It sums up the uneasy state of affairs at Chelsea that the new head coach winning his first match in charge was not enough to stop the mutiny. This was a controlled, clinical performance from Liam Rosenior’s second string, who strolled into the fourth round of the FA Cup after a 5-1 win over a game but limited Charlton Athletic, but once again the big talking point was the travelling support spewing venom in the direction of their unpopular owners.

Dissatisfaction with the project is not going away. It did not even matter when Rosenior looked at his bench with Chelsea 3-1 up in the second half and decided to give Estevão Willian a runout against tired, lowly Championship opposition. The Brazilian winger is one of the best young players in the world and his runs were soon making Charlton’s defenders dizzy, but even signings like Estevão have done little to sway the view of a fanbase united in opposition to an ownership almost four years in and still to convince naysayers that their unique project is going to work.

In other news

90+3 min: Penalty to Chelsea Estevao gallops through on goal after a slick one-touch move. He tries to go round Mannion, who makes a good save at his feet – but the referee gives a penalty. No VAR so it will stand.

90 min Three minutes of added time.

89 min Charlton have played their part in an enjoyable cup tie. Ultimately, as we expected, Chelsea had too much class, even after making eight changes.

86 min Estevao’s deflected shot from distance is pushed away to his left by Mannion. That was a more comfortable save.

Replays suggest Chris Kavanagh probably made the right decision on the Charlton penalty appeal, or at least that it wasn’t a clear penalty. I think Fernandez got his leg between Jones and the ball, after which Jones kicked through Fernandez’s leg and went flying.

85 min Charlton have a big penalty appeal turned down when Jones appears to be bundled over by Enzo Fernandez. No VAR so the referee’s decision is final.

85 min: Chelsea substitutions Wesley Fofana and Pedro Neto come on for Jorrel Hato and Alejandro Garnacho. Fofana is making his first FA Cup appearance since Leicester beat Chelsea in the 2021 final.

84 min Jorgensen is briefly out of his goal after scrambling across his area. Gillespie, way out on the left, cuts across a fine effort but Jorgensen has time to get back into his goal and save.

80 min Mannion makes a fine double save to deny first Estevao and then Enzo Fernandez. Chelsea have cut Charlton apart again and again since those two came on.

78 min Chelsea’s substitutes are creating chances almost at will. Estevao and Fernandez combine nicely to tee up Delap, who sidefoots tamely wide from 10 yards. That was a great chance.

75 min Fernandez clips a neat pass over the top to Estevao, who takes it in his stride and lashes a rising drive that is tipped over by Mannion. Excellent save.

74 min: Charlton substitution Amari’i Bell limps off with what looks like a hamstring injury. Isaac Olaofe replaces him.

71 min Estevao’s deflected shot breaks kindly for Enzo Fernandez, whose first-time shot from eight yards is kicked away by Mannion. Chelsea have their game under control.

69 min: Chelsea substitution Marc Guiu is replaced by Liam Delap up front. Enzo Fernandez coes on for Facundo Buonanotte.

67 min: Triple substitution for Charlton Macauley Gillesphey, Karoy Anderson and Joe Rankin-Costello replace Charlie Kelman, Conor Coventry and Greg Docherty.

66 min: Substitution for Chelsea Estevao replaces the impressive Jamie Gittens.

61 min A sharp cutback from Garnacho finds Caicedo on the edge of the area. His mishit shot is blocked and Santos hoofs the loose ball into the crowd.

61 min This is a really good spell for Charlton. Has Liam Rosenior taken Chelsea as far as he can?

58 min Campbell was in an offside position, standing in front of Jorgensen, when Jones headed the ball towards goal. There’s no VAR so it doesn’t matter, but it would probably have been disallowed by Stockley Park’s finest.

Jorgensen saved Jones’ header but I guess Chelsea would argue that, without Campbell’s presence, he would have seen it earlier and might have pushed it away rather than back out in front of goal.

56 min: Chance for Charlton! A cross from the left it headed across the face of goal by Leaburn. Bree swishes at fresh air – the ball was fractonally behind him – and Kelman’s shot was deflected behind for a corner.

53 min Garnacho almost silences the boos with a curling shot from 15 yards that flashes just wide of the far post. Nice effort.

52 min Campbell receives a short free-kick, runs at his man and stands up a deep cross that is headed wide by Jones. A very tough chance under pressure.

47 min Gittens drives a low cross that ricochets towards Buonanotte 10 yards out. He has a shot blocked and is then wiped out in the defender’s follow-through. Chelsea want a penalty but the referee Chris Kavanagh turns them down; there’s no VAR tonight but that wouldn’t have been overturned anyway.

46 min Charlton get the second half under way. No substitutions on either team.

An early Charlton attack ends with Tosin’s clearance ricocheting off a Charlton player and over the crossbar.

Half-time reading

Caicedo clipped a pass into the area towards Guiu, who headed it square across the area. Hato waited for the ball to bounce, 15 yards from goal, and belted it into the roof of the net. The replay suggested he might have shinned it; if so, his shinpad has a very big sweet spot.

45+4 mi n Garnacho, who is being booed with gusto every time he touches the ball for reasons that aren’t entirely clear, has another shot blocked.

