Both sides have really been getting stuck in, particularly in midfield. It's a good battle out there.

This is a good spell for the hosts. A good passing move from the Hammers sets up Emily van Egmond with a half chance, on the edge of the box. She's making some good runs from midfield, attacking the penalty area. This time, she can't beat the keeper.

West Ham lost four WSL games in a row before their comeback victory at Birmingham last weekend, but they look confident this afternoon.

Rachel Daly sends over a cracking cross that hangs up near the back post for Martha Thomas, who can't quite head it goalwards. Decent chance for the hosts.

Maya Le Tissier bombards forwards for Brighton and, from a very tight angle on the right, clips an effort just over the crossbar.

Martha Thomas is in a bit of pain, holding her shoulder, but she looks likely to continue.

West Ham's Martha Thomas gets through on goal, one-on-one with Cecilie Fiskerstrand, but the Norwegian makes herself big, gets out quickly to the edge of the box and makes the save.

Thomas will feel she should have scored.

West Ham's Australia midfielder Emily van Egmond tries an acrobatic effort from the edge of the box, looping the ball over her head with her back to goal, but it goes too high and drops on to the roof of the net.

Brighton boss Hope Powell and her assistant Amy Merrick both remain in isolation, after a staff member testing positive for Covid-19 around 10 days ago, so are following this game from home.

Their side have started well, looking to move the ball forward quickly when they get possession.

Later this afternoon, in Hertfordshire, Arsenal host defending league champions Chelsea and that's a game you'll be able to listen to live, via BBC Radio 5 live Sports Extra, at the top of this page.

The game's being played at a decent pace so far, but neither keeper has been forced in to a key save just yet.

Rianna Jarrett fires at goal for Brighton from long range, looking for her first league goal of the season, but her strike flies just wide.

The Hammers have won three of their four previous WSL games against Brighton, losing the other 4-0.

Everyone takes a knee and then Brighton, in their yellow away shirts and blue shorts, get this game started.

The players are out, in bright sunshine in the capital, but it's windy and chilly.

Both teams gather for one last pre-match huddle...
