That injury delay has allowed Willie Kirk's side to gather themselves after Manchester United came swarming all over them in response to Everton's early goal.

It's a good spell of pressure from the visitors but no clear-cut chance is created, as they're limited to a couple of potshots from distance.

Great contest now.

City growing into this one now as we approach 20 minutes in.

They've forced a couple of corners and are finding more of the ball out wide, but no way through as yet.

First real venture for City into Chelsea's penalty box and it's almost an opening goal for the visitors from Lauren Hemp.

A half-cleared corner by the hosts and the 18-year-old almost finds the far corner on the turn with her left foot but it heads wide of the post.

Play is just back under way now after a stoppage of about two or three minutes following a head injury for United midfielder Jackie Groenen, who is okay to continue.

We all needed that little break.

Ji So-Yun again at the heart of Chelsea's early endeavours coming forward.

Unleashes a very good-looking strike from about 25 yards out that is travelling, but is right at City goalkeeper Ellie Roebuck who holds on with both hands above her head.

Nice build-up play once again from Chelsea around the City box, but Ji So-Yun can't quite direct her half-volley on target.

Some promising stuff from Emma Hayes' side both on and off the ball so far in the first 10 minutes.

Man Utd forward Lauren James goes on a mazy run and Megan Finnigan is bamboozled. She hopefully sticks out a leg, and James gleefully falls over it.

Penalty to United and this match is just 100mph.

I was in the midst of writing this before Lauren James hit that quickfire equaliser and scuppered my best laid plans.

Really sorry Mary Earps, but pretty much everyone other than the stadium announcer is saying you punched that ball straight in for the opening goal.

Sorry Simone Magill as well, I guess. No goal bonus for you now.

Cagey start for City who haven't had too much joy getting out of their own half so far in the opening stages.

Chelsea definitely pressing well off the ball. Steph Houghton may have a tricky afternoon up against the pace of Ramona Bachmann on Chelsea's left.

Chelsea making the brighter start in this one and Erin Cuthbert sees a shot from outside the box deflected behind for their first corner.

The hosts fail to make the most of it on what is looking like a very windy south west London.

Plenty to get talking about in the world of football this afternoon and if you've got thoughts you'd like to share, feel free on social media.

Tweet using #bbcfootball and we'll post them throughout the afternoon.

Would a win for either Chelsea or Manchester City in our early game effectively knock the other out of title contention or is that too early to write anyone off?

And we're off and running in the first two games of the day at both Kingsmeadow and Leigh Sports Village.

Don't forget you can listen to live BBC local radio commentary of both matches by clicking or tapping on the listen live option at the top of the page.

These two title rivals played out two draws in the league last season, opening their campaigns with a goalless curtain raiser at Kingsmeadow in September 2018 before South Korea star Ji So-yun’s late strike saw Chelsea come from 2-0 down to draw 2-2 in Manchester.

There was further drama when the two sides met in the semi-finals of both domestic cup competitions last term.

First, City were 2-0 winners at Kingsmeadow in the League Cup, with Nikita Parris scoring twice, before Magdalena Eriksson’s bizarre, stoppage-time own goal settled an FA Cup semi-final in City’s favour and Nick Cushing’s team went on to lift both cups.

Manchester City have conceded just once in the WSL this term, keeping seven league clean sheets in their eight games.

Chelsea remain unbeaten this term and are on a nine-game winning run in all competitions, scoring 11 times in their past two matches.

Man City have won five in a row since suffering three straight defeats in October, when they lost 1-0 at WSL holders Arsenal before exiting the Champions League at the hands of Atletico Madrid.

Manchester United head coach Casey Stoney has said she wants a reaction after their surprise 3-2 defeat by West Ham, and makes two changes - Kirsty Hanson and Jane Ross are replaced by Jess Sigsworth and Lauren James.

Everton should be pretty fresh this afternoon after their match with Chelsea last weekend was postponed because of a frozen pitch.

Their one change from the 3-1 win over Tottenham a fortnight ago sees Kika van Es replaced by Megan Finnigan.
