I think from a purely football perspective my favorite part of the Sir Jim quotes were this:
“We’ll decide that style, plus the CEO, sporting director, probably the recruitment guys, what the style of football is and that will be the Manchester United style of football, and the coach will have to play that style. We’re not going to oscillate from a (Jose) Mourinho style to a Guardiola style. That’s not the way we’ll run the club. Otherwise, you’re changing everything all the time, you change your coach, you’ve got the wrong squad — we won’t do that.”
This to me is the crux of everything wrong with United. When you talk about a squad not fitting a manager and needing 3 years it’s because the club just picked at complete random with regards to a style.
No long term thread for how the squad was being shaped, which exists beyond whether a manager survives or not. The next manager continues the vision not resetting it.
That’s how you spend a billion for nothing. You spend it going 6 different directions instead of one.
