I'm really liking the historical, quasi-biblical, philosophical leaning you're on today. It's a similar lens that I tend to look through (not sure that's good news for you...), and it makes this period as a Utd fan at least somewhat more bearable...
These are fascinating times we're in right now as a club, with lots of historical and societal overtones.
I remember very clearly when SAF retired noting that what he'd created was essentially a cult of personality, and historically, when the 'leader' leaves such a post, a vacuum is created by their absence.
The only way to avoid this is to replace them with a similarly huge personality, in our case the only person who was capable of doing that (and enjoying having such focus put upon them) was Jose, but that didn't happen and so the vacuum started spinning...
It ate Moyes, and it's looking increasingly likely that Van Gaal too is beginning to disappear into it.
If Van Gaal's capitulation continues (and it is a capitulation), I really feel that a rising manager is the answer, rather than a plateauing manager (Moyes) or a 'risen' manager (LvG).
We need someone who comes from the modern game and who, if things go well, can give us a good 10 years or so.
