I have no idea what to make of this man.
He's capable of making runs behind the defensive line, thats good. But when he's on the ball, he's just so... worthless.
Now, I've seen him be good, mainly when he's up against lower teams, but how do you go from that to just be so crap. I mean, when he's up against lower team's defence, he uses his speed. Then when he's up against a Premier League team, he slows down and tries to beat a defender by standing still. How have he worked that out? Wouldn't he try to use his speed even more when he's up against a better defender? The player he's up against in a PL-team isn't automatically faster. He's probably smarter, but not by any means does he have to be faster.
He should really try to use his speed more. He should also work on his turns and changing of tempos.
Look at Rashford. He's not the quickest (still quick though), but he uses his speed and change of tempos to get past his defender. Smart kid.
