Standing ovation for Burnley goalscorer Matej Vydra as he's replaced by Aaron Lennon.

Still awaiting the breakthrough.

Thiago Silva tries to do it all himself, running with the ball to the edge of the West Ham box before firing a shot that hits an offside Timo Werner.

Pedro Neto almost instantly involved on the edge of the box but he's denied by a good sliding tackle from James Tarkowski.

This is a big game for Wolves too, don't forget, in their bid for Europe.

Pedro Neto is on for Fabio Silva for Wolves.

Pretty much everyone thought Burnley were wrong to sack Sean Dyche and put a caretaker team in charge.

But it's working, isn't it?

Still unbeaten.

Matt: I would hate to think where we would be without James Ward-Prowse! Just a sensational footballer!

Declan Rice is immediately into the action, getting the better of Kai Havertz in midfield before being fouled.

Mike Jackson for England?

Burnley are buzzing now. And not just because of their bee mascot.

Turf Moor is bouncing and the Clarets are looking for a second.

Shane Long has a go from the edge of the box and draws a fine save from Robert Sanchez. Saints want the win now.

Burnley are two points above Everton as things stand.

Ashley Barnes replaces Jay Rodriguez.

Chelsea have woken up. So has Thomas Tuchel, who is off his bench for the first time to complain to the fourth official about what he thought was a foul. He applauds referee Michael Oliver very enthusiastically shortly afterwards.

Here comes Declan Rice after a long briefing from his coaches. Will Tuchel respond in kind?

Great shift by Mark Noble, by the way. Expert marshalling of the West Ham defence.

Declan Rice will play the last 30 minutes for West Ham. Her replaces Mark Noble.

Our Premier League stats feed says there was a VAR check for a red card for violent conduct - not given - a few minutes ago.

That check seemed to evade everyone's attention, I wonder if it was the incident where Nathan Collins held his face after a clash with Fabio Silva.

N'Golo Kante has had an effort. Trveor Chalabah has had a pop.

Chelsea are still plugging away but the Hammers defence is still on top.

Just how important is Ward-Prowse for Southampton?

Worth his weight in gold.

Do you think Thomas Tuchel had a go at half time? I've seen four more crosses already than in the entire first half.

Chelsea are much more threatening down both wings.

Big chance for West Ham!

Andriy Yarmolenko beats a man in the box and sets up Tomas Soucek near the edge, but his effort is blocked.
