I've maintained for long this is the likeliest outcome, in my opinion. It stems from my belief all of this was never about investment into the club, but instead a way to resolve the dispute between those Glazers that want to sell and those that don't. Each of the Glazers could sell a part of their stake, how much percentage will vary between each of them. Some might pull out entirely. Elliot in turn get part ownership of the club, alongside the remaining Glazers, likely Joel and Avram. The class shares system could be restructured to allow for this. But Elliot would delegate all running of the club to the Glazers anyway as they aren't in the business of running clubs, and would likely have many contingencies within the contract for every possible scenario.
That way everyone gets what they want, more or less. It's ultimately a game of compromise. Those Glazers that want out compromise by getting somewhat less money, as I imagine Elliot would offer less than Qatar for their shares, but resolve the impasse and get money now, particularly if it's true some of their other businesses are struggling. Though, you shouldn't count out some sort of an in-family deal between the Outers and the Inners to make up the difference in cash as well. Joel and Avram on the other hand compromise by taking on an increased risk and ceding some power, but they remain part owners and in charge of the club. Elliot always win the end. If the Glazers succeed, club value increases. If they fail horribly, Elliot could likely oust them and strip the club, or just sell it on. Of course, they could also agree mutually to strip the club completely in due time and split the money accordingly. The club owns many assets, not the least of which a lot of tasty land.
My point is there are many, many ways for a deal to be reached between Glazers and Elliot, some we can't even think about or be aware of. As it stands, I think this will be the outcome here, unless Qatar come in with an offer that no sane person will reject. And as it happens, the Glazers have made sure to emphasize that point - £6bn.
It's what I believe, at least. But I sincerely hope I'm wrong.
