Both sides have enjoyed their fair share of success in the world's most famous cup competition and now they face-off in last season's delayed match.
The Gunners have won the prestigious competition 14 times in their illustrious history, equalling the men's record of cup triumphs.
But the north London outfit's last FA Cup success came when Danielle Carter's scored the winning goal against Chelsea in 2016 - with Alex Scott and Kelly Smith still playing for the club.
It was the only trophy that eluded former Gunners' head coach Joe Montemurro during his four-year stint at the club.
Montemurro, 52, guided the club to a Continental League Cup triumph in 2017/18 and a Women's Super League title the following campaign before leaving last summer.
In the blue corner, Chelsea boss Emma Hayes delivered the club's first FA Cup success in 2015, with Ji So-yun notching the only goal of the game against Notts County
Three years later, in 2018, they won the cup for a second time, beating Arsenal 3-1 but they haven't won the competition since with Man City claiming the 2019 and 2020 iterations.
This year's final sees the London rivals go head-to-heard once again in the Wembley showpiece and it will have huge ramifications for the victors.
Early chance for Jonas Eidevall success with Arsenal
The Gunners' Swedish head coach has never visited Wembley in his managerial career.
In fact, the closest he came to the 'Wembley' experience was purchasing tickets for an Adele concert and later realising he couldn't attend.
Just like many foreign managers, the 38-year-old fell in love with the FA Cup at an a young age, with the matches beamed to his homeland.
Yet he could now win a trophy there in just his 19th match in charge of the Gunners.
The north Londoners have stagnated since their last league title triumph under Montemurro's stewardship and drifted behind Chelsea and Manchester City on domestic fonts.
Eidevall, though, has made Arsenal a difficult proposition through their high pressing and direct counter-attacking football, transforming the side into title contenders once more.
Chelsea eye history at Wembley
The FA Cup presents an opportunity for Hayes' side to create history, becoming just the second club to achieve the domestic treble having already secured the WSL title and Continental Cup last season.
She's no stranger to history either, Hayes was assistant manager to Vik Akers at back in 2007 when they became the first side to win all three dometic competions before adding the Champions League for a stunning quadruple.
The Blues suffered a 4-0 Champions League final defeat to Barcelona earlier this year, missing out on their first European title and a chance to replicate that feat.
Hayes' squad has star players such as Sam Kerr, Bethany England, Fran Kirby and Guro Reiten who all know about scoring goals on the biggest stage.
Their failure in Europe may have been humbling but it could prove to be a valuable learning experience as they face up to in-form Arsenal.
Chelsea's recent loss to Arsenal came in the opening game of the WSL season but we all know form goes out of the window when it comes to these incredible moments.
FA Cup final history is waiting to be written and with two top sides having their own incentives we could be in for an enthralling encounter.
