I'll say it again, the mistake we made with Rashford was not being realistic about his abilities from the beginning.
The lad that came through the Academy was a very raw winger/wide forward who was a proper athelete and had a belter of a shot. However, his all-round technical ability was never great, in terms of passing, first-touch or ball control.
What we convinced ourselves we had was an Mbappe, or even something like a Sancho, i.e. a technically very adept player who could play anywhere across the forward line.
Had Rashford received proper guidance from a young age, he could have become a Vardy-type forward. Direct, aggressive, lightning quick and a great finisher. Or, we could have had a "Kanchelskis" style winger, someone who gets his head down and sprints from the byline.
What we have currently got is a player who really doesn't play any position particularly well, but that's not to say still there isn't a player in there. For me, we just need to keep hammering hin to be as direct as possible, with and without the ball.
