Thomas Tuchel (10) has already surpassed Frank Lampard's longest Premier League unbeaten run as Chelsea manager: nine from September to December 2020.

This unbeaten run is the longest for Chelsea since they did not lose any of their opening 12 league fixtures under Maurizio Sarri (August to November 2018).

It's also the first time Chelsea have kept four consecutive Premier League clean sheets since December 2017 under Antonio Conte.

James: I hate to say it but I think Tuchel's got his subs wrong today. Giroud should have came on for starters.

Bebarters: For all the defensive improvements Tuchel has brought, Chelsea’s final third attacking play has substantially worsened.

Discorus: Have we actually improved since Frank left? Defensively more sound, but going forward we're woeful.

Thanks Dawkesy!

Good afternoon everyone. Hopefully we get some goals in this one at least. Here's a reminder of the team news if you're just joining us...

With that, I'll hand over to Emma Sanders, who will guide you through Crystal Palace v West Brom.

I was sure this wouldn't end 0-0. Certain of it. I was wrong.

Three minutes was the added time. We've had two of them.

The corner is allowed to bounce and met by Werner but his looping header is cleared by Phillips.

The 90 minutes are up. Haven't seen a board so not sure of how much added time still to go. Werner's shot is blocked behind for a Chelsea corner.

Opta inform me that no player has been subbed on and subbed off in a Premier League game on more occasions than Leeds United's Rodrigo this season (2, also v Sheffield United in September and level with Burnley's Robbie Brady).

Not a record any player wants.

Callum Hudson-Odoi shows some superb footwork to skip inside a couple of challenges before firing a low shot that Meslier is behind to save.

If Chelsea are guilty of anything this afternoon it is shooting too close to the Leeds keeper.

A flag goes up to halt a Leeds attack, with Roberts adjudged to have been offside. I'm not sure he was, though. Are we not supposed to wait for the attack to finish before flagging? Who knows anymore?

Christian Pulisic didn't look too happy about coming off earlier. He's looked good in parts of the game, but maybe lacking some match sharpness.

Thomas Tuchel has given Leeds director Victor Orta another stern look from the technical area, and the referee Kevin Friend has just told the Leeds coaching staff not to shout at him, given he can hear them fine with no fans.

Some interesting exchanges this afternoon.

Into the last 10 minutes. Leeds have come back into the game a bit recently. But Chelsea continue to look the more menacing.

For a second, Callum Hudson-Odoi looks to be away but his touch lets him down, allowing Meslier to come and gather. Flag was up too.

Interesting. Mateusz Klich comes on for Rodrigo, himself a substitute. Bielsa has no qualms about doing such a thing, regardless of players' feelings. Rodrigo is still working his way back from an injury too.

Chelsea also make another change with Callum Hudson-Odoi on for Mount.

Oh, almost an opening goal for Leeds. Chelsea do well to clear a corner and then Alioski's follow-up cross, but as Leeds come again James flicks Llorente's shot over his own bar.

Two corners follow, the first flicked behind by James again as Ayling looked to head in at the near post, the second nodded straight at Mendy by Rodrigo.
