Having just come on full-back Smilla Holmberg jumps at the chance to get forward on the right.

She has plenty of time to assess her options but chooses poorly, firing wildly into the stands behind the Manchester United net instead of picking out a teammate in the middle.

Chelsea replace Sjoeke Nusken with Guro Reiten.

City right-back Kerstin Casparij brings down Sjoeke Nusken after gifting the ball to the Chelsea midfielder, and is rightfully booked.

They're not doing either at the moment, Lee.

A nice team move from City ends with Vivianne Miedema laying the ball off to an onrushing Kerstin Casparij, but the City right-back lashes her strike over the bar.

How many more chances can City afford to waste?

More Arsenal changes as they continue to chase the tie.

Off: Victoria Pelova and Taylor Hinds

Chelsea have decided that attack is the best way to defend their slender lead, and Sandy Baltimore is leading the charge.

She almost squirms between Laura Blindkilde Brown and Vivianne Miedema with an audacious piece of skill, but she just runs out of pitch.

She's such a tricky player to get the ball off.

Melvine Malard has the freedom of the back post to pick her spot but the substitute skews her effort over the crossbar.

Ah that could have been game, set, match for Manchester United.

Mind you the Sweden international was one of five United players that have been booked, so could just be a case of trying to make sure they keep the personnel advantage? Another of those, Sandberg was brought off earlier too.

Chelsea's Sandy Baltimore cuts in from the left and looks to curl one in the far top corner, but Ayaka Yamashita produces a great stop.

Are United going for that killer second goal? Looks like it, as they're bringing on the speedy Melvine Malard in place of midfielder Julia Zigiotti Olme.

It's silly from Olivia Smith.

Is that because over the last five or 10 minutes she's been whacked a bit? Is that a bit of frustration?

She had a booking early on and you've got to be careful. As soon as I saw it was Smith I knew she was gone.

Manchester United are 22 minutes away from their first-ever League Cup final appearance.

That would be a very special way for Marc Skinner to celebrate tonight on his 150th game in charge of the club.

City have had the better chances this half, but Chelsea's attackers are finding pockets of space when they do attack.

It's as if they're sneaking up out of view of the City defenders, just off the shoulder. City need to be careful.

Manchester City are in the winning habit, aren't they?. They need to find a way to get back into this one.

I've been impressed with the way they have an identity under Andree Jeglertz this season.

Hannah Hampton produces a stunning save of her own!

Yui Hasegawa chests a clearance down at the edge of the penalty area before striking on the volley, but Chelsea goalkeeper Hampton does superbly well to tip over the bar.

Arsenal have upped the ante now, unfazed by the player disadvantage.

They pop the ball around the edge of the United box to make space for a shot, which Mariona Caldentey duly fires towards the bottom corner, forcing Phallon Tullis-Joyce down sharply to turn it behind.

Marc Skinner makes his first changes of the evening, looking to keep legs fresh in the Manchester United ranks.

On: Hannah Lundkvist and Lisa Naalsund

It's a wonderful turn and absolute rocket from Lauren James.

She's magic the way she can turn on the ball.

Excellent save.
