A double change for Chelsea to help that. Cole Palmer and Raheem Sterling go off, with Reece James and Noni Madueke coming on.

This is all about game management from Chelsea now.

Nothing daft at the back (cc. Robert Sanchez), take the sting out of Arsenal's resurgence in the middle and maybe nick something on the counter.

There is a nervousness around the stadium now. I've mentioned it before, but Arsenal always finish strong, so let's see if they can finish strong enough today.

Not sure if these changes were already planned, but Mikel Arteta throws more attacking dice at this one.

Kai Havertz - how much on the ex-Chelsea man coming back to haunt his old club? - and Leandro Trossard replace Martin Odegaard and Gabriel Martinelli.

All of a sudden Arsenal have a lifeline. The Chelsea keeper at fault there - but both keepers have been bad today. It was a great finish. He went for it first time and it worked.

Back in west London, Chelsea are looking to manage the game sensibly and claim what would be a statement win.

The home fans are vocal and happy with how things are going.

About 15 minutes left.

Manchester United fans are already arriving at Bramall Lane, looking sombre as they process the loss of one of their club's all-time greats in Sir Bobby Charlton.

United skipper Bruno Fernandes will carry out a wreath in memory of Sir Bobby when the players walk out for tonight's match.

The problem for Arsenal as they chase the game is the real threat of being picked off on the counter.

Raheem Sterling and Nicolas Jackson almost get in each other's way as the ball comes into the Arsenal box, moments before Cole Palmer drags a shot wide.

Now is the time for Mikel Arteta to make some changes which he hopes will turn this match around.

Gabriel Jesus, who has only had 27 touches and none of great significance, and Jorginho go off, replaced by Eddie Nketiah and Emile Smith Rowe.

This would have been an incredible introduction... Nicolas Jackson is put clear after Chelsea clear a corner and counter.

The Blues sub tries to round David Raya, but the Arsenal keeper does well to stand up and claim the ball with impeccable timing.

Changes are incoming - but not from the Arsenal bench.

Instead it is Mauricio Pochettino who is being proactive as he looks to preserve this lead and claim three vital points.

Goalscorer Mykhailo Mudryk is the man who is coming off, receiving a rapturous ovation as Nicolas Jackson comes on in his place.

Gabriel Jesus winces as he climbs to his feet and tries to jog off the issue which is bothering him.

Arsenal's issue is they haven't looked like scoring. Not a single shot on target yet.

A pause in play as Arsenal striker Gabriel Jesus receives treatment after a collision with Chelsea keeper Robert Sanchez.

The television cameras pan to Arsenal keeper David Raya, which tells you exactly what is one of the game's main talking points.

Penny for Aaron Ramsdale's thoughts. Sure he will be watching, hopefully back home with his newly-arrived son tucked under his wing.
