Caroline Weir's shot is blocked behind by Louise Quinn and City have a corner.
One final opportunity?...
Arsenal 0-0 Man City
There'll be three minutes added on at the end of the half - presumably for Caroline Weir's earlier injury.

It's a bit flat, with neither team offering much up front so far, happy to be patient and try to work the triangles near the halfway line.
Someone's going to have to change something at half-time, or else we might as well prepare for penalties.
Arsenal 0-0 Man City
We're marching towards half-time at Bramall Lane - can either team muster a shot on target before the break?
Arsenal 0-0 Man City
That's a bit of a silly one.
The first yellow card of the League Cup final goes the way of Manchester City's Georgia Stanway, who kicked the ball away after conceding a free-kick.
Arsenal 0-0 Man City
Caroline Weir is indeed back and seems to be moving a bit more freely now.
Arsenal win a free-kick on halfway - Lucy Oliver, wife of Premier League referee Michael Oliver, is the woman in black today - and will attempt to build another attack.
Arsenal 0-0 Man City
She gingerly climbs back to her feet and wanders to the touchline. She doesn't look happy, but I reckon she'll at least try to continue.
All the while, City clear the corner.
Arsenal 0-0 Man City
The last few minutes have been played almost exclusively in the Arsenal half - but their defence is afforded a wee breather as they break and win a corner off Caroline Weir.
The Scotland international has actually stayed down and is holding her knee. There are a few concerned faces on the Manchester City bench...
Arsenal 0-0 Man City
Just like Beth Mead for Arsenal, Nikita Parris is such a key player for Manchester City.
The Women's Super League's all-time top goalscorer - at the age of just 24, by the way(!) - nearly gets through down the left but she's superbly shepherded away from danger by her England team-mate Leah Williamson.

All the players on the far side - Man City's left flank and Arsenal's right - appear to be having some difficulty with the bright Sheffield sunshine.
They're all shielding their eyes at every opportunity and it may be a factor with diagonal balls.
Arsenal 0-0 Man City
We're still yet to have a shot on target at Bramall Lane.
Can the Gunners get striker Beth Mead into the match a bit more? They'll be hoping so.
Arsenal 0-0 Man City
Arsenal again attempt to play out from the back but this time fall foul of very thing I suggested a few moments ago - a stray pass in a dangerous area.
Manchester City are quick to pounce and swiftly work it to Nikita Parris, whose first touch is brilliant but she can only fire it over the bar.
Arsenal 0-0 Man City
That's more like it!
Arsenal inject a bit more pace and purpose into their play, releasing the impressive Danielle van de Donk down the right.
Her cross is a dangerous one but Steph Houghton just about manages to put it beyond at the near post - albeit nearly squeezing it into her own net in the process.
Arsenal 0-0 Man City
The game is now starting to settle down into a slightly more familiar pattern, with both teams patiently keeping the ball and enjoying spells of possession.
It almost feels as though the most likely route to a goal would be a misplaced pass out from the back.
Arsenal 0-0 Man City
Phil Neville is at Bramall Lane to watch several of his England internationals in action in today's Women's League Cup final.
The England squad will soon be heading to the USA for the SheBelieves Cup, with their first match against Brazil taking place on Wednesday.
Arsenal 0-0 Man City
Arsenal come forward again, however, and force their first corner of the match.
Manchester City deal with the ball in pretty well and Jill Scott makes a really fine tackle to set up a potential counter-attacking opportunity, but it fizzles out when Nikita Parris commits a foul.
Arsenal 0-0 Man City
The first chance of the final goes the way of Arsenal's Katie McCabe - and it's a pretty good one that she doesn't really make the most of.
Kim Little's superb pass picks out Katrine Veje down the left and her cross is only half-cleared by the City defence.
McCabe's first touch is good but, having settled herself, her second really isn't. She blazes it over the bar.

The vast majority of the supporters in here are in one stand, opposite the technical areas.
The noisiest groups of fans from each side have gathered near opposing corner flags, with a couple of hundred Man City fans - all wearing sky blue - bunched together, fighting to make themselves heard over a slightly smaller band of Arsenal fans, who all have clapperboards.
Arsenal 0-0 Man City
England captain Steph Houghton is among those to trudge forward into the Gunners box, but the set-piece is comfortably cleared.
Manchester City have certainly settled the better, though.
Arsenal 0-0 Man City
Half the pitch at Bramall Lane is bathed in beautiful South Yorkshire sunshine and the other is completely shaded over. Always a nightmare for the person operating the camera, I'm told.
As for the actual action, Caroline Weir's cross is blocked by Scotland team-mate Kim Little and City have the final's first corner.
