't find the target with his shot.

Muller doubles Bayern's advantage! From a corner, he's in the right place at the right time as he bundles De Ligt's headed flick-on into the back of the net.

It's his 13th career goal against Dortmund and it's a long way back now for the league leaders.

Bayern are beginning to really purr now, as Goreztka aims a shot at goal that looks goal bound until it takes a deflection and the hosts settle for a corner.

Oh my, what a mistake by Kobel! It's an unbelievable howler from Dortmund's goalkeeper as he races off his line in an attempt to make a routine clearance from Upamecano's long punt forward but misses his kick!

The ball bounces into the back of the empty net and it looks like it's going to be an Upamecano goal!

An early blow for Dortmund as Can picks up an early yellow card. He will have to tread carefully now.

It sits up nicely for Davies on the edge of the box but he opts not to shoot and his pass is intercepted.

Reus drives into the Bayern penalty area off the right before seeing his effort deflected off the les of De Ligt.

Dortmund settle for a corner, which comes to little.

Goretzka draws the foul from Guerreiro as Bayern win the free-kick. Pavard flicks Davies' delivery into the box but Dortmund stand firm.

Dortmund win an early corner which is taken by Guerreiro. It's swung in to the near post but Bayern clear their lines.

Der Klassiker is up and running with Dortmund getting us under way in Munich.

Borussia Dortmund start the day on 53 points, top of the Bundesliga - just one ahead of Bayern Munich with the same number of games played.

With just nine league games remaining, today's result could be defining one.

Bayern have not lost at home to Dortmund in the Bundesliga since April 2014 - winning their last eight.

"What makes me particularly confident is the energy we have developed. This is because of our run, for example, and many good results," Dortmund boss Edin Terzic told reporters.

"We know our chance, and we want to take it. We have to do everything we can for that. We set out with the goal that we have to invest everything.

"We can send a signal - both to ourselves and to the competition.

"When you arrive at Bayern Munich in April and you are a point off the lead and in two quarter-finals, you want all the titles - this is the focus," Tuchel told reporters on Friday.

"We want a certain style of play, of course. But we have the chance for three titles - and we will fight for them."
