Defending champions Manchester City beat Arsenal to reach the final
Everton defeated Birmingham City to secure first final appearance since 2014
Everton 1-1 Manchester City
Alex Greenwood's inswinging delivery is a dangerous one but Sandy MacIver just about gets there.
It's half cleared by Chantelle Boye-Hlorkah before Steph Houghton almost sneaks in behind.

Everton have made a few changes. Poppy Pattinson and Simone Magill are on. Valerie Gauvin and Rikke Sevecke are off.

Manchester City will be kicking themselves that they have not won this and that they have got to go again.

On Everton's equaliser...
It was a classic near-post ball by Izzy Christiansen. We talked about the belief of Valerie Gauvin - it got Everton back into the game.

The story so far.

We're going to extra time in this final for the first time since Birmingham beat Chelsea on penalties at Ashton Gate in 2012 and this is without doubt the best final since then.

One of several BIG chances in the second half. Caroline Weir probably can't believe how she hasn't won it.

Unbelievable movement from Manchester City. You thought Caroline Weir's effort was going to go into the top corner.
It's so difficult to call which way this is going to go.
Everton 1-1 Manchester City
Wow. Breathless stuff. We're heading to extra time!

And now Everton are on the attack. Nicoline Sorensen sprints through the middle and draws a save at the near post by Ellie Roebuck.
The header is wide from Damaris Egurrola from the resulting corner.

Caroline Weir, who has just missed that golden chance, smashes the crossbar with a curling shot from 20 yards out!

Caroline Weir is the player you want in that position. She's normally so clinical. She had so much time and space.

ANOTHER miss from City in the final minutes. Lucy Bronze bundles it out to Sam Mewis on the right initially but her cross comes all the way over to Demi Stokes.
She cuts it back to Caroline Weir, who should score, but she skews it over from an unmarked position, just a few yards out.
Gareth Taylor will be pulling his hair out...

Molly Pike is on for Everton. Off goes Lucy Graham.

You can really sense the urgency from City now. They want to settle this here and now.
Everton are getting ready to make a substitution.

SIX minutes added on. Are we going to extra time? Valerie Gauvin came this close to making it 2-1 to Everton earlier, as another chance for Manchester City goes begging when Sam Mewis' shot on the turn is blocked.

That's a big chance for Manchester City. Lucy Bronze gets away to deliver a cross and Chloe Kelly does well to come in off the line. She does all the hard work but cannot keep it down.
Everton 1-1 Manchester City
Noooooo.
Lucy Bronze does all the hard work, driving along the byline, beating two defenders in the process and lifts it into the middle.
Caroline Weir dives for it and doesn't get there. It falls for Chloe Kelly, who sees it late and she volleys it over from 10 yards out.
