While we take a breather before extra time, let's see the team news from the other semi-final at Leigh Sports Village...

Annnnd breathe!

What an exhilarating end to that second half. Jess Naz stepping up late on to make sure Spurs take this tie to extra time.

The home side looked to have the better of the closing minutes and the visitors had Lize Kop to thank for keeping them in it in the end.

Tough to call which way this tie goes now.

A Spurs fan in front of us has a little girl with her and she's watching cartoons on a phone screen.

As someone to my left just said, 'how can you watch cartoons with this drama going on?!'

We head to extra time in north London.

Booking for CJ Bott, who takes out a Tottenham forward as the home side looked to counter attack.

Definition of taking one for the team there.

That is an unbelievable save from Lize Kop. I thought it had hit the post! Great reactions. The momentum is definitely with Tottenham.

Wow! Even I had my hand over my mouth!

Lize Kop celebrates that like she has just scored a goal. It's a huge save! She get's an important touch on that.

Bold, confident goalkeeping from Lize Kop.

She rushes off her line to claim a through ball, denying goalscorer Jess Naz the chance to grab her second of the game.

Tottenham look the more likely to nick this, with Beth England also inches away from becoming the hero.

She arrives at the back post but can only side foot the ball wide of the target.

What a save! Bravo Lize Kop!

A ball is floated into the box towards Martha Thomas who takes the ball down with a wonderful touch and toe pokes towards goal.

The Leicester keeper starfishes to block the shot, getting a finger tip on the ball to push inches wide.

We head into six minutes of stoppage time.

Plenty of time for one final twist in this game.

A cross is swung into the box from the left hand side, searching for the heads of Bethany England and Martha Thomas in the middle.

Thomas rises to meet the ball but her header drops wide of the net.

Into the final minute of the 90 and this game is anyone's for the taking.

Back to end to end action that we saw in the opening stages, and both sides look like they have their eye on a winner.

What an effort.

Shannon O'Brien dribbles into the Spurs box, sits down two defenders and chops a powerful finish towards the near post.

Becky Spencer is wise to it though and parries the ball wide and away from danger.

The momentum has switched fully in the home side's favour now.

A ball into the box from the left hand side looks to be on a plate for Bethany England in the middle, but the ball drifts agonisingly past the striker's outstretched leg.

The NOISE in here. Wow. It always felt like Tottenham could find an equaliser and that was worth the wait for their fans.

Tottenham assistant manager Vicky Jepson was immediately stood on the edge of the dugout pointing to her head and telling the players to focus.

They have worked so hard to get back into the game.

Jessica Naz does really well because she does not give up on it.

She doesn't stop, she keeps on it. Josie Green mis times it completely.

Calm and composed finish into the bottom corner. Great finish.

Well who saw that coming?

Tottenham had been wasteful all afternoon long, but Jess Naz finally found that cutting edge and composure they had been looking for.

Ten minutes to go, can either side find a winner?
