#3 Manchester United's squad depth

With Romelu Lukaku and Anthony Martial still doubtful for the clash, do United really need to worry about not having a forward to spearhead their attack? No.
Should Mourinho opt for a 4-3-3 formation, he will still have a trident of Alexis Sanchez, Jesse Lingard and Marcus Rashford who can adjust well in the attack, with the former two playing wide roles.
Or else, he can even use a 4-2-3-1 format, with Lingard as the lone striker, Herrera and Matic in the defensive midfield position and three out of Sanchez, Pogba, Rashford and Mata in the remaining roles.
That goes to say that United's squad depth and the versatility of the players will be a key asset for Jose Mourinho in his bid to clinch the FA Cup title.
