Personally, I don't care for oil money. I want an ownership that:
- doesn't saddle the club with debt
- allows the funds generated to be re-invested into the club
- cares about football success, not just the money
- is vaguely ethical (no money laundering or tax evasion, no promoting regimes that use slave labour and punish homosexuality with death etc.)
- doesn't interfere with the management of the football side and it allows the football people to make the footballing decisions
Saudis or Qataris would definitely meet my first 3 criteria. Potentially, depending on the owner, the 5th too. Would most likely fail the 4th.
Ratcliffe is most likely to meet all 5. Being a lifelong fan he's only probably at risk of breaking number 4, interfering with football management. It's the least amount of risk. I'd take that.
