#5 Minimize Alexis Sanchez's impact
Alexis Sanchez has not had a blinding start in Manchester colours but he is finding his feet now. He was one of the most impactful players for United in the semi-final against Spurs, scoring the equaliser on that day.
Sanchez could start upfront as Romelu Lukaku and Anthony Martial are injury doubts or he could be used in his usual left wing position. Whatever the position, he is bound to trouble the Chelsea backline.
Aside from the attacking threat, the Chilean's unending desire to run after every loose ball and harass the defenders will not be welcomed by Gary Cahill and company.
Chelsea will need to keep Sanchez quiet and not present him with any chance to threaten Thibaut Courtois. Cesar Azpilicueta and Victor Moses especially will need to be up to the task, and both of them are more than capable of it.
