A poacher's finish from Charles De Ketelaere, his fourth in the competition this campaign.

The Serie A side are cruising towards their first home win of this season's Champions League, having played out goalless draws with both Arsenal and Celtic and also losing 3-2 to Real Madrid.

Villa are still creating chances. Lucas Digne stands up a cross from the left side of the penalty area, it is too high for Ollie Watkins and also for Matty Cash, although the right-back can get some contact on it but can't get over the ball and can only loop it harmlessly into the gloves of Radoslaw Majecki.

Pep Guardiola said there was no update on Kyle Walker’s proposed move to AC Milan but confirmed new defensive signings Abdukodir Khusanov from Lens and Vitor Reis from Palmeiras are both ready to be thrown into Premier League action.

The pair are ineligible for Champions League action until the knockout stage, should City get there.

I was really hoping Duran wasn't coming on for Watkins. Emery rarely puts them both together but you couldn't imagine at 1-0 down he'd be taking Watkins off.

Unai Emery has seen enough. Off goes Leon Bailey and on comes Jhon Duran. Most of the season it has been either Ollie Watkins or Duran up front, now, after Villa fans have long been hoping for it, now it is Watkins and Duran up front.

Atalanta finally have their second goal.

Mario Pasalic taps in from close range after Juan Cuadrado's pinpoint cross.

After a VAR check for a tight offside, the goal stands.

No big complaints from Rogers for that challenge. There was contact but he has ran into the defender.

We have spoken about Leon Bailey getting the ball one-on-one with his defender and he has done that twice recently in this game and hasn't looked to go round him. That is not a good sign.

Emiliano Buendia, again impressing for Villa, slides a pass to Morgan Rogers but he is bumped off the ball by Thilo Kehrer and Rogers hits the turf.

Appeals for a penalty, but not given. Monaco get away with one.

Erling Haaland has revealed the lengths he has been going to in the search for improvement on his already remarkable Manchester City record.

Haaland, who has just signed a new nine-and-a-half contract at Manchester City, said: "I started measuring my sleep to make sure I slept really well and it's true - I slept really well."

In a very impressive, engaging performance here in Paris, it is clear the only sleepless nights Haaland is interested in are the ones he is planning to give the world's defenders over the course of that mammoth deal.

Monaco think they have a second goal after Maghnes Akliouche ran on to a pass and steered a first-time finish past Emiliano Martinez, but Akliouche's celebrations are instantly stopped by the sight of a raised assistant's flag. Offside. No goal.

Prince William is a famous Villa fan and he's among the crowd in Monaco.

A promising move for Villa. Ollie Watkins sprints down the left channel and Monaco are stretched. The ball is played back to Morgan Rogers on the edge of the box and he hits it with the outside of the right foot, but it flies just wide.

The home side thought they had doubled their lead but the goal is disallowed for offside.

Ademola Lookman slid the ball across the box to Charles De Ketelaere who finished from close range but Lookman was offside and the goal is chalked off.

Monaco start the second half. Can Villa turn this around and take a big step closer to the last 16?

Erling Haaland, speaking in Paris ahead of the Champions League meeting with PSG, insists he has no concerns about his or Manchester City's long-term future as they await the outcome of a hearing into their alleged 115 breaches of financial rules after signing a new nine-and-a-half year contract at the club.

City have strenuously denied the charges, and Haaland said: "I haven't thought about that. I am confident the club knows what they are doing. In the end I don't think I should speak about that too much.

"I have only been here two and a half years and I'm confident the club knows what they are doing."

This is the first time this season that Aston Villa have been behind at half time of a Champions League game, and only the second time they've trailed at any point of a match (also in their 1-0 defeat to Club Bruges in November).

Pep Guardiola speaking in Paris about his friend from Barcelona, and now PSG coach, Luis Enrique: "I want in my heart a horrible performance from PSG tomorrow so we can win but afterwards the relationship with Luis Enrique will always be there. We will be friends forever."
