#6 Anthony Martial
The former Monaco forward become the most expensive teenager since his move from Monaco in 2015 for a fee of £60 million . He has so far justified his price tag with stellar performances.
But since the arrival of Alexis Sanchez things have become complicated for Jose Mourinho, who is having a hard time in managing from his galaxy of attacking options and Martial is suffering as a result.
At the start of the season he was used more as an impact substitute. Recent comments by his agent have further fuelled the speculation that he could leave the Red Devils. His current deals runs until the summer of 2019.
Juventus are said to be interested in the former Lyon academy graduate along with Real Madrid and Tottenham.
