I don't think he's going to stay as the left sided player for much longer, his next evolution of his ability will be to move to the focal point up front incorporate his ability in space on the flanks and the channels, supplementing that with proper creative players in all three positions at 7/11 and 10. He can run, sniff out goal scoring positions off the ball when we have it and finish moves without the burden of relying on the weakest aspect of his game at the moment which is his creativity in general. The mistake might have been mentioning martial having to make way. It seems the usual crew from his thread have shown up to feign personal disgust on his behalf.
I think that will be the next evolution of this team going forward over the next three to five years, we'll see if it happens or not. I'd much rather have specialist players playing in specialist positions going forward and right now Rashford has shown where the evolution point lies in my eyes, even though the attack as a whole has been wildly inconsistent this season we have strikers playing everywhere, central midfielders on the flanks, flank players in the hole and up front. The whole thing is a bit of a mess and that has borne out in the wider results across the season. It needs streamlining and bolstering and if we're going to be honest about having one guy up front it will more than likely be Rashford. We'll see though, right now he's a delight to watch and will easily be our player of the season.