45+1 min The impressive Gittens wanders infield and strikes a shot from 25 yards with his left foot. It bounces awkwardly in front of Mannion, who plunges to his left to push it behind for a corner.

45 min Garnacho has a shot from the angle that is blocked by Bree. There will be seven minutes of added time.

43 min When the corner is eventually taken, Bree plays it short, gets it back and swings in a cross that is headed clear.

41 min Campbell surges down the left to win a corner for Chelsea. Before it can be taken, Buonanotte needs treatment after taking a knee in the small of the back.

36 min Chelsea have pinned Charlton in their half for the majority of the half, though they still haven’t really got behind the defence. That’s not easy, in fairness, when Charlton are defending on the edge of their own area.

34 min Acheampong swishes a drive from 25 yards that is pushed round the post by the diving Mannion. Good save but one he’d expect to make.

31 min Carey nutmegs Andrey Santos and is bundled over by Badiashile, who has been booked and needs to be careful.

The resulting free-kick eventually breaks for Docherty, who smacks a shot from 15 yards that is well blocked by Andrey Santos.

Chelsea break, Docherty fouls Gittens and is booked.

30 min “I only hope that if Scott Martin ever suffer such an event that the paramedics, doctors etc don’t have to struggle through a huge crowd that are only interested in a game of football!” replies Paul Skinner.

29 min Gittens, Chelsea’s liveliest attacker so far, cuts inside onto his left foot but smashes over from the edge of the area.

26 min Tosin blooters over the bar from distance. For all Chelsea’s dominance, the Charlton keeper Will Mannion hasn’t had a huge amount to do.

23 min Completed passes: Charlton 17-174 Chelsea.

Wait, Chelsea have only played four more passes than Charlton?

22 min It took a few minutes but Chelsea are controlling the game now. Charlton’s counter-attacks have been few and far between, and overall Chelsea have had around 80 per cent possession.

21 min “Is it normal to stop a match for a medical emergency in the crowd?” writes Scott Martin. “That seems odd because it does not directly affect anything on the pitch. Can’t the stewards and medical personnel handle without delaying the match for everyone else?”

It’s the norm these days. Not sure when it started to become so, maybe around 10 years ago.

19 min Santos drags a shot wide from the edge of the D. Chelsea are starting to take control of the game, with Gittens particularly dangerous on the right wing.

16 min Gittens cuts inside from the right, then veers back outside Bell and blasts a shot from 20 yards that is beaten away by Mannion. Well struck but straight at the keeper.

16 min Buonanotte slips Docherty in midfield, then beats him a second time before lofting a neat pass into the area towards Hato. He doesn’t get enough power on his looping header and Mannion leaps to make an ultimately comfortable save.

15 min The match resumes with a Chelsea goalkick.

14 min Yes, there is a medical emergency in the crowd. Play has been stopped for around four minutes so far.

12 min For reasons that aren’t immediately clear, there’s a break in play and both teams are passing a football around to keep warm. There might be a medical emergency in the crowd.

9 min Campbell tries his luck from the edge of the area but slices well wide.

8 min Gittens runs at Campbell and fires a low cross that is spilled by the keeper Mannion. Happily for him, the loose ball is booted clear by Coventry.

7 min Charlton have started well and are putting Chelsea under a decent amount of pressure. Chelsea would love an early goal to take the sting out of the game.

5 min Badiashile gets an early yellow card for pulling down Leaburn, who was in the Chelsea academy until the age of 16.

4 min Campbell’s low cross from the left is put behind for a corner by Andrey Santos. Bree takes, Jorgensen punches a little unconvincingly but gets away with it.

2 min I got the Chelsea formation wrong: it’s a 3-2-4-1 with Garnacho and Gittens in wide positions.

Chelsea (3-2-4-1) Jorgensen; Acheampong, Adarabioyo, Badiashile; Caicedo, Santos; Bynoe-Gittens, Buonanotte, Hato, Garnacho; Guiu.

1 min For the first time in 19 years, an association football match between Charlton and Chelsea is under way. And there’s an appropriately lively atmosphere at The Valley.

“Yes, sometimes the underdog comes out on top,” writes Matt Dony. “But sometimes, despite 18 months of preparation and unprecedented feelgood vibes, the underdog loses 4-1. Anyway. I’m no expert, but from what I have seen, Rosenior seems like a good bloke. I wish him good luck. He’s likely to need it in the Chelsea set-up.”

Too soon, Dony, too soon. And if I somehow live to the year 2126 after embracing a lifestyle of green tea and 12 cold showers a day, it’ll still be too soon.

There is some synergy with Chelsea being the first Premier League club to appoint a black manager in Ruud Gullit in 1996. But it remains a sad fact that despite the league’s diverse playing pool, Rosenior is only its 12th black manager. That doesn’t reflect the level of talent out there.

I have spoken to several black former Premier League players frustrated by the lack of manager and senior coaching opportunities they have been offered. It is to Rosenior’s credit that after being harshly sacked by Hull when he missed out on the Championship playoffs, he took a different route with Strasbourg and has landed a top job.

Once upon a time, before he reached to the gate to the shining uplands, Liam Rosenior was a Guardian columnist. Here are some of the topics he addressed.
