United know that the biggest mistake they can make this summer is to go against the wishes of the new man in charge. If gradual change is to be implemented, then it is Ten Hag who must be given blind backing for this summer at least.
The club must continue to show their full faith in the new manager, even if they have obvious doubts.
This is mental. If United's approach to transfer policy is to blindly support a new manager, then they're just replacing one kind of dysfunctionality with another. This is what you have a scouting dept and a DoF for. If your approach is to give the manager everything he points at, then those are irrelevant. And it really isn't doing EtH a favour. If you want to help EtH, then do your fecking jobs properly and don't ask him to sort out problems that other parts of management should be on top of.
Obviously EtH wants the club to do well in the longer term, but a less than well entrenched manager inevitably and always has his own survival as the most pressing immediate concern, and that will skew such decisions. We've seen that before, f.e. with OGS preferring to hang on to Lingard because he wanted the depth. A decision that was mad from a personnel management point of view, never should have been allowed to happen and wouldn't have happened if we had a functioning management structure geared to the right priorities.
Just listen to what Pep Guardiola says when he's talking about these things. He's clear what he thinks and what he wants and that this is known to management, but he's also very clear it's not really his call. You never hear him complaining about a signing and there's nothing to indicate the club isn't listening to his views, but at the same time he also isn't complaining when the club won't go above their valuation for Cuccurella, or demanding that they hang on Bernardo Silva. It looks a lot me like he's happy enough to let the people whose job it is to get on with handling player movement, confident that they're on the same page and that they'll handle it well.
