That was a superb ball into the box from Katrina Gorry, right in front of the six-yard box.

There's no West Ham players to get a touch on it, though, and the attack fizzles out.

Better from the Hammers, but not quite good enough.

Tenacious pressing from Katja Snoejis almost pays off big time for Everton.

She dispossesses Guro Bergsvand momentarily on the edge of the Brighton box but is crowded out in the end before she can get a shot away.

A much brighter start to the second half from Everton.

Oh dear. That's an opportunity wasted for West Ham.

Kristie Mewis lofts the ball over the Manchester United defence, finding Katrina Gorry in the middle of the penalty area - only for the new skipper to blaze an effort over the ball.

An Everton corner is cleared by the Brighton defence but it falls kindly for Inma Gabarro to strike from the edge of the box.

The Spaniard unleashes a rasping drive at goal but Sophie Baggaley gets two strong hands behind it to parry the ball out of danger.

Kristie Mewis drills in a corner for West Ham, but Maya Le Tissier is there at the near post to head away and the ball ends up all the way back at West Ham keeper Kinga Szemik.

Tidy play from Fran Kirby as she evades the challenges of several Everton defenders before laying the ball off to a teammate.

She is involved again shortly after, it's a neat give and go with goalscorer Kiko Seike, but her run into the box is halted by Elise Stenevik.

Another change for West Ham and it's another new signing.

Manuela Pavi, who joined from Deportivo Cali, replaces Viviane Asseyi.

It's been a very comfortable afternoon for Phallon Tullis-Joyce in the Manchester United goal. Just the one shot on target from West Ham.

So far, so good as she steps up to replace Mary Earps.

Back under way at Broadfield Stadium.

Speaking to some fans here in Crawley, they like what they have seen from Dario Vidosic’s Brighton so far.

They look more exciting going forward, more direct and more intense in their pressing.

Everton have struggled to get into the game but still look threatening when they play it out wide and get balls into the box.

But so far so good for the new-look Brighton and their big-name signings have made an impression.

That was very nearly a peach of a ball from Ella Toone to release Elisabeth Terland through on goal.

Amber Tysiak gets there just in time to clear the danger.

What a debut so far from Brighton forward Kiko Seike.

Most shots on target, most chances created and most touches in the opposition box of any Brighton player in the first half.

And most importantly a wonderful goal to break the deadlock.

A bit of a coming together between Phallon Tullis-Joyce and Emma Harries knocks the West Ham player flying.

The medics are quick to run on to the pitch and see to Harries, who is able to walk off unharmed a few minutes later.

That's her last bit of action this afternoon as she's replaced by summer signing Seraina Piubel.

Grace Clinton spent last season on loan at Tottenham and her impressive performances there earned her an England call-up.

It looks like she's carrying that same form into this season as she scores on her debut - at Old Trafford, no less!

What were West Ham doing there?

They leave Grace Clinton completely unmarked to meet a Lisa Naalsund delivery and her header goes past Kinga Szemik, with the West Ham keeper staying rooted to her spot.

The hosts have started the second half well and now have another goal. They've been controlling.
