We've got another stoppage here, with West Ham's Anouk Denton receiving some treatment.

Alessia Russo has seven goals in the WSL this season.

Chelsea are totally dominant, it's just so easy.

Lucy Bronze pings the ball from the right-hand side and it's picked up by Sandy Baltimore on the left of the box.

She drives inside and shoots from a tight angle but the West Ham goalkeeper turns it behind.

Annabel Blanchard gives away a freekick in a promising area for Arsenal.

Katie McCabe steers an outswinger into the box but Palace clear it to safety.

Kinga Szemik is back to her feet and both sides use that stoppage as an opportunity to take on some instruction.

Another effort for Chelsea.

A cross comes in towards Mayra Ramirez, but it's straight at the keeper and a simple save for Kinga Szemik.

Szemik goes down injured.

Changes for both sides, with Ashleigh Weerden coming on for Mille Gejl for Crystal Palace.

Frida Maanum is replaced by Caitlin Foord for Arsenal.

This has been so easy for Chelsea so far. They're all over West Ham and having so much freedom, playing through the hosts and constantly getting in behind.

One-way traffic.

It should be 2-0.

Aggie Beever-Jones races down the right and cuts the ball back to Catarina Macario.

She's just netted an incredible finish. She slices this opportunity over the bar from seven yards or so.

Arsenal goalkeeper Daphne van Domselaar is called into action for the first time in the second half, plucking a cross out of the air.

Her goal-kick unleashes Alessia Russo but nothing comes of the move.

That could have gone anywhere!

Arsenal surge forward once again and the ball ricochets around Palace's six-yard box before being scrambled clear.

You sense a second goal can't be far away.

Ooooh. Millie Bright flicks a corner towards the middle of the box, but Sjoeke Nusken can't quite control the ball in time and the Irons manage to recover before she can put it away.

Arsenal have once again come out of the blocks firing, dominating possession in these early exchanges and getting forward down the left with Katie McCabe. Her cross is well snuffed out by Palace's defenders.

Chance! The ball comes out to Aggie Beever-Jones as West Ham fail to properly clear at the back. Her effort strikes a defender and swerves towards the corner, forcing Kinga Szemik to palm it behind for a corner.

Nothing of note comes from the set piece.

Good start from the visitors, attacking with numbers. Caterina Macario, Mayra Ramirez and Sandy Baltimore are already proving a real handful with their moves down the wings.

And we're off.

The players are back out at Meadow Park and we're about to get under way.

Arsenal lead 1-0 but Crystal Palace grew into the first half and showed good defensive shape to keep themselves well and truly in this WSL clash.
