I disagree mate.
Firstly, let’s look at what they’ve done well. They’ve monetised the club to a much greater extent than it was when they took it over, but that arguably would have happened anyway, at least to a similar extent. They have invested heavily in the playing squad in the last 9 years, but most of the money has been wasted. Prior to that, they hugely underinvested in the playing staff (‘no value in the market’) which is what started the decline on the pitch from which they’ve never really recovered.
On the other hand, they have made a series of poor senior appointments both at coaching and corporate level. The money men you speak of are overseeing an institution in huge decline. The lack of investment in the infrastructure of the club, especially the stadium, speaks of owners with no vision or discernible plan. Despite generating more revenue than any other club they have declined hugely as a force in the last ten years, on their watch. No big players, other than those in the wane, want to sign for them any more.
No other club in European football has such a poor track record versus money spent in the last decade, all on their watch. The managers that keep failing, despite the money they are given, are all on the Glazers. As is the decaying state of old trafford.
This is all, ultimately, on them.
And on top of all this, and their dreadful decision making, is the money they have milked, and continue to, from the club.
As a City fan, obviously they are decent, but objectively they are terrible owners. Offspring of a self made made without his street smart and wherewithal. They are fucking clueless.
And long may it continue.
