The visitors' defender Alanna Kennedy is booked.

Spurs midfielder Chloe Peplow can't continue. She's clutching her ankle. Josie Green comes on instead.

We've got 20 minutes of the 90 to go. Extra time awaits, unless someone can find a winner beforehand.

Spurs midfielder Chloe Peplow has picked up a knock to her ankle but is persevering for the time being.

On the bench, I don't think we've seen Alex Morgan sent to warm up just yet. She hasn't played of course for a year, having given birth to her daughter on 7 May.

In case you're wondering, the winner of this finely-balanced tie will face either Leicester City or holders Manchester City in the last four on Thursday.

That semi-final will be live on BBC Two - just like this game is.

It was always going away from goal, but what a strike that was!

The Gunners' Katie McCabe swerves a free-kick just wide of the far post. Arsenal are getting closer.

You wonder how long it might be now before Spurs bring on new signing Alex Morgan, assuming they feel she is fit enough, after such a long period without a competitive game. The game is there for the taking.

Arsenal have England's Beth Mead on the bench. Not a bad option either!

The Gunners' Vivianne Miedema finds room to shoot from outside the area but her rising effort flies over the bar.

At the other end, Spurs' Alanna Kennedy has a free header from a corner but nods just wide of the target. Big chance.

Arsenal have the ball in the net through Katie McCabe but the whistle had just gone for a foul in the area against the Gunners. Still 0-0.

It's been all Arsenal since the restart.

A slick Arsenal move presents England midfielder Jordan Nobbs with a chance to shoot from inside the box, on the right, but it's straight at Spurs keeper Becky Spencer from a fairly tight angle.

I think Joe Montemurro will be pleased with Arsenal's effort and enthusiasm in the first half but I don't think they have found their rhythm and fluidity like they have shown in previous games.

They like to dominate the ball and they haven't done that in this game.

Scotland's Kim Little goes short from the corner this time and the Gunners work the ball across to the opposite flank, but Spurs defend the second phase really well and the ball is cleared.

Arsenal force the first corner of the second half and - after a deep delivery from Kim Little - they win another.

Spurs, in their traditional white shirts, dark blue shorts and white socks, get the game going again.

The players are back out for the second half in Hertfordshire, where the rain continues to come down.

Beating league champions Chelsea in Sunday's quarter-final could be a "huge springboard" for Everton, says Toffees boss Willie Kirk.

"I want to win silverware and be challenging for silverware," Kirk told BBC Sport.

"More importantly, for the club it's more steps in the right direction in terms of to getting us back towards where we were a number of years ago, which was consistently challenging for trophies.

Former Leicester City striker Emile Heskey says he did not hesitate to accept a return to the club in a role working with the Foxes' women's side.

The 42-year-old ex-England front man has started an ambassadorial, coaching and mentoring role with the second-tier team, who recently turned professional.

The lowest-ranked side left in the cup, Leicester host the holders Manchester City in the quarter-finals tomorrow [14:00 BST].
