I don't see how it's a win/win because ETH and co. could fukk up the next 1-2 seasons and all the while the rest of the superpowers are getting stronger.
INEOS will be building the team NOT ETH.
ETH is a good sacrificial lamb. if he fails they can blame him. if he succeeds INEOS take the plaudits.
why waste a new manager's rep sorting out the mess? a mess that ETH and OLE contributed massively to.
the new owners can sort out the squad mess (in the background) and give their eventual chosen new manager a clean(-er) slate.
also some young promising managers need a year or two to prove themselves in the EPL - frank, mckenna.
