Yep, West Ham are just starting to build again. Has Chelsea's moment to get a second passed?

West Ham have done well in killing the momentum of Chelsea.
The chaos that we saw in the opening 20 minutes has died down.
West Ham 0-1 Chelsea
And from the wide free-kick Pernille Harder heads Jessie Fleming's cross off target at the back post.
West Ham 0-1 Chelsea
West Ham defender Hawa Cissoko picks up a yellow for a very late shoulder barge on Sam Kerr.
It was risky too, a quick replay shows that she started making contact inside the box. Just a free-kick is given. West Ham get away with one.

What a fantastic save from Mackenzie Arnold. That impulsive save has kept West Ham in this game.
West Ham 0-1 Chelsea
Oh top save from Mackenzie Arnold to keep it 1-0.
Johanna Rytting Kaneryd chips the ball into the box and Pernille Harder is there to meet it volleying the ball goalwards.
But Arnold somehow gets a fingertip to it and tips the ball around the post. West Ham are still in this, just.

Chelsea are popping the ball around like it's a training game.
It's exhausting for West Ham as they chase the ball.
West Ham 0-1 Chelsea
Only a matter of time now. Jelena Cankovic gets in between the lines and almost catches Hammers keeper Mackenzie Arnold on her heels with an early shot that flies just over the bar.
West Ham can't get out.
West Ham 0-1 Chelsea
Beautiful football from Chelsea again as Pernille Harder, Sam Kerr and Jessie Fleming all link up but the latter can't direct a cross on the stretch towards a teammate and the ball dribbles out for a goal kick.
West Ham 0-1 Chelsea
Chelsea have had 70% of possession so far. Dominant stuff from the Blues.
West Ham 0-1 Chelsea
A second looks very likely. Chelsea continue to pass the ball around in dangerous areas.
West Ham 0-1 Chelsea
Another Chelsea penalty appeal as Jelena Cankovic gets in behind and hits the deck under a challenge from Hawa Cissoko.
Nothing given. I'd have give a pen for that. Cissoko was nowhere near the ball and seemed to just push the forward over.

It was coming.
The way Chelsea have built from the back was very patient.
What do West Ham do now? They haven't had a great season and it's going to be tough to get back into this game.
Niamh Charles
Chelsea go ahead.
Pernille Harder does brilliantly to get an attack rolling. The ball is eventually pulled back to Sam Kerr whose shot is blocked on the line but Niamh Charles is following up to tap home on the rebound on her 100th WSL appearance.
Chelsea are going top as things stand. Great start.
West Ham 0-0 Chelsea
First effort for West Ham as Dagny Brynjarsdottir whips in a cross and forward Viviane Asseyi meets it with a hooked volley that goes straight to Chelsea keeper Zecira Musovic.
The Hammers aren't here just to make up the numbers, they're sensing some weaknesses in this Chelsea side.

When Chelsea get Ingle or Flemming on the ball in midfield it's important that they look to change the angle.
At the moment they are just playing into West Ham's hands.
West Ham 0-0 Chelsea
West Ham are living dangerously, dropping further and further back.
There's some intricate passing between Sam Kerr and Pernille Harder but neither can find enough room to get a shot off and any chance of an opener goes begging.
West Ham 0-0 Chelsea
Right now it's Chelsea who look the likilier to open the scoring.
Pernille Harder wins the ball down the left but her shot is straight at West Ham keeper Mackenzie Arnold.

It's important that West Ham play at pace when they attempt to break on the counter-attack.
