At the other end Sam Kerr beats the offside trap but her shot from a tight angle is saved by the legs of Arsenal stopper Manuela Zinsberger.

Credit to Arsenal, they have come back into it [after the goal].
They have realised that they need to get higher up the pitch, and if they do that they will create chances.
Chelsea 1-0 Arsenal
Nearly the leveller for Arsenal.
Frida Maanum tests goalkeeper Ann-Katrin Berger with a strike from the edge of the box. The German keeper spills it though and has to back-peddle to claw the ball away from dropping into the corner.
Chelsea 1-0 Arsenal
As things stand, Chelsea are going five points clear at the top of the WSL.
If Chelsea win and Manchester United fail to beat Manchester City later than they are champions.

What a goal!
Not sure if you could see on the TV but Eve Perisset actually slips as she pinged that ball across to Guro Reiten.
It's a sublime finish from Reiten too as she used the pace of the ball to guide it into the far corner on the half-volley.
That's lifted the crowd again.
Chelsea 1-0 Arsenal
Also, a word on Eve Perisset whose cross for that goal was sublime. Inch-perfect.
Everton v Brighton (13:00 BST)
Kick off in this one from Walton Hall Park is just five minutes away.
Everton are looking to keep their faint hopes of closing the gap on fifth-placed Aston Villa alive. Currently, it stands at six points with Villa kicking off at home to Liverpool a little later on.
Brighton, meanwhile, can climb to eighth, at least temporarily, with a win after Tottenham beat a struggling Reading on Saturday.

She's had a really good season.
A cute left foot finish [for the goal]. She's been the top assister for Chelsea and in the league, and it's just been a brilliant season for her.
A very talented player.
Chelsea 1-0 Arsenal
Goal number 12 of the season for winger, midfielder and occasional wing-back Guro Reiten.

Great goal. It was coming wasn't it?
Great ball in behind from Perisset, and that is a great finish from Guro Reiten, first time into the back of the net.
A deserved lead for Chelsea, but work to do for Arsenal.
Guro Reiten
A huge step towards the WSL title!
Chelsea have a free-kick and eventually shift the ball out to Eve Perisset who fires in a delightful cross to the back post.
There's nobody picking up Guro Reiten who scores a fantastic goal, getting to the ball on the slide and guiding it into the net.
Chelsea 0-0 Arsenal
Arsenal build a rare attack after great hold-up play from Stina Blackstenius.
She tries a one-two with Kathrine Kuhl but it doesn't come off and Chelsea win it back.
Chelsea 0-0 Arsenal
Hope Powell's right - when's she not?
Chelsea are trying to score the perfect goal. One pass too many.

Chelsea know that three points is imperative for them today, for Arsenal too for the Champions League.
Chelsea are on the front foot and in command of this game at the moment, but still they are without that all important goal. Chelsea need to be taking their chances earlier, shoot instead of taking that extra touch.
Chelsea 0-0 Arsenal
We've only had 17 minutes but it feels like we've had a whole half of action.
Chelsea's Lauren James feeds in Sam Kerr but her cross/shot is easily dealt with by Arsenal stopper Manuela Zinsberger.
Chelsea 0-0 Arsenal
If Chelsea only draw today they'll be three points clear of Manchester United who play rivals Manchester City tonight.
Chelsea's goal difference is four goals stronger.

Caitlin Foord does really well, great through ball. And you've got to say Blackstenius should score.
A strong save from Berger, spread herself really, really well. A good goalscoring opportunity for Arsenal.
That's what they can do, they haven't had much play higher up the pitch. But they have had some good opportunities, you just have to take them.
Chelsea 0-0 Arsenal

Stina Blackstenius has looked really sharp. Arsenal are attacking at the goal near their supporters and they are getting really excited whenever she picks it up. That was just a touch too many to allow Ann-Katrin Berger to race off her line and make the block.
Chelsea 0-0 Arsenal
A huge save!
Caitlin Foord plays a delightful ball through to Arsenal striker Stina Blackstenius but keeper Ann-Katrin Berger does brilliantly to race off her line and close down the angle, keeping out the forward's shot with a brilliant one-on-one save.
A massive moment in the title race.
Chelsea 0-0 Arsenal
Arsenal have been caught out in position so often and we've barely gone past the 12-minute mark.
They're living dangerously.
