4) Anthony Martial - Manchester United

"If he wants to become a very special player – he can do that – then he has to go in a certain direction," Mourinho had said of Anthony Martial last season.
The young Frenchman, who broke the record for most expensive teenager when he signed for Manchester United, was given some freedom under Louis van Gaal but initially struggled in Mourinho's rigid approach.
Competing with Marcus Rashford, Henrikh Mkhitaryan, Jesse Lingard and Juan Mata for wide roles (thanks to Zlatan Ibrahimovic cementing the striker's spot), Martial found it hard to adapt, often leaving full-backs to fend for themselves.
Mourinho did manage to get the best out of him towards the end of last season, especially when they had a very tight schedule in April and May. But following Romelu Lukaku's arrival, Martial will certainly be asked to play on the flank again.
Can he impress Mourinho with a consistent run of games or will he be dropped again?
