That double change now takes place with Macario replacing Johanna Rytting Kaneryd and Lawrence replacing Wieke Kaptein.

Chelsea are preparing another double change with Catarina Macario and Ashley Lawrence going through their final preparations on the touchline.

On the pitch another busy run from Mayra Ramirez down the right ends in another good stop from Melina Loeck.

Lauren James is a whisker away from her second and Chelsea's third of the game.

She arcs a free kick over the tall Brighton wall but it is always curling away and drops inches wide of the upright.

Chelsea are definitely building pressure now but Brighton are defending well.

Fran Kirby has just gone down holding the back of her leg so hopefully that's not another injury.

Johanna Rytting Kaneryd cuts inside from the right before stinging the palms of Melina Loeck with a low drive.

Chelsea are getting closer to that third goal.

Appeals from the away fans as Rachel McLauchlan falls on the ball in her own box after trying and failing to tackle Sandy Baltimore.

The referee waves away the appeals though having already called for an offside.

Brighton may well consider themselves lucky with that one as it did look like it hit the defender's hand.

Chelsea are upping the ante now as they look to re-take the lead in this one.

Brighton, having done well to take the game to Sonia Bompastor's side and come from behind to lead, will need to keep pushing if they are to hold onto a share of the spoils here.

Disappointment for Seagulls skipper Vicky Losada who is forced off with an injury.

Dejana Stefanovic comes on to take her place in midfield.

Replays showed that Lauren James was standing in an offside position as Mayra Ramirez ran through and shot at goal in the run up to the equaliser.

Chelsea won't care though, their unbeaten record for the season is back in tact for now.

Mayra Ramirez had an instant impact in the build-up to that goal.

She must be one of the best players you can have coming off the bench in the WSL.

That's that for the world record signing on her debut.

Nathalie Bjorn has been getting ready for a few minutes and comes on to take her place at centre half.

Mayra Ramirez also comes on, replacing Sjoeke Nusken as the visitors go for a tactical re-shuffle.

Naomi Girma called over to Sonia Bompastor and pointed towards her left foot. She then shouted for support from Millie Bright, who told her to go down so they could stop play. There's activity on the Chelsea bench.

Debutant Naomi Girma has sat down on the turf and signalled to the Chelsea medics.

She looks to be struggling with something.

It's been a bit of a baptism of fire for world record signing Naomi Girma so far in the Chelsea back line against a rampant Brighton but that goal saving challenge will give her a big boost.

Fran Kirby runs around the outside before getting to the byline and shooting from the tightest of angles.

Hannah Hampton denies her but the parry rolls loose in the box and she requires a crunching tackle from Naomi Girma on Vicky Losada to bail her out.

Madison Hayley does Naomi Girma for pace down the right flank before picking out Fran Kirby in the box.

She lays the ball off to Nikita Parris to shoot but it rolls well wide of the post.
