Arsenal 0-0 Man City
This actually looks a bit ominous for Vivianne Miedema, who is still limping. I'm not sure she's going to be able to continue.

This actually looks a bit ominous for Vivianne Miedema, who is still limping. I'm not sure she's going to be able to continue.
Arsenal 0-0 Man City
How different would this final have been had Vivianne Miedema been fit enough to start?
The Arsenal striker, on as a second-half substitute, brilliantly turns her marker inside out but can't quite direct her shot as she'd have hoped.
She stays down both her and Jill Scott will receive some treatment.
Arsenal 0-0 Man City
Immediately Arsenal start on the front foot and win a free-kick around 30 yards from goal, which is subsequently cleared.
Arsenal 0-0 Man City
Right then, let's crack on with extra-time. Arsenal get us under way - will we have a winner in the next half an hour or will we be treated to a penalty shootout?
Stick with us to find out.
FT: Arsenal 0-0 Man City
This is the first time in 15 meetings between the two teams that it's ended 0-0.
See, we told you there'd be goals. Don't ever accuse us of not knowing what we're talking about.

The attendance here at Bramall Lane on this sun-kissed Saturday has been confirmed as 2,424, which is a sizeable increase on last season and that will please organisers to an extent.
However, it's less than half of the 5,000 or so who attended the 2015 final in Rotherham.
Arsenal 0-0 Man City
And that's your lot - the full-time whistle goes.
The League Cup final is heading to extra-time.
Arsenal 0-0 Man City
Why is Janine Beckie shooting here?!
The Manchester City substitute is perfectly positioned to stand up a cross but, from a narrow angle on the left, instead smashes a shot against the underside of the bar.
So close!
Arsenal 0-0 Man City
Vivianne Miedema and Danielle van de Donk exchange passes on the edge of the City box, but Miedema can't quite get her half-volley on target.
We've not been short of chances since half-time.
Arsenal 0-0 Man City
Three minutes of time added on. Three minutes to get your name on the cup.
Arsenal 0-0 Man City
Jill Scott! So nearly!
The Manchester City midfielder sends a 25-yarder towards goal and for a moment it looks to be flying into the corner, but keeper Sari van Veenendaal gets across to palm it away.
Arsenal 0-0 Man City
Vivanne Miedema hasn't been heavily involved since coming for Arsenal but when she has been on the ball her class has shone through.
The Netherlands striker judges her pass to Beth Mead to absolute perfection but, after a brief hesitation, Mead can only shoot straight at the goalkeeper.
Arsenal 0-0 Man City
We're into the final five minutes. Anyone fancy being a cup final hero? Now's your moment...
Arsenal 0-0 Man City
Surely this is only a matter of time for Manchester City?
Caroline Weir gets clear inside the Gunners box and gets a shot towards goal, but keeper Sari van Veenendaal rushes out brilliantly to divert the attempt behind.
Excellent work from the Arsenal number one.
Arsenal 0-0 Man City
Nikita Parris isn't happy about something - and the Manchester City attacker is booked for a bit of back chat to referee Lucy Oliver.
Meanwhile, Steph Houghton latches on to a City corner but drills her half-volley over the bar.

Substitute Janine Beckie scored four goals in a single game earlier in this competition, against Sheffield United, whose home we're at today.
The Canada striker has netted seven times in all for City since her move from American NWSL club Sky Blue last year, but didn't get her first league goal here until Wednesday's win over Everton.
Expect her confidence levels to be high after that.
Arsenal 0-0 Man City
Nikita Parris twists and turns and works herself a little pocket of space on the edge of Arsenal's box, but can only drag wide of the goal.
Manchester City continue to knock on the door.
Arsenal 0-0 Man City
The big question for Arsenal is how on earth they get Vivianne Miedema in the game - because Manchester City are looking the more likely to win this final at the moment.
By the way, if it's goalless after 90 minutes we'll have the usual 30 minutes of extra time and penalties. We could be here for a good while yet.
Arsenal 0-0 Man City
Another Arsenal change to tell you about - Amelia Hazard is on for Katrine Veje, who limps off with what looks like an injury.
Arsenal 0-0 Man City
You attack, we attack.
Nikita Parris has been Manchester City's biggest threat all afternoon and, having already hit the crossbar, is again inches away from making it 1-0.
She wriggles away from her marker in the box and sends a rasping, right-footed strike narrowly over the bar. The goalkeeper was getting nowhere near that.
