Leroy Sane starts a good Bayern move with some quick feet in midfield but it ends with Lucas Hernandez's cross being cleared.

Serge Gnabry almost puts this to bed as he cuts in from the left but his shot is just over the bar.

Robert Lewandowski is close with a misplaced pass. He tries to find a team-mate with a shot from the corner of the box but it lands on the roof of the net. Roman Burki was worried for a moment.

Leroy Sane and Javi Martinez replaced Jerome Boateng and Kingsley Coman for Bayern.

Julian Brandt and Thorgan Hazard replaced Jadon Sancho and Gio Reyna for Dortmund.

Both sides make so many changes I can't even keep up with it. Thorgan Hazard was one of them and with his first touch he flicks the ball up and volleys towards goal but Manuel Neuer punches away.

Marco Reus bursts into life as a loose ball lands to him in the box. He cuts inside a defender but his shot is held by Manuel Neuer.

Corner to Bayern now as Gio Reyna's cross is blocked. He's had a good game.

Huge chance for Dortmund - and Manuel Neuer does make a save now.

Gio Reyna is in loads of space on the left but his side-footed effort is weak and Neuer pounces on it.

Bayern keeper Manuel Neuer hasn't actually saved a shot yet. Dortmund have only had one effort on target - their goal.

Here comes English teenager Jude Bellingham for Borussia Dortmund. Thomas Delaney is off.

Kingsley Coman almost wraps this one up for Bayern but his shot from a tight angle is well saved by Roman Burki.

Since joining Bayern in 2014-15, Robert Lewandowski has scored 30 Bundesliga headers.

No other player has scored more than 14 in that time.

So close from Kingsley Coman again for Bayern. He has a crack from the right wing - miles out - but Roman Burki claws it out of the top corner just before it crosses the line.

Erling Haaland has left his shooting boots at home. He holds off Jerome Boateng brilliantly but smashes a shot into the side-netting.

Robert Lewandowski (18) is the leading Bundesliga goalscorer in Der Klassiker (one for Dortmund, 17 for Bayern).

The Pole has netted 13 goals in his last eight Klassikers, scoring multiple goals in five of the previous seven matches.

Kingsley Coman almost puts Bayern two goals ahead but crashes an effort off the post from 20 yards out. Dortmund on the ropes.

Dortmund have a good chance at the start of the first half. Erling Haaland is onside from Jadon Sancho's pass but flashes a cross beyond everyone. Why didn't he shoot?

The second half begins.

That was Thomas Muller's 15th Bundesliga assist in 2020. No other player in the division has provided more than 10.
