Antonio Conte's future looks to be hanging in the balance after his side failed to finish in the Premier League's top four, just 12 months after winning the title.
However, his side is available at 9/5 (2.80) with dabblebet to restore some glory by coming out on top in the final.
Having enjoyed a more successful league campaign after finishing as runners-up to rivals Manchester City, the Red Devils can be backed at 17/10 (2.70) to claim their third major trophy in two seasons with a win in 90 mins.
Just one of the last eight encounters between this pair has resulted in a draw, but you can get odds of 21/10 (3.10) on them taking this one into extra-time after a deadlocked 90 minutes.
David Luiz and Ethan Ampadu aside, the Blues will head to Wembley with a fully fit squad to choose from.
Romelu Lukaku faces a late fitness test after missing the last three matches with an ankle problem, while Marouane Fellaini and Anthony Martial are also injury doubts.
Given how worryingly his team's performances deteriorated in the second half of the season, it seems that even FA Cup glory will not be enough to keep Conte at Stamford Bridge.
Although a mini revival resurrected slim hope of leapfrogging Liverpool into the Champions League places, a frustrating 1-1 draw against Huddersfield and abject 3-0 defeat at Newcastle saw the season end on a gloomy note.
Having lost four of their last five games against the rest of the Premier League's top six, it is hard to see Chelsea bouncing back with a winning performance against Jose Mourinho's men.
In contrast, United have won each of their last five matches against the top six, and are well worth backing at 17/10 (2.70) to compound their rivals' misery with a third cup final victory in two seasons.
