The Gunners are doing their bit, but they need two others results to go their way - and they aren't.

Chelsea almost double their lead, but Fran Kirby is denied at close range by a good save from Ann-Katrin Berger.

Kirby's pace is a nuisance for any side.

With the top three all winning, it's 'as they were' at the top for now, except that fourth-placed Liverpool have slipped further adrift.

Chelsea remain top, above Man City on goal difference, while Arsenal are one point behind them both in third.

"That was a proper poacher's goal - Jill Scott was standing almost on the line and there were a couple of glances to the officials. It's great reactions from Jill Scott though."

Meanwhile, mid-table Reading lead at Sunderland, as Melissa Fletcher heads in the opener.

It's been a game with plenty of chances so far in the north east.

That goal lifts Reading up to fifth in the table - above Sunderland - as it stands.

Liverpool look to respond quickly, but Gemma Bonner fires wide at the near post from a low corner.

That Chelsea goal is bad news for these two sides, who need Chelsea to slip up to give themselves hope of winning the title today.

Fran Kirby is clattered in the box by Birmingham keeper Ann-Katrin Berger, who is booked.

It's a clear penalty.

Birmingham are set up nicely to try and break on the counter this afternoon, sitting fairly deep against Chelsea.

The hosts have got players behind the ball, ready to try and release Rachel Williams up front when they can.

The former Notts County striker is working hard chasing down everything.

Manchester City continue to search for the opening goal in Widnes, as Toni Duggan runs the ball towards the penalty area, but she slightly overhits a through ball and it rolls harmlessly out of play.

We're still waiting for the first really big chance in the three title-deciding games.

It remains goalless at Stoke Gifford Stadium too, where third-placed Arsenal face Bristol City.

Chelsea were impressive 4-0 winners in Bristol on Wednesday night.

Arsenal's Jordan Nobbs tries her luck from range, but shoots over the bar.

Manchester City break forward quickly down their right through England midfielder Jill Scott, who causes problems in the middle with a fine cross, but City can't get a shot away and eventually play halts as Liverpool's Gemma Bonner has a knock.

It's been a relatively quiet start for Chelsea, who will be champions today if they win.

Both sides have seen early corners eventually come to nothing.

Rachel: My player has got to be Deanna Cooper she has made a fantastic step up from WSL2 and Solid at back for Chelsea.

I'm asking who your player of the season is - get in touch via #bbcfootball

Does anyone agree with Rachel?

Remember, Birmingham knocked out Chelsea on penalties on the Women's FA Cup semi-finals.

History suggests this won't be an easy game for the leaders, despite the fact they have scored 11 goals in their past two games.

Hosts Birmingham get the game under way at Solihull Moors FC, with leaders Chelsea in their white away kit.
