Almost a chance for Liverpool as Trent Alexander-Arnold sends Mohamed Salah down the right. He tries one of outside-of-the-foot scoopy crosses he likes but Robert Sanchez catches it.

At the other end Leandro Trossard plays it across the box but nobody was there.

Should be two.

Saints' Adam Armstrong does brilliantly, crossing for Che Adams who heads the ball over the bar with the goal at his mercy.

A big let off for the Hornets. This game has really come to life.

Enormous let-off for Watford. Inside the six-yard area, Che Adams heads it down and over. Southampton have outpassed and outclassed Watford so far. The home side are really struggling.

Joao Cancelo's shot is defected over as City continue to knock on the door.

Newcastle are walking a fine line. Ziyech should have scored, no excuse. It's a good opportunity, almost an open goal.

Palace continue to frustrate City. They are almost allowing the home side to have the ball until they get anywhere near the box and then they kick into action, closing down and snapping into tackles and blocks.

You can feel the home frustration.

Sadio Mane's goal is disallowed by the VAR. He blocked the clearance with his arm. By the new-ish rules, that's not allowed.

Oh, what a miss!

Hakim Ziyech just has to side-foot in at the back post after Kai Havertz flicks on Reece James' cross, but he sends the ball spinning over the bar.

Don't think he expected it to come to him. A bit more composure and Chelsea would be ahead.

Off the line!

Watford thought they'd equalised.

Goalkeeper Ben Foster sends through Joshua King on the break and the forward crosses well to Ismaila Sarr.

Sarr's shot beats the keeper, but he's denied by a combination of the post and Kyle Walker-Peters blocking on the line.

You don't get closer than that.

Sadio Mane finds Roberto Firmino, who lets the ball run and then shoots - blocked by Lewis Dunk.

This is a good game. Could end 3-3 or 6-0.

It's almost like a training game for Chelsea at times. We haven't seen Mendy involved in the game at all. Newcastle just can't get out.

Manchester City fans are getting increasingly annoyed at what they perceive as time-wasting by Palace keeper Vicente Guaita.

We have played half an hour.

Over half an hour gone now and Palace are still ahead. They've defended really well to preserve it too.

Gabriel Jesus asks for a penalty as his shot pinballs off a couple of Palace defenders - Marc Guehi is one of them - but no way is that a pen.

All Southampton now.

And they have a free-kick in James Ward-Prowse territory....

...nothing comes of it.

Dennis: This goal scoring is getting too easy for Liverpool.

Khan: Wow, what a ball by the Ox. So happy for him, people forget how good he was before two bad injuries.

Johann Gudmundsson should double Burnley's lead. He's one on one with the keeper from about 50 yards out. The Icelandic player reaches the edge of the box and forces a decent save from Alvaro Fernandez.

Hakim Ziyech thinks he's just curled in a shot to give Chelsea the lead, but the flag is up against him for offside.

In the aftermath, referee Paul Tierney has another word with Karl Darlow. To paraphrase: get on with it.
