Too often, United look like a bunch of expensively assembled individuals who grind out results than a well-oiled team, a consequence, to a large extent, of a clash of so many different managerial styles in such a relatively short space of time that has led, as one observer put it, to a Frankenstein-like squad.
No one looks more confused at the moment than midfielder Paul Pogba, whom Mourinho still seems unsure about how best to utilise and who was substituted for the second successive away game on Sunday after following up a sorry showing in the 2-0 defeat at Spurs with another forgettable outing in the 1-0 loss at Newcastle.
Graeme Souness, the former Liverpool midfielder, once again reiterated the view at the weekend that Pogba cannot be trusted in a midfield two, especially in bigger games, and the evidence certainly suggests the £89 million Frenchman is at his most effective on the left of a midfield three with less responsibility defensively and more freedom to drift wide.
He thrived at Juventus playing that role and his best performance for United this term came in a similar position in a 2-0 win against Everton last month.
Why can’t Jose Mourinho get the most out of Paul Pogba?
Where have the goals gone?
Mourinho claimed United could have played for another 10 hours against Newcastle and not scored but his side’s problems in front of goal have been building for some time.
