No side has ever won the WSL having lost more than two games, and Arsenal have now lost their third of the season.

All of Arsenal's substitutes with the exception of Amanda Ilestedt are warming up at half time. Laura Wienroither is in attendance and looks in good spirits as she nears a return from her ACL injury.

A frustrating first half for those Arsenal fans until an unmarked Alessia Russo met Steph Catley's corner at the back post and headed past Mackenzie Arnold to give the Gunners the lead.

Both sides line up for team photos while the team captains meet in the middle.

Here come the teams, led out by captains Mackenzie Arnold and Leah Williamson!

The teams are in the tunnel as Arsenal look to continue their perfect start to 2024...

And bubbles are being blown!

Both of West Ham's mascots are in attendance, a huge bear and some kind of scary hammer are trying to rev up the home fans.

Arsenal head back into the dressing room- I’m sure I spotted Lotte Wubben-Moy singing along to Town Called Malice. The pre-match playlist has been superb here.

Head over to @cardyfreddie on X (formerly Twitter) to see just how much of the Chigwell Construction Stadium is taken up by travelling Arsenal fans- they stretch from the halfway line all the way round to the far corner of the stadium.

Arsenal head coach is intently studying West Ham's warm-up from his halfway line vantage point. If the Gunners beat the Irons, they will move level on points with Chelsea at the top of the WSL- Emma Hayes's side play Everton in the late kick-off this evening.

A win for West Ham could take Rehanne Skinner's side up to 9th, depending on other results.

West Ham's important win over Bristol City last weekend saw the Irons move above bottom side Bristol, but are only two points clear of the relegation zone after the Robins drew with Aston Villa yesterday.

Speaking of the Conti Cup, defending champions Arsenal will travel to Dartford on Wednesday night to take on London City Lionesses in the quarter-finals.

Arsenal enjoyed a winning month of January, beating Watford in the FA Cup before WSL victories over Everton and Liverpool either side of a 6-0 win against Reading in the Conti Cup.

And now Leah Williamson leads Arsenal onto the pitch to loud cheers from the travelling fans.

The West Ham players have headed out to warm up at the Chigwell Construction Stadium.

Williamson and Catley replace Ilestedt and McCabe from the Arsenal side that beat Liverpool 2-0.

Leah Williamson makes her first start for Arsenal since April 19, 2023, and takes the captain's armband!

With the exception of McCabe and the injured Laura Wienroither, Teyah Goldie and Lina Hurtig, Arsenal have a full squad to pick from.

Arsenal will be without Katie McCabe, who picked up a fifth yellow card of the season in the second half against Liverpool last week.

Less than 15 minutes to go until we find out who starts for both sides.

Arsenal fans and players have arrived early and the supporters are in good voice. Over 1,400 have made the journey to Dagenham.

Good morning from Victoria Road! It's West Ham United versus Arsenal in the Women's Super League.
