Things are going very badly indeed for Max Allegri.

Beaten by PSG last week, denied a winner by VAR chaos at the weekend, and now losing at home.

David Nerez has put Benfica ahead in Turin.

Ederson almost makes a mess of a cross which could have given Dortmund an empty goal or a penalty. Close one.

Jude Bellingham has scored his fourth Champions League goal, the most ever by an English teenager in the competition.

Tonight is also his 18th appearance in the Champions League, also a new record by an English player under the age of 20.

What a talent.

Chelsea are pushing for a second. Jorginho sends a first time ball from the halfway line which Pierre-Emerick Aubameyang looks to chase on to, but Philipp Kohn in the RB Salzburg goal is off his line smartly and just gets to the ball ahead of the striker.

Extraordinary scenes at Ibrox!

Rangers' Jamie Sands brings down Giovanni Simeone in the area, and referee Antonio Lahoz points to the spot and sends off the defender.

McGregor brilliantly saved the penalty from Zielinski, before Napolitano tucked away the rebound.

However VAR saw some encroachment and the penalty had to be retaken - and McGregor saved the spot kick again, before Rangers cleared this time. Incredible.

All the latest here.

Erling Haaland, who has been very quiet tonight, controls a long ball and plays it to Julian Alvarez, who is crowded out by Dortmund's defence.

The first hour has not gone so well for Manchester City, so Pep Guardiola has made some changes.

Julian Alvarez, Phil Foden and Bernardo Silva are not bad replacements to call on.

Jude Bellingham (two) joins Frank Lampard (five) and Raheem Sterling (two) as the English players to score more than one Champions League goal against an English side.

City had been warned many times in this game. It was just that last ball needed, that bit of quality needed.

Bellingham is the only player that’s moving across the penalty spot, towards the near post and gets there before Ederson.

Triple change for City straight after that goal!

Phil Foden, Bernardo Silva and Julian Alvarez are on for Jack Grealish, Riyad Mahrez and Ilkay Gundogan.

Khvicha Kvaratskhelia caught the eye with his performance against Liverpool last week, and he came close here.

Rangers fail to clear a corner, and the Georgian slams a shot on goal which Allan McGregor beats away.

I would say Kvaratskhelia almost got his name in the headlines, but they would have to be some pretty long headlines.

Anyway, you can follow that game live here, external.

Raheem Sterling now has 250 goal involvements in all competitions in his senior club career (158 goals, 92 assists).

A very good spell by Dortmund.

Salih Ozcan plays a lovely ball out right to Thomas Meunier, whose cross is blocked for a corner.

RB Salzburg try to instantly equalise and Benjamin Sesko lashes at goal from a tight angle but it's always going well wide and Kepa Arrizabalaga in the Chelsea goal is not worried at all.

City midfielder Rodri is booked for a foul on England's Jude Bellingham.

Raheem Sterling might be the highest positioned wing-back many have seen for a while, but now we know why.

Potter-ball is up and running. It was a great run by Reece James down the right which got that move flowing.

Best chance of the game by miles and it lands to Borussia Dortmund captain Marco Reus.

Dortmund break at pace and Reus gets into the box, cuts inside Manuel Akanji, who slides to the ground, and then curls the ball just wide of the far post with Ederson rooted to the spot.

The second half at Santiago Bernabeu has started as the first ended - with the visitors on top.

Timo Werner comes close, played in down the left of the Madrid defence and only denied by the legs of Courtois.

Leipzig looking a lot better after being hammered 4-1 at home by Shakhtar Donetsk last week.
