By style of player I think United need, I mean a winger who can run with the ball and is relentless in his mentality to keep going and going, has natural talent and the ability to create a yard of space and is a threat for both creating and scoring. His movement is excellent to get in dangerous positions and always be a threat. He needs to improve and he will, but likely will improve more elsewhere because we aren't the right environment for him.
He's young, his end product has been shit. That stuff will turn in time, and especially when there are others to share the load and be the main men. Right now, there isn't another attacker who looks like they can create a chance, score a goal, or even get a chance let alone take it. Without him we provide 0.
On Garnacho himself, I've said for ages now that I think he's much better on the right. His best period under Ten Hag came from the right wing, but Amorim seems to be insisting on using him on the left only. On the right I think he plays more naturally, he lifts his head up and is a smarter player, while on the left he tries to play off instinct to cut in and shoot which isn't the right choice always.
My issue is I love watching wingers who run with the ball at defenders and try to make things happen and cause danger, and I think our system is moving away from that. So I don't like that.
