The thing is, they've spent United money. Not any of their own money or any of the money they've syphoned out of United since they "bought" the club.
We don't need them to spend money from their own pocket, because then they'd find some ways to recoup those money later anyway. It's perfectly fine if they only spend United money. What we need and cry for is them spending it wisely and be more responsible.
The way they have run United these past years is like those rich parents who just pump money to their kid and the serving maids, thinking that alone makes them great parents. The truth is the opposite. Their "child" (Manchester United FC) needs better care and correct guidance from them, not just senseless money being pumped in with no coherent direction. And Woodward is like that private tutor of the kid who only got the job because he is close friend with the parents. He helped the kid got in fancy clothes, events and various "trendy" institutes just for the image, without actually looking in to see what's best the kid's development.
I know the comparison may put some people off. But that's how I see United under the Glazers and Woodward's leadership. We don't lack money. We lack direction, and accountability in leadership. I still dislike the Glazers due to all above reasons, but I think they deserve time to show how the new "spine" of leadership (Arnold-Murtough-Erik-Rangnick) would work.
I'm liking what I see so far, ever since Arnold got appointed. The way we approached Erik/Pochettino (With due process, interviews...etc instead of jumping on the bandwagon) and the way we handle players who are out of contract (Taking back Pogba's offer) make sense. In a way, we can say that the board has earned themselves this summer.
