Julian Ryerson is booked for the foul which started the melee and Niklas Sule and Mason Mount are shown yellow cards for their roles in it.

Lewis Keeffe: Chelsea's poor form is down to scattergun recruitment. £600m and there is deadwood and misfits throughout the team already. Dortmund Know what they want and it works. Huge credit to Dortmund.

The benches are involved too. A lot of stuff for the officials to digest here.

Melee. It's all kicking off.

Reece James crosses and his fellow full-back Marc Cucurella clatters a Dortmund defender while trying to reach it. A couple of minutes left.

Benfica have taken a giant step towards the quarter-finals, and it has been handed to them on a plate by Bruges.

Really tame effort, it is never troubling the goalkeeper. It is four or five yards wide in the end.

This free-kick feels like a big moment... and Hakim Ziyech then shoots it well wide.

A few savvy fouls by Dortmund tonight, Salih Ozcan is booked for shoving over Joao Felix 25 yards from goal.

Now Hakim Ziyech's drive is blocked by Raphael Guerreiro. Chelsea have had plenty of half-decent chances.

Reece James finds Enzo Fernandez, who picks out Joao Felix but the Portuguese loanee's shot is easily saved by Gregor Kobel.

Felix's finishing hasn't been great today. Story of his career, a cynic would say.

Niklas Sule gets a bit lucky here. Kai Havertz runs onto Mason Mount's through ball and behind Sule. The Dortmund defender tries to pull his shirt back and then slides in and just about gets the ball in the box. Could have been a free-kick and was inches away from a penalty.

Chelsea should have scored, they have created chance after chance. This time Kalidou Koulibaly finds on the penalty spot unopposed and he hits it straight at the goalkeeper. He makes half a save and it still needs to be cleared off the line.

Ten minutes to go and end to end. Hakim Ziyech has a shot saved at the keeper's near post and Dortmund go forward but Anthony Modeste lashes over from a tight angle.

Dortmund bring on English teenager Jamie Bynoe-Gittens, once on the books of Chelsea, for his Champions League debut. He replaces goalscorer Karim Adeyemi.

BRILLIANT goalline clearance from Emre Can saves Dortmund. Ruben Loftus-Cheek cuts it back for Kalidou Koulibaly, who blasts a shot towards goal. Gregor Kobel gets a touch but it squirms past him. It's just about to roll over the line when Can slides in to hook it away.

Hakim Ziyech's inswinging free-kick is punched away by the Dortmund keeper.

Karim Adeyemi is having to do a lot of defensive work now with Chelsea pushing for an equaliser. He's booked for fouling Hakim Ziyech.

Where Chelsea was most effective was when there was space in behind and Mykhalo Mudryk was able to use his pace to exploit that. The moment he became tired Chelsea looked less threatening.

Chelsea's top scorer in this season's Champions League, Pierre-Emerick Aubameyang, isn't even registered in their squad for this tournament anymore.
