IMO his movement and instincts are that of a central player, not a wide player. His dribbling and touch and style is good playing centrally and being a box player. He's not a creative player at all, he's a decent dribbler but not when it comes to dribbling like a winger should to get past players, and he doesn't have good movement as a winger. Rashford has great movement as a wide player, but he doesn't as a central striker. I'd be shocked if he developed into anything as a wide player but think he'll be a world class striker. Just takes time to learn that position and be able to handle it properly. Very rare for young players to come in and be able to play as a central striker to such a high level like Haaland has managed to do.
We don't really play with wingers that are expected to dribble to the byline and whip in a cross or beat their man that often. Beating the defender is secondary to being able to find space in-between the full back to make a run or simply working a position to shoot - which he is pretty good at. Most of his goals have some from a good piece of play where he has worked space from a wider position and got his shot away - albeit teams now understand his strength. If that is one of his strengths why are we so keen to say he should move away from those positions to one where he is sat on 2 or 3 central defenders, often back to goal?
He needs to work on his runs and positioning generally, is it really position specific? That's a skill that can be developed and often is for young players.
I think he'd be considered a little more creative if the numerous opportunities he's provided from pretty impressive crosses had been taken, but alas we lack natural targets and we've fluffed them. He certainly has the technique on the ball. You're right that he's currently more of a goal scorer than a creator but I see enough to think he can develop this, at least to some extent.
I don't see the hold up play, the heading ability, the willingness to run channels, that many goals scored indicative of somebody that loves being in the box. You might say he hasn't had the chance, but it's also why I ask..where is the evidence he's going to be a striker? I look at somebody like Hughill, there is no doubt that if he makes it here he will be a striker, there is no other possibility. With Greenwood given his overall skillset, it's at least a massive question mark.
