Agree with Goon here. The kid is clearly very talented. But go out, get the ball, move it around more, drive much more of the activity in the centre of the park, and accelerate the play the way Partey and Odegaard do. Think about how much faster the ball zipped once Partey and Odegaard came on last Thursday. And we scored almost immediately. That's what makes the difference. It's how Wenger's best teams have played. With zip.
I don't think these are things beyond him. You just have to see the quality of his long range passing to know that this is a technically capable player.
