#2 Mason Mount (19 years old)
Mason Mount is currently working with Frank Lampard, need I say more? The young midfielder showed signs of the Chelsea legend towards the start of his Derby loan move but has since tailed off. Still, there's a gem in the Englishman and it won't be long before he's unearthed.
Mason Mount is a very attack-minded midfielder, this is similar to Lampard. He loves to drive forward with the ball at his feet, encouraging his teammates to do the same. He is also a very good set-piece taker and we all know how valuable this is becoming in the modern game.
Should he continue to flourish under Frank Lampard and then further his understanding with Maurizio Sarri upon his Chelsea return, the fans are in for a treat. The environment is right for him to achieve, he just needs to make the most of it.
