Arsenal grew into the game. They had good combination play and had some good chances. It has been like watching the Arsenal of old.

Arsenal responded well to falling behind, and this equaliser from Blackstenius was deserved.
The Swedish forward has looked like the player who tore United States apart at the 2020 Olympics today.

We've timed this at 96 seconds, Sam Kerr putting Chelsea in front.
It was all downhill from here for the Blues...

Jonas Eidevall has comfortably won the tactical battle so far. It has been a dominant performance from Arsenal and that third goal gives them a two-goal lead they thoroughly deserve.
The players went off down the tunnel at half-time in front of the Arsenal end and it's their players who had a spring in their step.
Emma Hayes was having a chat with Erin Cuthbert as they trudged back behind.

It has been an entertaining game. Arsenal have been the better of the two teams, they've put a show on in the opening 45.
Emma Hayes will be frustrated. She made a tactical change but it didn't work. Now she has to completely change her team talk.

Rachel Brown-Finnis
Ex-England goalkeeper on BBC One
What a sucker punch that is for Chelsea. They'd reshuffled and gone three at the back but can't prevent it.
What a sensational end to the half.
HT: Arsenal 3-1 Chelsea
The first major final of the season has not disappointed so far.
Certainly, this has been Arsenal's best 45 minutes of 2023. Plenty to do for Chelsea in the second half.

That goal was literally the final touch of the half.
Is that the killer moment?
Niamh Charles own goal
Wow!
Catley swings it in to the edge of the six yard box, Arsenal centre back Rafaelle rises above the crowd and nods it home.
Berger came to try and collect, but was lost in the crowd of her own team mates.
On second view, Niamh Charles appears to have got the final touch. It goes down as an own goal.

Maritz wins a corner for Arsenal. Likely the final chance of the half.

Kim Little and Leah Williamson will be telling their teammates to stay switched on. They are so experienced.

Cuthbert hangs it in high, Zinsberger came to gather but fumbled the ball.
However, the offside flag was already up.

Four minutes added on, after a couple of injury stoppages.
Chance for Chelsea to grab an equaliser? They have a free kick wide on the right.

Another good tackle by Little, this time on Scotland colleague Erin Cuthbert.
The Arsenal skipper has had a brilliant 45 minutes.

Another bold move from Emma Hayes to bring on Kadeisha Buchanan.
Hayes is not hanging around until half-time to change things up. That's a sign of how one-sided this has been.
Arsenal 2-1 Chelsea
So, Chelsea have gone to a back three with wing backs.
Will Arsenal adapt to meet the new system?

Straight into the wall. A waste.

Chance for Chelsea here, a free kick 25 yards out central.
Reiten stood over it.

The sub is made, centre back Buchanan on for attacking midfielder Jelena Cankovic.
Cankovic was dominant against Arsenal last week but has been anonymous today.

When you have Guro Reiten and Sam Kerr, you always have a threat.
The Chelsea duo combine again, this time Kerr's header is wide.
