Fran Kirby, Sam Kerr and Sophie Ingle are all coming on for Chelsea.
Arsenal 2-1 Chelsea
Vivianne Miedema is absolutely running the show. She slips it through to Beth Mead and she's denied from close range by Ann-Katrin Berger.
This has been a rapid start to the second half by Arsenal.

The reaction on the Arsenal bench was brilliant - fist pumping, the lot.
The reaction on the Chelsea bench? Tell Fran Kirby and Sam Kerr to go and warm up.
Arsenal 2-1 Chelsea
Beth Mead is away down the right this time and Ann-Katrin Berger has to come out of her box to smash it into the stands!
Beth Mead
Wow!
Lia Walti wins it back on the edge of her box. Vivianne Miedema then threads it through perfectly for Beth Mead and she races through the two Chelsea centre-halves.
She is clean through but checks back, takes her time, then curls it into the right corner.
That's another brilliant goal!
Arsenal 1-1 Chelsea
This was close! Guro Reiten floats it across the face of the goal and it ends up clipping the top of the crossbar!
Goalkeeper Manuela Zinsberger may have got a touch on it too.
Arsenal 1-1 Chelsea
England manager Sarina Wiegman is here by the way. There's plenty of players on show for her to take a look at.
Arsenal 1-1 Chelsea
Back under way for the second half.
Brighton v West Ham (14:00 BST)
Half an hour to go until it all kicks off at the Amex.
It's a nice day down in Brighton by the looks of it.

It wasn't a vintage Chelsea performance. There will be frustration because they haven't been able to break down Arsenal - as Arsenal have been playing exceptionally well. A really good battle, covered with real quality.
Potentially this was a chance for Arsenal, with the likes of Sam Kerr and Fran Kirby on the bench. Arsenal have looked as good, if not better, than Chelsea for large parts.
Brighton v West Ham (14:00 BST)
The team news for the second game of the afternoon is in. Brighton welcome West Ham to the Amex Stadium for their season opener.

Arsenal 1-1 Chelsea
A very good half. It's nicely poised at the break. The Arsenal players jog off down the tunnel quickly.
Arsenal 1-1 Chelsea
Arsenal almost respond immediately!
Beth Mead tees up Vivianne Miedema but she skews the shot wide of the left post.
That was a real chance!

A clinical finish from Erin Cuthbert. For all the pressure Chelsea might have been under, were they going to give up? No. They are mentality monsters, have turned the screw and found the breakthrough. It has not been perfect, it has not been the best version of Chelsea, but they have found a way.
Erin Cuthbert
Right on the stroke of half time.
Millie Bright's shot is blocked, it falls for Melanie Leupolz, she lays it off to Erin Cuthbert and the Scotland international drills it low into the far corner.
Brilliant finish.
Arsenal 1-0 Chelsea
Jess Carter does well to bring it out for Chelsea and it's sprayed over to Guro Reiten on the left.
It comes into Ji So-yun in the box but Leah Williamson makes an excellent last-ditch block! Crucial defending.

Madeleine Wedesweiler: Viviane Miedema has scored 15 goals in 9 games, name me someone in the men's comp that's done this?
Arsenal 1-0 Chelsea
Niamh Charles' cross is comfortably picked up by Manuela Zinsberger. She pumps it long and Beth Mead almost takes advantage of a sloppy header before Millie Bright recovers.
