The expectations placed on him far outstrip what can be delivered in the short term.
Ordinarily you’d expect a new manager to come into failing team. In this case, I think broadly speaking the fans were generally content, with green shoots starting to flourish. So straight off the bat, Manning isn’t faced by a low bar.
Coupled with the nonsense talk of “top 6 squad” (to paraphrase, before people pick up on the semantics) he has to deliver results while being dealt the same hand that Nige had, with the added complexity of the impact that the upheaval has on the squad.
