Leicester had about three chances to clear, when you are champions you only need one moment to change a game. Josie Green was on the line and slightly out of position to clear.

Chelsea lead!
That is so unfortunate for Leicester. Nathalie Bjorn hooks the ball towards the goal, it looks like it's going to be cleared off the line by Josie Green, but Green gets her timing wrong and it sails over her head.
It felt like a goal was coming.

The start to his game from Chelsea was lightning, I thought it would be goal after goal after goal, but they quickly decreased their tempo.
Leicester 0-0 Chelsea
It's been a few minutes since either team had a clear-cut chance.
Leicester will be happy with how they're holding their own.
Leicester 0-0 Chelsea
Mayra Ramirez will be annoyed about that.
Leicester goalkeeper Lize Kop takes a heavy touch, Ramirez goes shoulder-to-shoulder to try and get the ball, but the referee says that she fouled Kop and the hosts are given a free-kick.
Leicester 0-0 Chelsea
Mayra Ramirez falls to the ground after being caught by Courtney Nevin's trailing arm.
A free-kick is given but Nevin isn't penalised.

At the minute, all the fouls have been from Chelsea and not Leicester, compared to what we expected. Chelsea aren't getting anywhere near Leicester at the moment.
Leicester 0-0 Chelsea
It's been a very even game so far - but Leicester have actually had the better of the stats.
Four shots for both sides, but three on target for the Foxes and just one for Leicester.
Leicester have also had 54.3% possession and a better passing accuracy.

When you look at Chelsea, Jess Carter has got a lack of options to pass to and you can see Emma Hayes is getting very frustrated.
Leicester 0-0 Chelsea
Courtney Nevin sends a cross towards the Chelsea box and it ends up being dangerous for Hannah Hampton, curling towards the top corner.
She watches the ball well and catches.
Leicester 0-0 Chelsea

You would expect the target to be hit there, but yes it's a good save from Hannah Hampton.
Leicester 0-0 Chelsea
Argh!
So close for Leicester. Jutta Rantala breaks free out wide and beats Niamh Charles.
Her shot is saved by Hannah Hampton, but it falls to Yuko Momiki.
She fails to hit the target but it's parried behind for a corner by Hampton.
Leicester 0-0 Chelsea
Leicester are producing some excellent defending to keep it level.
Niamh Charles is in down the left-hand side for Chelsea but CJ Bott tracks her run to perfection before snatching the ball from her feet.

Both teams have settled down and if anything Leicester have gone up a couple of gears. Chelsea have almost fallen asleep a little bit, they could do with waking up.
Leicester 0-0 Chelsea
Leicester are in the middle of a period of momentum and putting Chelsea under a lot of pressure around their box.
They earn a corner after Eve Perisset is forced to head behind an Aileen Whelan delivery.
