Chelsea, who are without long-term absentees Karen Carney and Anita Asante through injury, start veteran midfielder Katie Chapman in the holding role, in what is her 11th FA Cup final appearance.

Arsenal opt for the Netherlands’ Vivianne Miedema and Beth Mead going forward, with Danielle Carter and Heather O’Reilly on the bench instead.

On a bank holiday weekend, with the sun shining amid a clear blue sky, and a new competition-record expected at the home of football, does it get any better than this?

With two of the country’s best teams going head-to-head, there are hopes here that this game could go down in history as one of the Women’s FA Cup’s best finals.

‘Wembley Way’ is heaving, a sea of red and blue, as it has been for so many previous big games.

And - as both managers have stressed this week - make no mistake about it, this is a very big game.

Speaking of her opposite number, Arsenal boss Joe Montemurro, Chelsea manager Emma Hayes told BBC Sport:

“Great guy. Made a great start. Brought the stability that probably the team was looking for at that time.

“Arsenal have been a yo-yo side in the past couple of years, cups, underachieving in the league. It’s still the case, so he’s got some work to do, but he’s certainly making the right noises.

“As are the players - he’s hugely respected by them – but it takes time, to reach the levels where you find consistent performances.

“He’s an Arsenal fan as well so for him I think there’ll be a lot of pride at the weekend.”

Arsenal's manager Joe Montemurro has only been in English football since November.

The Australian says taking over as Gunners boss has been "surreal".

We told you Tom Garry had been busy. Have a read of his fine article to find out what leading a team out at the home of football means to Montemurro.

Chelsea have had a great season. They are second in the league, behind Manchester City on goal difference, and made the semi-finals of the Champions league for the first time in their history.

An FA Cup win today would be their second success in the competition following their triumph in 2015.

Emma Hayes' side lost to 14-time winners Arsenal - yes 14 - when the two sides met in the final in 2016.

The Gunners are fourth in the league and aiming for a cup double, having won the Continental Tyres Cup in March.

Tom Garry, external, a man who works so hard he needs two Christian names, is our Wembley eyes and ears today.

Have a quick perusal of his preview for more facts and figures.

More than 40,000 tickets have been sold for today's Wembley meeting.

That was already a record and the glorious sunshine could help swell that number even further by the time the action gets under way.

Last year's final, which saw Manchester City outclass Birmingham, set the previous best of 35,271.
