888Sport go 15/8 (2.88) that Chelsea win the match in 90 minutes, the draw is 21/10 (3.10) with United chalked up at 8/5 (2.60) secure a victory in normal time. The same firm are Evens (2.0) about Antonio Conte's side lifting the trophy (including wins via penalties or extra time) and 17/20 (1.85) on the marginal favourites adding another FA Cup to their trophy cabinet.
The big question mark for Manchester United is the participation of Romelu Lukaku. The Belgium international hasn't featured in any of the previous three matches after picking up an ankle injury against Arsenal. Anthony Martial and Marouane Fellaini are also injury doubts for Mourinho's men.
Chelsea will be without Danny Drinkwater and David Luiz but other than those longer-term absentees, Conte should have a full squad to pick from.
The bookmakers certainly don't expect a goal-fest at Wembley. Under 2.5 goals is just 11/20 (1.55), despite three of the past four finals seeing three or more goals in normal time.
Dele Alli's strike in United's 2-1 semi-final win was also the first FA Cup goal that the Red Devils have conceded in this season's campaign and Chelsea's defence has only been breached just twice.
The head-to-head record of these sides certainly backs up the argument for opposing goals too. Both teams have scored in just two of the last eight meetings and with silverware on the line, this is expected to be another cagey encounter.
One factor to consider is Jose Mourinho's record in these high-pressure clashes. The Portuguese has won 12 of his 14 previous major European and domestic finals as a manager (excluding Super Cup games) and is a perfect six out of six with English clubs.
By contrast, Conte has lost both his appearances as a manager in finals - including last season's FA Cup final, of course.
It might not be the thrilling contest that some would wish but it's tough to make a strong case for a Chelsea team that finished 11 points behind United in the regular season and showed so little fight in their 3-0 defeat to Newcastle to close out the campaign.
Given Mourinho's extremely impressive stats in major finals the 17/20 (1.85) on Manchester United equalling Arsenal's tally of 13 FA Cups looks a solid option considering it keeps the possibility of a win via penalties or extra time.
