It's not a very wise investment for anyone, unless they have bottomless pockets (which basically means you want a Gulf state to buy us, which many wouldn't be keen on).
- It would cost a lot of money to buy us
- The intrinsic value of the club is in its Premier League status, which will never be a long-term given
- The stadium paradox where it's simultaneously effectively worth £0 but also needs major investment at some point
- The natural glass ceiling that a medium-sized provincial club hits
"Just sell us" is as reductive a statement as "sign a striker".
