My problem with him is I don't know how to utilize him from the start of the game.
Wings? He isn't much of a threat because he's not explosive like Olise, Saint-Maxim etc. He has the trickery and good touch but that is useful when we're playing against teams sitting deep. It's also easier to pin teams back when they need to worry about the likes of Rashford.
Central position/#10? Offensively he's well suited to that role, but his work rate off the ball is missing. He doesn't seem to sense danger as well, just strolls around midfield areas.
Striker/false 9, I don't think so. I don't think this is the way forward for the team anyway.
As talented as he is, I think we should consider selling him if he can't improve on his mentality/fitness by the end of the season. I think we might get some decent money for him still.
I would also be ok if he stays but I don't think ETH trusts him much. Yesterday he went for Antony from the start, even though he just got back from injury.
