Rodrigo with another angled shot saved by Edouard Mendy. He took it early. He had other options too.

It all came from more fine work by Brenden Aaronson, nicking the ball before shimmying past Conor Gallagher in midfield.

Thilo Kehrer is the first player to concede a penalty on his Premier League debut for West Ham since Jose Fonte against Manchester City in February 2017.

Vladimir Coufal finds West Ham team-mate Tomas Soucek with a clipped ball over the top but his ambitious volley from a very tight angle goes predictably wide.

Raheem Sterling one of best player for Chelsea, looks so lively and had the ball in the net already today. Taking great positions, could do with a little bit more help.

Close!

Leeds threaten for the first time in a while as Diego Llorente rises highest to loop a header from a corner on to the roof of the net.

Let-off for West Ham from another Brighton corner. Adam Webster flicks the ball on with his head but Joel Veltman misjudges his jump and doesn't make contact with a simple header six yards out.

Chelsea starting to take control now.

Leeds are still buzzing around after the ball, but the Blues look a bit more settled, more composed.

West Ham clear a corner as far as Brighton's Moises Caicedo, who has a crack from 25 or 30 yards out, but it's deflected wide.

From the resulting corner Leandro Trossard stabs a clever volley just wide.

Good spell for Brighton.

Pat is spot on with that. Conor Gallagher is a livewire but Leeds are matching fire with fire. Tyler Adams is the latest to track him and win a goal-kick off the Chelsea man as he sought to cross.

Leeds putting pressure on Conor Gallagher, giving him no time at all.

This is an important day for him, he'd like to play the Mason Mount position, but what Chelsea needs is someone in a more defensive position.

Mount is breaking into good positions, easing into the season.

Pascal Struijk charges into the back of Ruben Loftus-Cheek and sends him spinning to the turf. It's a heavyweight clash between those two. Also a little bit of retribution in that for the late knock the Chelsea man left on the Leeds defender early in the game.

West Ham win a corner but Kurt Zouma's header loops into the air and Robert Sanchez catches it.

It's a fascinating contest. For all the huff and puff and effective pressing for the home side, it is the Blues who have had the best chances, though.

Sterling could have scored, as could Mount. They look a threat every time they get the ball at their feet in the final third.

Brighton have avoided defeat in their last 15 matches when scoring the opening goal in the Premier League. But the last time they did lose after scoring the opener was against West Ham on 15 May 2021.

Save!

Chelsea break after winning a key header. Mason Mount drives and keeps going until he opts to shoot low towards the corner.

Illan Meslier dives and tips it superbly past the post.

Not the Premier League debut Thilo Kehrer would have hoped for. Alexis Mac Allister to take.

Rodrigo is looking sharper than at any time in his Leeds career. He latches on to a ball and finds himself with an angle to shoot. He drags his effort a touch, though, and sends it past the far post.
