Saturday's game will be the 137th FA Cup final, with both sides in dire need of a victory as they look to end the season on a high.
Looking at their performances in recent weeks, it would appear that United are at their best when teams come at them. It is no secret that Jose Mourinho is a huge fan of solidity and dislipline, with their still plenty of quality in the 'Red Devils' squad to pick teams apart when they overcommit.
That much has been evident recently in the wins over Manchester City and Tottenham, two sides renowned for their proactive approach and desire to play the game in the right way.
At teams attack, there are invariably more gaps for United to exploit, allowing the likes of Paul Pogba, Alexis Sanchez and co to create and wreak havoc, with the pair instrumental in the aforementioned victories.
With that in mind, it would perhaps suit Chelsea to sit tight themselves and force United to try to play through them, something which they have struggled to do on occasion this season.
Mourinho's men famously failed to pick up a single point away to all three promoted sides this season, whilst the 'Blues' demonstrated their menace on the counter attack in the Champions League against Barcelona, suggesting that it may well be their best option at the home of English football.
Despite the damaging defeat to Newcastle last weekend that saw them miss out on a Champions League place, Chelsea actually go into the final in better form than their rivals, with a draw against Huddersfield the only other blot on their copybook in the last five games, compared to a United sie who have suffered defeats against both Brighton and West Brom.
Nevertheless, the continuing speculation over the future of Antonio Conte could derail Chelsea's preparations, especially with a serial winner such as Mourinho in the opposite dug-out.
Whether you are a fan of the Manchester United boss or not, there is little denying that he is a man for a big occasion and though it may have lost its shine slightly in recent years, there are few bigger occasions in English football than cup final day.
Finally, Mourinho's adaptability and willingness to change system at the drop of a hat if things aren't going right is also another major advantage of his, with the former Chelsea boss lauded for his tactical tweaks as United came from behind to beat his former club back in February and again as they recovered from a slow start to see off Spurs in the FA Cup semi-final.
Contrast that with Conte's refusal to change tact as his Chelsea side crashed to a limp 1-0 defeat to City in March and it is hard to see the Italian coming out on top if Saturday's game descends into a tactical one-on-one.
