Mahmoud Dahoud brings Kingsley Coman down on the edge of the area.

Do we have a penalty? The referee is taking a look a the screen...

Robert Lewandowski hasn't been short of chances today.

The ball is worked in nicely to the Pole at the top of the area. He has time to glance up and shoot, but it's a wild effort over the bar.

A careless challenge from Mats Hummels on Kingsley Coman gives away a free-kick in a dangerous area.

Borussia Dortmund are sporting a slightly new look.

They are in their famous yellow and black, but there is a significant twist to it today.

As part of the club's United in Diversity campaign, the sponsorship logo on the front of their shirt is rainbow coloured.

Captain Marco Reus is also wearing a rainbow-coloured armband today.

Considering they lead 2-1, you could say the look suits them.

Mats Hummels with a crucial, crucial block for Dortmund.

He throws himself in front of a Robert Lewandowski effort. It was a fierce strike.

And now Thomas Meunier follows the Bayern man into the book.

The Dortmund defender is cautioned for a challenge on Kingsley Coman.

And now Robert Lewandowski is first into the book for a foul on Mahmoud Dahoud.

Erling Braut Haaland is lurking for a hat-trick. Twice he is foiled on the edge of the area.

Bayern's defence is being stretched by the Norwegian.

Bayern really need Robert Lewandowski to fire this evening.

With 18 Der Klassiker goals, he has more goals in the fixture than anyone else. That's anyone else in history!

Seventeen of those goals have come for Bayern, while one was for Borussia Dortmund.

Missed chance, this.

Robert Lewandowski snatches at a shot after Leon Goretzka chested the ball down for the hitman.

Bayern Munich are finally finding their feet, one feels.

A deep cross from Joshua Kimmich on the left finds Leroy Sane at the back post. It's a great headed attempt, but he can only direct his effort over.

Talking about records...

Bayern are trailing 2-0 at home after the first 10 minutes for only the second time in the Bundesliga.

The last time this happened was 22 January 1977 against MSV Duisburg.

For the record, that match finished in a 2-2 draw.

Well, world, European and German champions Bayern were today looking to match a 50-year-old record!

A triumph today would be a fifth straight league win over Dortmund. The last time they managed such a run was between 1968 and 1970!

It would take something epic to see that happen now.

Hansi Flick will want to see his side's impressive run against Dortmund continue today.

Under the head coach, Bayern have a 100% record against today's visitors.

As it stands, they have it all to do. That early goal has the visitors buzzing.

Leon Goretzka takes a knock trying to meet a free-kick in from the left.

Marwin Hitz comes out to punch and gets plenty of the Bayern man as well. Fierce stuff.

These are the two highest scoring Bundesliga sides over 23 games this season.

Bayern lead the way with 67, while Dortmund have now hit the back of the net 49 times.

We have certainly just found out why we can expect goals in this one!

Bayern Munich get us up and running at the Allianz Arena.
