Sevilla lead Borussia Dortmund 1-0 thanks to Tanguy Nianzou's header from Ivan Rakitic's free-kick.

A Sevilla win would make City wait to book their Champions League knockout place.

A quiet night for both goalkeepers so far, they've not been called into action once yet.

AC Milan have been more aggressive in a pressing sense this week. They are taking a chance and not sitting there asking to be beaten.

Ismael Bennacer steps on the ball and falls over, allowing Mateo Kovacic to nicks the ball away in a very dangerous position.

But the referee blows for a foul by the Chelsea man.

Never, poor decision that.

First goal of the 20:00 BST games as Salzburg lead Dianmo Zagreb thanks to Nicolas Seiwald's drilled effort from the corner of the area.

The Austrian side are top of Chelsea's group.

Raheem Sterling is looking to cause issues to the AC Milan backline for the first time, jinking into the box but is then halted in his tracks by ex-Arsenal midfielder Ismael Bennacer.

Now he would love to score against his old rivals tonight.

A bit of pinball from the corner but AC Milan manage to clear.

The hosts then break with pace, but Chelsea defenders retreat quickly to snuff out the danger.

Half of AC Milan's outfield players tonight previously played for Premier League clubs.

They include ex-Blues men Fikayo Tomori and Olivier Giroud.

But it's former AC Milan striker Pierre-Emerick Aubameyang who is looking to pounce for the first time, forcing Matteo Gabbia to concede a corner.

Andrei Shevchenko, who played for both of these sides with varying success - AC Milan good, Chelsea not so good, is watching on in the stands.

What a striker he was.

Italy boss Roberto Mancini is in the house too.

PSG

PSG sporting advisor Luis Campos to RMC Sport: "It's a categorical denial on our part. Whether he's happy or not, that's a question you have to ask him. It's a very personal question. I see Kylian working. Kylian is an extraordinary professional. For example, he played sick in the last match in Reims, he made the effort for the team. I see Kylian arriving with his teammates, happy every day and with a huge desire to work.

"I'm very surprised because I'm with Kylian Mbappe every day and he never asked me, and I just asked the president, he never asked to leave in January. I don't think that he thinks about it because if he thinks about it, he's going to tell me. He never told me, I know he never told the president, that he wants to leave in January. It is information, it's not a statement, you have to be very clear, which comes out a few hours before a very, very important match for us. It's important to come in front of the press and that's why I'm here. We have rumours every day, it's normal when you have three of the five most important players in the world. It's normal to have rumours.

"In my opinion yes [he's staying in January]. He never said anything to me. Or to me... And I just asked the president the question. For me it's clear that Kylian Mbappe is staying to follow his contract with PSG."

AC Milan are firmly on the front foot in the early exchanges, the new Pirlo Sandro Tonali whips in a free-kick which Trevoh Chalobah heads away at the far post.

Chelsea boss Graham Potter looking very smart on that touchline, a black turtleneck jumper with a blue blazer.

He wouldn't look out of place on a catwalk in the city.

Manchester City

Manchester City's Rodri, who had a goal disallowed, tells BT Sport: "With a very early red card, it's difficult for the team but we fight until the end and we had chances.

"We wanted to come here to win and it's frustrating. It's an important point and we keep going. We want to win but how we played 10 against 11 we can't be sad."

On his goal being disallowed, he said: "A bit frustrating, of course. No-one realised what is happening, they said it was a handball, I don't know if it was intentional. It was a mess.

"Then we had a penalty, we miss, then the red card and it completely changes the game."

Away we go in Milan.

The teams enter into the cauldron of the San Siro. Champions League nights are just not the same without the Rossoneri in the competition.

Here's a reminder of the line-ups...

PSG are without Lionel Messi - and rocked by the news that broke earlier today Kylian Mbappe wants to leave - for tonight's home game against Benfica.

Real Madrid would book their place in the last 16 with a point against Shakhtar Donetsk in the Ukrainian side's temporary European home of Warsaw.

Borussia Dortmund will go through with Manchester City if they beat Sevilla.

The other game sees Dinamo Zagreb host Salzburg in the Champions League's closest group. Zagreb are bottom but would overtake leaders Salzburg with a win.

Chelsea

Chelsea have not won on their last seven visits to Italy in the Champions League.

Their last success there came in November 2003 when Claudio Ranieri's men thumped Lazio 4-0.

That came just months after Roman Abramovich's takeover of the club and changing the face of English football with a £150m splurge on new signings.

Summer acquisitions including Adrian Mutu, Juan Sebastian Veron, Hernan Crespo, Damien Duff, Glen Johnson, Wayne Bridge and Claude Makelele were all involved in that game.

Chelsea defender Thiago Silva makes his 100th appearance in the Champions League tonight.

He becomes the fifth Brazilian to reach the landmark after Roberto Carlos (120), Dani Alves (111), Fernandinho (103) and Marcelo (102).

Chelsea

Two wins with two teams - Graham Potter couldn't have asked for a better week as Chelsea manager.

Success at Crystal Palace on 1 October had come in the last minute after a mediocre showing, but the victories in midweek and on Saturday were far more complete - and the fact that seven out of 10 outfield players changed between the matches made it all the more impressive.

Neither AC Milan nor Wolves put up much of a fight, but Chelsea saw them off professionally. They scored three, conceded none, and were then able to take it easier and make substitutions. Those changes meant important minutes for squad players and youngsters, adding their excitement to the rapidly growing positive feeling around the club.

The difficulty will go up a notch this week with two away games, but the improving mood means confidence at the training ground and in the stadium is growing.

It can all be shattered easily, but there's a strong sense that if the new head coach can keep winning his way through these first few months, the doubts about his credentials will evaporate.

He will have earned the trust of the players and fans to go with the support from the ownership which appointed him.
