That should be four!

Johanna Rytting Kaneryd is free inside the Arsenal box after being threaded through by Sjoeke Nusken, but Manuela Zinsberger does well to get off her line and block her shot.

A big save from the Arsenal goalkeeper.

Arsenal have a free-kick after Eve Perisset tugs Caitlin Foord's shirt.

Beth Mead sends in the delivery but nobody can meet it in the box.

Arsenal have a mountain to climb, but they're not giving up.

They've caused some trouble for Chelsea since the restart, particularly with their high press in the final third.

Beth Mead is swiftly back on the pitch anyway.

She fell into a member of the Arsenal staff after a collision with Lauren James.

Beth Mead has collided with the dugout and looks to have hurt herself, but she's off the pitch so play continues.

Jonas Eidevall opted to leave Alessia Russo on the bench this evening - but he's brought her on now.

Could she be the difference in the second half?

Arsenal made a triple-substitution at the break.

Emily Fox, Frida Maanum and Alessia Russo are on.

They replace Steph Catley, Victoria Pelova and Stina Blackstenius.

It had everything. Chelsea started on the front foot, looked like they were going to go super aggressive. Arsenal played their way back into the game, got on top and then Chelsea just hit them on the counter-attack and really made them pay for the mistakes they were making. It was a really relentless performance from Chelsea in the first half.

Mark, Swindon: From having an opportunity to put a dent in Chelsea's title charge, Arsenal have simply handed them the points. Awful first half performance.

Brian: Goal difference could still decide the WSL, so Chelsea shouldn’t stick at 3-0, with the start they’ve had, they need to be looking for at least a 5 goal win.

Martin: I thought Eidevall was redeeming himself in recent weeks. On this display, we need a change in the summer. He's leaving Chelsea open way too often, should be more than three.

There's potential [for Arsenal] to bring some real top players off the bench. Alessia Russo, Frida Maanum and Emily Fox seem to be going through a bit more of an intense warm-up than the other subs. That would be a real signal of intent for them to make a triple sub at half-time. They need to change something to get themselves back in the game.

Katie McCabe has been booked eight times this season - the only player with a worse record in a single Women's Super League campaign is... Katie McCabe with seven yellows and one red in 2021-22.

Lauren James is having a field day. I get the impression Emma Hayes has told her to play with a lot of freedom and almost have a free role, then it's up to the other players to fill in the positions she is leaving. Part of her game us trying to wind up the opposition and that seems to be working at the moment.

Chelsea take a big lead into the break. They're in total control.

Mark: Given the backing he's had is this really good enough from the Arsenal manager? Surely questions are going to be asked?

Steph Catley is off the pitch but the game resumes.

Lauren James sets herself up for a curling effort from 20 yards, but she doesn't manage to hit the target.

Steph Catley is receiving some treatment for a knee issue. She signalled to the bench immediately after going down.

A sign of Sjoeke Nusken's versatility is that she'd played at centre-back in Chelsea's past two games, owing to their injury troubles.

She's back in midfield today and has been involved in all three goals.

Three minutes added on at the end of the first half at Stamford Bridge.

Good effort from Reiten and we've seen her put those into the top corner. Zinsberger didn't move, she was just hoping for the best. She had no chance if that did find the top corner. It was just a little bit too close for Reiten to find the target.

Oooh.

Guro Reiten's free-kick beats the wall but ends up on the roof of the net, just not dipping quickly enough to hit the target.
