More changes, Everton's Hayley Rasso is replaced by Alisha Layman and Nicoline Sorensen makes way for Ingrid Moe Wold.

Chelsea also make some a swap as Sam Kerr is replaced by Guro Reiten.

Valerie Gauvin is on for Simone Magill and the Everton forward almost instantly pulls a goal back, rising highest to head an out-swinging cross just over the bar.

Everton are getting closer.

That Jamie-Lee Napier chance was just about the last action of the half.

Emily Murphy's early strike sees Birmingham hold the advantage at the break.

What a chance for Birmingham to double their lead!

Emily Murphy drives forward, weaving her way through a sea of defenders and slides a pass towards Jamie-Lee Napier.

There's a bit of luck as the ball breaks for her off a defender but she then lashes her shot off target from the edge of the box. Should have done better.

Gilly Flaherty has resumed, by the way, wearing a big bandage on her head. Claudia Walker is yet to return.

Aileen Whelan's goal is the difference at the break.

That's half-time. Manchester City fully deserving of their lead.

West Ham 0-1 Birmingham

A really nasty clash of heads between West Ham's Gilly Flaherty and Birmingham's Claudia Walker leaves both players needing lengthy treatment.

There's a fair bit of blood on show. Both players are being bandaged up.

Attack vs defence in Bristol as Manchester City's Esme Morgan sees her shot blocked by Laura Rafferty.

Less than a minute until the break.

Tinja-Riikka Korpela, who is standing in for the injured Sandy MacIver, is having an excellent game by the way.

The Everton keeper has already saved a first-half penalty and plenty of one-on-ones tonight. That Kirby stop is probably only her fourth best save so far.

All that Everton possession but it's Chelsea who create the first meaningful chance.

What an opportunity for Fran Kirby to grab her second.

Niamh Charles puts the forward through with a defence-splitting pass but Kirby can't beat Tinja-Riikka Korpela who saves with her feet.

West Ham have improved as we get closer to half-time but they're still to truely test Birmingham keeper Hannah Hampton.

Only routine stuff for her to deal with so far.

Everton have started the second period much brighter and have had a string of corners headed away.

The Toffees are up for this.

Second half kicks off in Liverpool.

Everton have work to do.

So nearly three, as Lauren Hemp looks to round Bristol City keeper Sophie Baggaley.

Outside of her area the highly-rated stopper makes a perfect sliding tackle to win the ball.

Had to get that right. She was the last defender!

Aston Villa 0-1 Brighton

It looks like Aston Villa keeper Lisa Weiss picked up a big knock in the build up to that goal.

After a lengthy delay she's back on her feet. Expect plenty of time to be added on in the Midlands.

Birmingham are playing with such intensity - they are first to every ball. That's something Olli Harder will want to see from his West Ham side.

Carla Ward's side remain on top and deserve their lead.

Bristol City are growing into this game with plenty of possession.

But the moment they cross the halfway line City's press goes into overdrive and before you know it Gareth Taylor's side have the ball back.

Manchester City are so scary when they're in full flow. I can't see how Bristol City get the ball into their opponents box, let alone score against them.
