More bad news for Brighton on the substitution front, there.

Sjoeke Nusken scored three against them in October.

Sophie Ingle and Sjoeke Nusken replace Erin Cuthbert and Melanie Leupolz for Chelsea.

Emma Kullberg threads through Lee Geum-min, who cuts the ball back to Elisabeth Terland.

Terland is Brighton's top scorer in the league this season, but she won't want to see that again. Her effort goes high and a long way from Hannah Hampton's goal.

Chance!

Fran Kirby is in space and knocks the ball to Mayra Ramirez, who muscles off her defender with an eye towards goal.

She strikes towards Sophie Baggaley but it's saved by the Brighton goalkeeper.

It's been over half an hour since Brighton last had a shot in this game.

Hannah Hampton mistimes a clearance and Brighton collect, but she need not worry, Brighton lose the ball and Chelsea recover.

Mayra Ramirez looks to have the ball behind the Brighton defence, but the offside flag is up.

A potential let-off for the Seagulls.

Aggie Beever-Jones has the ball and opts to take a crack at goal, but it's blocked and cleared.

She had Mayra Ramirez in space. Would that have been a better option?

Barring an utterly monumental Brighton turnaround, here's how the table is set to look

Chelsea six points ahead, albeit having played a game more.

Here we go then. What will we see from Mayra Ramirez? She's an exciting signing and she's already gone straight into the number nine position, with Fran Kirby dropping deeper.

We won't see a Lauren James hat-trick this evening.

Mayra Ramirez makes her Chelsea debut in her place, with the British record signing coming on alongside Aggie Beever-Jones.

Johanna Rytting Kaneryd also goes off.

Chelsea attack again.

The ball is cut back to Erin Cuthbert by Johanna Rytting Kaneryd, but Cuthbert's shot is too powerful and goes a long way over the crossbar.

Brighton go forward for the first time in a while.

Lee Geum-min leads the counter attack but her pass to Veatriki Sarri is too heavy and the latter can't get a good cross away.

Chelsea are readying Aggie Beever-Jones, who has five goals in the league this season, and club record signing Mayra Ramirez on the bench.

Not the news Brighton will want to hear.

Lauren James slides the ball through to Guro Reiten, she looks to pull it back to James but the offside flag is up.

Chelsea are starting to ramp up the pressure. There's just under half an hour left to play.

Ruthless.

Chelsea 2.0 in this second half. They should have been ahead at the break but have clearly used that to fuel this second half performance.

Lauren James now has 12 goals in 11 matches, level with Khadija Shaw as the league's top scorer.

Lauren James strides forward for Chelsea and tries to find Fran Kirby on her right-hand side, but Brighton manage to intercept.

Chelsea have scored first eight times in the Women's Super League this season.

Oh, and they've also won all eight games in which they did so.

The stats aren't on Brighton's side.

Huge cheers for Katie Robinson's introduction in particular from the Brighton fans. She's barely on the pitch before Emma Kullberg shouts her over for an intense conversation, presumably passing on observations.
