When he has played he has looked good, he has the physical attributes, in that he is fast, and strong enough to hold the ball. His passing is good, and he likes to get forward and is good at delivering crosses into the box.
Defensively he is ok, still learning his game, but tackles well and tracks his man. When he has made mistakes his speed has got him out of trouble. Is he a world beater? No, but he is good and with the potential to get better. I would start him over Young.
