What planet are they on!?!
Why would the Glazer's sell/give up their cash cow? Ever?
Only when their supporters stop going/stop buying stuff, will the Glazers think about selling, and even then, they could just walk away as it crashes and burns, as the debt is owed by United, not the Glazer's. They''ll never give it away/sell to 'supporters'.
The only alternative is a takeover, but who would want to spend X million/billion, on a club that has:
1. So much debt and cost too much for a 'name'
2. A not fit for purpose stadium with nowhere to expand/change
3. Old mercenaries creaming off the money
4. So much local and international 'stakeholder' anger
As the Who sang, if a takeover happened, it would inevitably be:
'Meet the new boss
Same as the old boss'
