#3 Nemanja Matic
Amid all the glamour that came along with Romelu Lukaku, Nemanja Matic has had the ignominy of playing away from the limelight. But to say even he's been a great signing is only an understatement.
The Serbian international has a huge impact on this team. His terrific vision and incisive passes have helped his side move forward with purpose and poise.
In fact, of the 1996 passes that he has laid, 78% of them have been forward, while he has also maintained an admirable record of 87% accuracy with it.
The arrival of Matic has helped the Red Devil free-up in the attack, and he's the foundation that they've built their attacks on.
So his role on Sunday would be one of a propellant. If Matic plays well, then United will play well.
