Arsenal are not willing to settle for a one-goal lead.

Brighton, who did so well to contain the league leaders in the first half, are being run ragged.

Beth Mead is the latest to cause panic. She has a shot blocked.

Vivianne Miedema finds Kim Little with a long ball down the left. Megan Walsh comes off her line to try cut out the danger, but has second thoughts.

The ball eventually falls to Tobin Heath, who tries to create room to shoot in the box. Instead she plays it to Jordan Nobbs, who hammers a shot wide.

Brighton boss Hope Powell makes a double change.

Danielle Carter and Julia Zigiotti Olme make way for Kayleigh Green and Emily Simpkins.

Much better from Arsenal now, they're finding each other in pockets of space. When Brighton do get the ball they are quick to press them like we saw in the opening stages of the game.

Arsenal are looking much sharper. They're creating a lot of chances in this second half.

Brighton are chasing the game and certainly not out of it. Danielle Carter has an effort blocked.

Two fantastic finishes there from Arsenal, really changed in this second half - different performance from the first. Goals looked like they were coming and two have come at once.

Victoria Williams goes into the book now for Brighton.

Tobin Heath slid the ball in behind the defence and Beth Mead was after it in a flash. But the forward is clipped by Victoria Williams before she could get to it.

Mead is back on her feet and looks keen to take the free-kick from the top of the box.

Arsenal go looking for a quick second.

Beth Mead searches out Tobin Heath, but the American is caught offside.

Maya Le Tissier clatters Beth Mead on the edge of the area.

Arsenal have a free-kick in a very dangerous position on the left.

Like the early minutes of the first half, this is all Arsenal again.

The hosts earn a corner and eventually Tobin Heath has a crack. But yet again the shot is gripped by Megan Walsh.

Vivianne Miedema looks to have made it a personal mission to pull a goal back for Arsenal.

That was exactly what we expected to see from Arsenal in this second half, going at it straight away to get that equaliser and cement their place at the top of the table. They don't want to let Chelsea get back in it.

That move looked so dangerous from Arsenal, the perfect pass to Miedema. You would usually expect Miedema to bury a chance like that.

Megan Walsh is again called into action.

Leah Williamson sends a wonderful long diagonal ball across to the left for Jordan Nobbs.

The Arsenal midfield has Vivianne Miedema running inside her, but she goes for goal herself. Walsh makes a routine save.

Arsenal first attack of the second half sees Beth Mead thread the ball through for Vivianne Miedema.

The Dutch striker has Brighton's defence backtracking, and she tries to beat Megan Walsh from the edge of the area. It takes a deflection and is easily caught.

Before Tobin Heath snatch a dramatic late equaliser against Manchester City at the weekend, the Gunners were set for a sixth defeat in seven matches in all competitions.

Will Brighton actually make that a sixth defeat in eight games? They have 45 minutes to turn it around.

We are back up and running at Meadow Park.
