What a ball that was from Jelena Cankovic. She threads it through Arsenal's midfield, up to Carla Carnacho whose first touch lets her down on the edge of the box.

Just as they did against Villa in the WSL and Lyon in the Champions League, Arsenal have led after a sharp opening - then immediately allowed their opponents back into the game.

Renee Slegers must be tearing her hair out.

Kiko Seike throws herself at the ball to try and nudge the cross towards goal, but she takes out both Katie McCabe and Daphne van Domselaar in doing so and the referee blows for a foul.

Brighton are looking dangerous.

Arsenal have taken their foot off the gas after that opener and it's allowing Brighton to settle into the game.

Fran Kirby comes close to levelling with a looping chip, but Arsenal manage to clear before the ball crosses the line.

Renee Slegers has liked to rotate her number 10 this season and today it is nominally Mariona Caldentey in that position.

However it is a more flowing situation, with Caldentey, Olivia Smith, Caitlin Foord and Frida Maanum all getting into attacking midfield positions.

Brighton have not been able to cope with the numbers and quality, and the goal was inevitable.

That goal has gone down as a Marisa Olislagers own goal.

It's funny because over the last few games I thought about Smith and if she's been making the right decisions and there, she's actually looking to put the ball across the box but it takes a big deflection to go in the goal.

We know she can be prolific though and sometimes you just need the rub of the green.

Olivia Smith steals the ball off a Brighton defender and Alessia Russo has to quickly move out of the way before the Canadian smashes her shot into the side-netting.

Chiamaka Nnadozie has made three saves already today, taking her up to 25 in the WSL this season.

The Nigerian international will likely have to add a fair few to that tally if Brighton are to get anything from this game.

Good keeping from Chiamaka Nnadozie, who leaps on the ball before Caitlin Foord can get a close-range strike away.

Really good adjustment from Nnadozie, adjusts her feet and gets a great hand to it. Foord with the follow up and safe hands for a corner.

Katie McCabe has scored from there before and she almost does it again. Chiamaka Nnadozie is waiting for the cross, but the delivery from McCabe is heading straight in and the keeper has to quickly retreat.

Katie McCabe lays the ball off to the overlapping Caitlin Foord, whose cross is deflected out for a corner.

Foord flicks on the in-swinging delivery and the ball trickles out to Smith on the edge of the box, but the summer signing sweeps a ferocious strike over the crossbar.

What I find with Arsenal sometimes is they have all of this possession, but it's so slow. I don't know how you're expecting to move a team when it's done at such a slow pace.

Of course you're comfortable in possession but you need to move it quickly - one, two touch and in and out.

Mariona Caldentey whips in a deep cross, but there's too much on it and it whizzes over the head of Oliva Smith.

Good organisation from Brighton.

Katie McCabe and Mariona Caldentey play a couple of passes between each other on the right wing, but they can see no way through and the Seagulls force them back.

Arsenal know their qualities and they haven't been getting the results they know they should be getting. They don't want the league title slipping away from them so these games especially are so important for Arsenal.
