It hasn't been the most exciting of games.

21 minutes played: 0.00 expected goals for both teams.

West Ham have defended well and have started to engage players when they step into certain areas in front of the back line.

They will be frustrated to be going in at the break a goal down, especially as it was the second phase of a set piece.

Arsenal were getting frustrated, forcing balls and rushing things, but they got the goal from Alessia Russo. West Ham are still in this for me.

Ella Toone looks to charge forward, but she dawdles for too long and Brighton's defence run back.

She plays the ball to Geyse instead, whose cross is deflected behind for a corner.

Arsenal moving level on points with WSL leaders Chelsea as it stands.

Doing what needs to be done.

The referee hands a booking to Lee Geum-min for talking back to her.

Leah Galton replaces Lucia Garcia.

Man City haven't done much to trouble Leicester, but they did have 76.4% possession across the opening 15 minutes. Dominant.

Filippa Angeldahl has the ball on the edge of the Leicester box and tries to turn, but she can't get past the defence and instead knocks the ball out of play.

It just isn't working for City at the moment.

West Ham need to stay switched on here, because they will not want to go in 2-0 down at half time.

They have done well for the majority of the first half, have been disciplined defensively and will not want to have that work undone by another goal. At 1-0 they are still in the game.

Arsenal are purring now, passing the ball smoothly around until Steph Catley pings in a shot from the edge of the area and Mackenzie Arnold has to move smartly to keep it out.

Now the referee does hand out a yellow card.

Elisabeth Terland goes into the book for a foul.

Another foul from Poppy Pattinson on Geyse. Home fans are chanting "off, off, off".

Marc Skinner and assistant Charlotte Healy call over Leah Galton from her warm-up. It looks like she's coming on for United.

The referee has a word with Veatriki Sarri and Poppy Pattinson after a foul on Geyser.

They're both lucky to get away without a booking - especially Pattinson, who talks back to the referee for a while

It's an important finish from Russo.

Arsenal have dominated this first half and had many chances, so to make the breakthrough is key.

Mackenzie Arnold comes out to clear the ball for West Ham and doesn't make the connection, and the goal is left wide open. A great headed finish from Russo, who was left completely unmarked at the back post.

There was plenty of frustration at Poppy Pattinson's challenge on Geyse a few moments ago.

The United forward roared in pain near the touchline when she was clattered into and the crowd were on their feet protesting.

Nikita Parris had to be held back by Maria Thorisdottir because she had strong words for Pattinson.

Geyse responded by running at Pattinson with the ball straight afterwards and beating her.

Kerstin Casparij just spend a moment receiving treatment on the side of the pitch, but she's fit to continue and is back on.

City have started brightly but not done much to test Lize Kop yet.

Amber Tysiak needs some treatment but can carry on, but Jess Ziu is done for the day. She limps off and on comes Emma Snerle.

Geyse does well again to get in down the right-hand flank.

She beats Julia Zigiotti, but Zigiotti stays down after the challenge.
