That Abramovich approach works when you have world class talent. We barely have a squad of average players so no idea what we're doing.
And ideally if you're playing Chairman Manager, you'd bring in the younger forward thinking manager, gets backed (Brands does his job) and he's given 3 years to build a team/style. That means keeping with the manager through poor league positions and rocky periods.
But said manager has to be sold to cope and deliver a different agenda. The focus would be on building and not league positions/trophies. The dream would be to do both but then you're looking for a unicorn of a manager or keeping the faith with them for Moyes-like time frame.
Mosh has invested too much to look back and press the restart IMO. He'll want safer hands, someone with credentials, stature, and able to cope in the prem.
If it is Rafael I am very interested in what his ideas and goals are. If he says consistency or foundations to compete, I'll show an interest. If he rolls out the "top 6 champions league" guff then he's doomed to fail.
