Marcus Rashford
The youngster started last season in the left wing position for United, but ended the season playing as the number 9. It will be interesting to see if Jose Mourinho will put the Englishman on the wing to start or keep him as the back up of Romelu Lukaku. At times, he was very successful out wide but also it looked like he needs some more experience as he would lose the ball sometimes. Maybe this is the season he gains that knowledge of when to pass and when to take on defenders and can be extremely successful on the wing.
