The second elephant is Rashford, who as far as I am concerned is distinctly average. United have turned him into a valuable media asset, and now can't afford to lose him. He needs to be in the media spotlight for PR and commercial reasons, so they must continue playing him.
As for those who think there is a top class player waiting to emerge from Rashford in the hands of a quality manager like Pep, I just don't see it. Good managers generally take good players and make them better. Occasionally they will take players with potential and develop them. They rarely take average players and develop them into world-beaters.
Rashford has reached his peak. He now needs to spend the next few years there, being average, until they offload him to a mid-table side. He is the new Lingard.
