5 reasons why Chelsea will thrash Manchester United in FA Cup final

#2 Injury woes

Lukaku

At least three of Manchester United's key players are fitness concerns ahead of the all-important final tomorrow. Romelu Lukaku has not featured in United's last three games, but while the Belgian has been passed fit, it remains to be seen if there is any rustiness in his game.

Meanwhile, Anthony Martial missed the Watford game due to a knee injury and despite travelling with the squad, doubts linger as to whether he will be able to take the field.

Marouane Fellaini too missed United's last two league games. The Red Devils do have adequate backup, but Chelsea will be buoyed by the fact that Mourinho's men are not in prime condition.
