He's quick, has a great engine and runs with the ball at full pace very comfortably. Will he get caught out of position? Undoubtedly. At his age, is that something Ashley Cole and Leighton Baines can improve on the training ground? I'm pretty sure it is. The, admittedly few, games I have seen him play in lead me to think he has every chance of stepping up when called upon.
I don't think he will start the season as first choice, but, I'm fairly confident that he will finish the season as first choice.
