Wait, Glazers have to return the original loan they borrowed to buy the club in 2005 of around £500-600m by the end of 2025? If this is true, I didn't know this(dumb from me).
I'm not an expert in economics by any means, but could they just borrow more money(create new debt) in order to repay the old one(I think that's called Ponzi's scheme in economics, if I'm not mistaken)? Interest rates would be pretty high again, I suppose, and the club desperately needs some serious cash injection(s) in order to survive(near the top of the game, at least), plus the complications with tightening FFP rules.
This "strategic review"(sale) might be more complicated that I initially imagined - I wasn't informed enough. Glazers might have even less leverage than I previously thought they have. They'll either have to pull some sinister, genius financial trick/scam(which they might just be perfectly capable of - they're very foul, grotesque, wicked, financially crafty people), or they'll have to be gone pretty soon or the club completely collapses.
It looks like we're in the endgame right now - Glazers might be backed into a corner and there's no escape, other than the sale.
