Let's be clear, he didn't preside over 4 managers getting sacked. And he's not the only culprit.
But he's the only one - or at least the only one left - where it's not necessarily his ability that's the problem, but instead his attitude.
There are players there I don't think are good enough for United, and it's probably no surprise I put Rashford in that camp. I make no bones about that.
But none of them, bar him, has an attitude problem. None of them do you see sulking around the pitch, phoning it in. They might not be good enough, but by and large they give it a go.
The most egregious thing about Rashford is how he uses the goodwill automatically bestowed upon him as an academy graduate to coast and skive. Man's 27 now. 27 and we cling to the idea he's had a "decent" game if he puts in a cross or spends 15 mins doing some work defensively. We simultaneously stratch our heads wondering where it all went wrong.
