WSL leaders Arsenal make it four wins out of four by beating Chelsea 5-0
Vivianne Miedema and Jordan Nobbs both score twice
It is Chelsea's first home league defeat since July 2016, a run of 25 games
Manchester City defeat West Ham 7-1 in earlier game
Nikita Parris and Georgia Stanway score two goals each
Nikita Parris has been on fire this season.
Here's the moment she capitalised on a West Ham defensive error to nod home.
Remember, you can watch this ongoing rout at the top of this page or via the BBC Red Button.
Man City Women 3-0 West Ham Women
Caroline Weir floats a superb corner right through the six-yard box and Jill Scott is closest to it, but the England international can only flick her header wide of the post.
Weir has been outstanding so far.
Here's the opener...
What a strike it was by Caroline Weir!
Man City Women 3-0 West Ham Women
Brianna Visalli sends a shot over the top for West Ham after a corner is only half-cleared.
It's better, but not quite the precision the hosts have shown at the other end.
Manchester United Women 1-0 Charlton Athletic Women
Casey Stoney's side lead Charlton 1-0 at half-time in the WSL Championship - but they had to survive a late first-half scare as Elizabeta Ejupi's header rattled the bar for the Addicks who, like United, are unbeaten in the league this season.
Ejupi's former team Aston Villa - without a point after three games and thrashed 12-0 by United in the season's opener - are locked in a 0-0 stalemate with Durham at half-time of the other Championship noon kick-off.
Man City Women 3-0 West Ham Women
We've just seen footage of West Ham head coach Matt Beard looking through his tactics booklet.
"Concede three goals inside the first 17 minutes," probably doesn't feature, I guess.
Nikita Parris

Caroline Weir turns brilliantly and slides the ball through for Nikita Parris.
England international Parris rounds Becky Spencer and slots into the empty net for her sixth of the campaign.
We've played 17 minutes and surely this game is over as a contest already.
Quote Message"It's important Manchester City keep pushing on. It's a great start but even at 2-0, if West Ham get one they'll feel like they're right back in the game. Man City just need to keep possession."
Kelly Smith, Former England international on the BBC Red Button
Nikita Parris
This isn't going to plan for West Ham.
A horrible attempted clearance from Ria Percival puts the visitors in all sorts of trouble and Nikita Parris pounces.
The WSL top scorer sends a clever back header looping over Spencer and into the net. That's five for the season already!
Caroline Weir

Caroline Weir advances into the penalty area and slams a bouncing ball into the top corner on the half-volley.
West Ham keeper Becky Spencer had no chance!
Manchester United Women 1-0 Charlton Athletic Women
While Manchester City has only just kicked off against West Ham in the WSL, cross-city rivals United are well underway against Charlton Athletic in the WSL Championship - and they are already a goal to the good.
Katie Zelem has curled past Addicks keeper Katie Startup to put the table-toppers - who have also had a Kirsty Hanson goal disallowed for offside - well on the way to maintaining their unbeaten league start.
There was a nice touch before the game as seven-year-old Darcy Yarnold - whose story went viral after she was picked on while playing mixed football - led the United team out as their matchday mascot.

Man City Women 0-0 West Ham Women
There's a healthy crowd inside the Academy Stadium, who have certainly braved the elements.
The first WSL match of the day is now under way.
Quote Message"We've had a tough start and it doesn't get any tougher than today, but we are embracing the challenge. We're finding our feet and getting better with each game and we believe we have the quality in the team to hurt Manchester City."
Matt Beard, West Ham head coach
England international Scott passed fit
Man City Women make two changes from their 3-2 victory over Birmingham City last time out, with Esme Morgan and Claire Emslie recalled, replacing Abbie McManus and Georgia Stanway.
Jill Scott has recovered from the ankle injury that forced her to withdraw from international duty with England and she starts for the home team.
Image source, Getty ImagesAs for the visitors, they've made just one change following their 2-1 win over Yeovil Town Ladies.
Forward Esmee de Graaf drops to the bench, with US defender Brooke Hendrix taking her place, possibly hinting at a change of shape for the London club.
Here are your two teams at a wet and windy Academy Stadium in Manchester.
Man City Women: Roebuck, Morgan, Beattie, Houghton, Bonner, Scott, Walsh, Wullaert, Weir, Parris, Emslie. Subs: Stenson, Nadim, Stanway, Park, McManus.
West Ham Women: Spencer, Percival, Simon, Hendrix, Flaherty, Ross, Simic, Rafferty, Longhurst, Visalli. Subs*: Moorhouse, Sampson, Kmita, De Graaf.
* Yes, that's right, West Ham have only named four substitutes.

Chelsea v Arsenal (14:00 BST)
Image source, The FAFollowing the game at Man City, we'll turn our attentions to matters at Kingsmeadow, where there's a tasty-looking London derby in store.
Defending champions Chelsea have something of a point to prove, after drawing three of the first four games of their title defence.
And Arsenal arrive in South West London in red-hot form, having won all three of their matches so far in style, scoring 16 goals in the process.
It should be a cracker, and could help shape the narrative of this season's title race.
There's actually a full fixture list in the WSL today, with five matches in total across the afternoon.
Stay tuned for updates from:
Man City v West Ham (12:30 BST)
Man City can go top of the table with a victory over West Ham this lunchtime, for an hour or so at least.

Meanwhile, West Ham are looking to build on their first win as a top-flight side which came last time out against Yeovil.
