Interesting first sub from United - Rachel Williams replaces Nikita Parris, who had been looking dangerous today.

Williams, who scored United's winner in the semi-final against Brighton, will play centrally with Alessia Russo out wide.

Oof, Pernille Harder is already down just after coming on. She was trying to press Millie Turner, who held her ground and the forward ran into her.

Nothing wrong from Turner, and Harder will be fine.

Immediate chance for Pernille Harder!

Maya Le Tissier fails to deal with a long ball, Sam Kerr races on to it down the left wing.

Her low cross finds Harder, however her first touch sees the ball trapped under her foot, and she can't get enough power or placement on the shot to beat Mary Earps.

It's a brilliant ball from Nikita Parris. She sees Alessio Russo drifting in at the far post but it's just ended up a little bit too deep.

The game has spiced up over the last five minutes.

Emma Hayes has seen enough, she makes a double change.

Pernille Harder comes on for Jessie Fleming, the Canadian forward has offered little today. Harder could be a very different proposition.

Also, Sophie Ingle replaces Melanie Leupolz in the centre of midfield.

Nikita Parris clips a great cross from the right wing, with Eve Perisset doing really well to head away from the waiting Alessia Russo.

Niamh Charles then gets a booking for an earlier foul.

Quick-thinking long pass from Maya Le Tissier sets Leah Galton away, however her right footed shot lacks power and Berger saves.

There is a really good tempo to this game now. United continue to have the upper hand.

Ella Toone looks to have broken the offside trap, she streaks onto a through ball but the cutback to Alessia Russo is intercepted.

Then the offside flag finally goes up. I know it has to be delayed for VAR purposes, but come on.

Erin Cuthbert has a dodgy moment, as she fails to deal with a pass from the left and loses possession to Alessia Russo.

Russo takes an early shot from distance, which is easy for Ann-Katrin Berger. Let off for Chelsea.

England manager Sarina Wiegman is spotted in the crowd by the TV cameras.

Just over two months now until the 2023 World Cup. I can't wait.

The first sign of danger for United, Lauren James is almost played clean through in the area.

Millie Turner with some good defending to intercept just in time.

I think Pernille Harder will come on sooner rather than later. She has played well recently after her comeback and scored goals, albeit against teams she should be scoring against.

Doing that against Manchester United will be much more difficult.

It's interesting that some of the key players on show today could be playing their final few games for their clubs.

Ona Batlle and Alessia Russo are out of contract at United this summer, while Chelsea's Magda Eriksson and Pernille Harder are being linked with Bayern Munich.

If they do depart, they will want to sign out with a winner's medal.

Second half, underway.

Some mixed reaction to the decision not to award Manchester United a penalty at the end of the first half.

Ronarid 9: Foul continues into the area - joke decision.

Wendy Temple Author: The VAR referee took all of 5 seconds to make that decision. Not enough time to consider whether the foul continued into the box.

Emma Harvey: Penalty all day long!

Scott Gregory: Looked a penalty to me.. Close though. VAR clearly thought differently..

The players are heading back out onto the field now, the second half is imminent.

Will we see a winner? Or are we destined for extra time, and possibly penalties?

Nikita Parris is playing with attitude and that's when you get the best out of her.

When she left Arsenal and joined United she probably wasn't performing at her best, she had to work her way into the team and she wasn't selected by England.

That hurt Nikita. She's shown up well today and is putting herself in a postion for Sarina Wiegman to pick her in the summer.

United have been on the front foot and pressing Chelsea back in the wide areas.

They've put plenty of crosses in and that approach is working for them.

Chelsea's only shot on target in the first half came when Lauren James looped a header towards goal.

It required a brilliant save from the Manchester United and England number one.
