Mount delivers and Roberts heads away deep in the Leeds box.

Chelsea quickly regather possession, though. Leeds just struggling to get on the ball at the moment.

Chelsea work the ball around the edge of the Leeds box before Chilwell shoots low past the post. Got a deflection. Corner to come.

Bamford back on now and moving a bit better.

Bamford is looked at and then helped back to his feet. He is limping off the pitch for further treatment.

Bamford is down in his own area and Chelsea do him a favour by putting the ball out. Looks like it was a challenge with Rudiger that did it.

Chelsea starting to take a bit more of grip on the game now. Most of the possession is with them as Leeds chase the ball.

Or maybe don't. The Chelsea corner is swung in and not met by anyone as it skips out of the box again.

Kante picks up the ball in midfield and drives on before firing a shot that deflects over the bar.

Leeds let in the softest of goals from a corner at West Ham last time out. Watch this carefully.

The Leeds press is relentless. But the Chelsea players are world class and still able to shift the ball about crisply.

Absolutely lacing it down now at Elland Road. Will the pitch stand up? Top pros can play on any surface, as this group of players is showing.

It is lashing it down now.

We've had a yellow card, it's grim and wet with two sides going toe to toe. This is what Leeds v Chelsea is all about.

Chilwell gets away down the left and crosses for Havertz, but his angled header floats harmlessly across the box to a Leeds man, who immediately gets his side on the front foot.

Roberts catches Jorginho down the back of the leg and is the first man in the book.

We had sunshine earlier and now we have rain.

It remains very much end-to-end, though. Bamford is just denied a header in the box by Rudiger as Harrison swings in the cross. Great defending.

Moments later, Pulisic's low cross is gathered by Meslier. The American is the man Chelsea are looking to hit more often than not.

Just had a quick scan through the Chelsea players and they are blowing. That's the thing about Leeds, they give you a proper work-out. Not seen a dull game of theirs all season.

You have to admire the work off the ball and the desire to go forward when it is won. From both teams.

Ziyech sees a shot from range blocked before Leeds break through Raphinha. His pass is flicked up by Dallas and then headed back to Mendy by a Chelsea head.

Joe Gibney: If Leeds vs Chelsea carries on like this, we'll be watching the game of the season.

Looks like Mendy got his fingertips to that Roberts chip. Brilliant save.

And now Leeds hit the bar!

Tyler Roberts and Patrick Bamford link up before the former chips a shot that beats Mendy and hits flush against the woodwork.

Can't take your eyes of this.

Chelsea are shifting Leeds around superbly. The movement up top is really impressive. Christian Pulisic is a big threat down the right, which he underlines with a low cross that Meslier has to palm out before Ayling completes the clearance.
