For Chelsea the FA Cup final presents Antonio Conte with the chance of guiding the Blues to a league and cup double during his first season in English football.
For Arsenal and Arsene Wenger, it is an opportunity to salvage some respect after a disappointing season in which they have failed to qualify for the Champions League for the first time in 20 years.
There are plenty of subplots, too. Chelsea legend Petr Cech will be in the Arsenal goal, looking to foil the club that he won 13 trophies with. While former Gunners skipper Cesc Fabregas could line up in the centre of the Blues midfield.
Chelsea, fresh of winning the Premier League, are understandably favourites to win the match. But Arsenal are more than capable of upsetting the odds and clinching their 13th FA Cup triumph.
We've looked in detail at the five big talking points ahead of the match…
Arsenal's defensive woes
Wenger has a big problem to solve ahead of the game. With Shkodran Mustafi a major doubt, Gabriel ruled out through injury and Laurent Koscielny suspended after the ludicrous red card he received against Everton, the only centre-backs the Gunners have available are Rob Holding and Per Mertesacker.
It would be some ask for the German given the only football he has played this season was the 37 minutes he gained against Everton at the weekend. But, given he is still club captain, you sense that if needs must the 32-year-old will be able to get through 90 minutes.
If Wenger opts to stick with the back three he has been using since the middle of April, he will have to play one of his full-backs out of position. The most likely candidate Nacho Monreal, who has played in the role on five occasions.
The Gunners boss could, however, surprise Conte by reverting to a back four if Mustafi is unavailable. It would mean a return to right-back for Hector Bellerin after a spell at wing-back which has helped the Spaniard regain the confidence that had ebbed away earlier in the campaign .
A chance to say goodbye?
Saturday's game could be the last for several players. For Arsenal, Alexis Sánchez and Mesut Özil go into the summer with their futures uncertain.
You'd expect the Germany star to sign a new deal but the FA Cup final may be the last time Sánchez wears an Arsenal shirt.
The Chilean has shone for the north London side this season. He is their top scorer with 29 goals and has also supplied 19 assists. But with no Champions League football on offer next term and only a year remaining on his deal, it's likely the 28-year-old will move one.
He is reportedly a Bayern Munich transfer target while Chelsea and Manchester City are also interested.
The Blues are in a similar position with their top scorer Diego Costa. Reports persist that the Spain international will leave Stamford Bridge this summer, either for the Chinese Super League or for a return to former club Atletico Madrid.
Conte is believed to be urging the club to offer Costa an improved contract to keep the 28-year-old in west London but if the right bid was made then the Blues may cash in.

John Terry's last hurrah
Like him or loathe him, Terry will undoubtedly be missed when he leaves Chelsea this summer after 22 years with the club.
He could make his last appearance in a Blues shirt at Wembley… but only if he is brought on as a substitute.
Conte has shown over the course of the campaign that he has no room for sentimentality when it comes to his team selection. The Italian will pick the strongest side possible and that no longer contains Chelsea's captain, leader, legend.
But, if the game is won with time to spare, Conte may opt to give Terry one last cameo appearance. It would allow the 36-year-old to have one last farewell and would make lifting the trophy alongside Gary Cahill easier to stomach for a lot of his critics.
While the future of Arsenal's two star players remains in doubt, there is still uncertainty as to whether Wenger will stay with the club beyond this season.
He's current deal expires at the end of June and over the last six months the Gunners boss has played a game of will he, won't he with the media and, seemingly, the club's board.
Wenger himself has admitted the uncertainty over his future may have affected Arsenal's performances since the turn of the year and yet, still no announcement has been made.
A new two-year is believed to be on the table but if Arsenal are able to surprise Chelsea and clinch the FA Cup then Wenger could shock everyone but leaving on somewhat of a high, although it is unlikely.
Fabregas can vindicate his decision… again
When the Spanish midfielder left the Emirates in 2011 for Barcelona one of the key reasons behind his decision was that he wanted to compete for league titles and European trophies.
At the Catalan giants he did just that, claiming a LaLiga title, the Copa del Rey, the World Club Cup, the UEFA Super Cup and two Spanish Super Cups.
But after three seasons at the Camp Nou, Fabregas had itchy feet and wanted a return to the Premier League. Arsenal had the first option on resigning their former captain but opted against it.
Chelsea made their move and it's not one they, or Fabregas, have regretted. During his time at Stamford Bridge, the 30-year-old has won two Premier League titles and a League Cup title.
If he can add an FA Cup winners' medal to his haul then, as much as it will pain Gunners fans to admit, Fabregas made the right choice in leaving six years ago.
