This is a novel debate certainly not seen this discussed before.
We have a team full of people who don't perform in any aspect, yet a certain section of fans care more about replacing those who do excel in some (De Gea, Ronaldo, Bruno).
That's been a key mistake of United's for years though.
The team should be greater than the sum of its parts.
Which doesn't mean going out and buying good players in every position in the hope they will somehow gel. Or keeping players that excel in some areas but don't make the team better.
Not once has a manager since Ferguson come in with an overriding philosophy of the style of how they want to team to play and then had time to bring in the players to fulfil that.
Ten Hag might be given that opportunity. But what if he decides De Gea, Ronaldo and Bruno aren't the right players to achieve what he wants? Will the club back him?
It's far more likely that he comes in with a certain philosophy and then is told that he needs to somehow magic the players you have already to fit within that!
So you dilute any impact he can have by backing the players that have already been given long contracts, on ridiculous wages. Then he doesn't get the results, he's under pressure and you rinse and repeat what's been done post-Fergie. A 'new direction' every few years that just leaves you going round in circles.
