Anon: This Chelsea team has absolutely no attacking threat. When they do get into the City half they have no idea where to go or what to do and end up passing it all the way back to the keeper. I think it's time for Potter to find some new tactics or Chelsea to find a new manager.

Den: By the time Boehly makes the decision to sack Potter, we'll have been relegated and in the Championship. Just get rid of him now please!

Tom: This season is a write-off. Our injury list is abysmal and the only momentum we have currently is negative. We have never needed a proper six more than we do now. Develop youth, clear out unwanted players and go back to the drawing board. Once again, why Tuchel was sacked is more and more baffling as we go through the season. European cups have gone from a reality to a ridiculous dream.

Referee Rob Jones calls an end to the first half to put Chelsea out of their misery.

It has been a Manchester City masterclass against a truly woeful Chelsea side.

Riyad Mahrez opened the scoring with a sublime free-kick, Julian Alvarez added a second from the penalty spot after a clear and needless handball from Kai Havertz before Phil Foden finished off a delightful team goal for number three.

Marina: Kai Havertz continuing to be absolutely useless when playing as an out and out nine, except for being a detriment to his team. Hopefully new signing Fofana can turn the tide...

Kaustubh: Kai Havertz has been an absolutely atrocious player for most of his time at Chelsea. Some of his first touches in this match have been abysmal at best. Doesn’t press well, doesn’t score enough and zero consistency across seasons. Play a kitman as nine but not him.

Rob: Every single Chelsea player just doesn't seem bothered, how ever you see it, that is down to the manager, bring someone off (Havertz) to make a statement.

The faces of the Chelsea players say it all but they can't give up. There is a lot of disappointment in that team. This could get messy.

This one looks done and dusted already. Manchester City are cruising into the FA Cup fourth round while Chelsea have all the body language of a beaten side. Tough times for Chelsea and manager Graham Potter.

This could get really embarrassing for Chelsea - they haven't had one shot on or off target, they haven't even had a corner.

And it could've been 4-0. Cole Palmer plays it through to Riyad Mahrez who has been superb and been everywhere. This time he's on the left side in the penalty area, he sends it low and hard across the face of goal but a charging Julian Alvaraz just can't get a touch when sliding in.

The League Two club are very much in this.

Three leagues separate Aston Villa and Stevenage but the visitors have had a goal ruled out by a tight offside call and clipped the bar.

They're giving Villa a proper test but trail to a quality finish.

Briyan: If there was an option of forfeiting the match and awarding City a win I'd take it since the full-time score here could be embarrassing.

Charles: Chelsea lost this game an hour before kick off with that disastrous backline selection. Why does Potter make it harder for himself than it already is?

Teflon Don: Chelsea just walked onto that pitch to be severely beaten. There was no other plan.

It's super from Manchester City - they carved them open, switching the ball from one side to the other.

The most perfect City goal, the weight of pass from Mahrez, the cut-back and Chelsea's defence was just all over the place.

I think if Pep Guardiola has a scrapbook or a coaching manual of how he sees the perfect goal, that's it come to life.

Wow! We've seen some outstanding finishes this weekend and Luke Norris almost produces another. The Stevenage player is out wide when he beats his man before his curling attempt beats the outstretched hand of Robin Olsen and clips the bar.

Rob: You have to say if it wasn't for the fact that Chelsea are losing back to back against Man City...Potter would be looking at the sack! This Chelsea team is terrible.

Steve: Will Potter fall on his sword? He must have realised he is out of his depth. It's going to be harder and harder to get players in, in a competitive league when we are no longer competitive under him. TT should never have been sacked.

Neil: Memo to G Potter, you're getting sacked in the morning.

Immaculate. Top level stuff that we are seeing from City. Knocking the ball around with ease. City pick the right pass at the right time and Foden gets himself on the scoresheet as well. It really is the purest form of football.

Riyad Mahrez has already scored one free-kick and he takes this one. It's on target, but just above Kepa Arrizabalaga who sticks two fists up to punch it away for a corner.

Kepa then shows good handling to claim the corner.

Testing times for Stevenage. They need to get to half-time without conceding another but Villa have come alive after Morgan Sanson's goal. A chance falls to Leon Bailey on the edge of the box but he scuffs his attempt.

This is what you got to do. You have to your attacking midfielders going beyond and joining up with your forwards.

Stevenage will feel a little a hard done by. They haven't caused any real problems for Villa

Saidmadrid: Havertz handball was clumsy, no need to make things easy for City... Chelsea shooting themselves on the foot.

Camatriix: These Chelsea players don't look even slightly interested in playing for Chelsea.

It's all Manchester City and Phil Foden has a chance but, under pressure, the ball loops up safely into Kepa Arrizabalaga's hands.

The Spanish goalkeeper then has to make a save from a toe-poked effort from Julian Alvarez and now City have another free-kick on the edge of the area after Kalidou Koulibaly flattens Riyad Mahrez.

Chelsea all over the place.

Chelsea manager Graham Potter looked bewildered at that penalty award and his team now face a huge battle to stay in the FA Cup. Manchester City are in complete control and well on the way to a winning double against Potter's side inside four days.
