#1 Paul Pogba
The likes of Jesse Lingard and Ander Herrera maybe vital to United' hopes, but none more so than Paul Pogba, who's breathed new life into his season in the recent weeks.
The brace against eventual champions Manchester City in the derby win has to be his peak, for he surely was the best player on the field.
In a season where his stats haven't shown as much as they did last season, only compounded by verbal spats with manager Jose Mourinho, the fact remains he was a key figure all the while.
He's won the man-of-the-match award six times, the most for any United player, and is also the best-rated player for the Red Devils on Squawka.
Remember when I said Matic has freed-up United's attack? Well, the biggest beneficiary of that is Pogba himself, who's assumed an expansive role in the midfield because of it.
He's able to get into deep-lying positions, and even if he plays centrally through the midfield not attacking, the game against City showed his offensive proximity.
