This is going to look like one of those games where you have multiple choices to combine options into a whole but with limited amount of money.
You have 10 bucks
1) Owner who cares - 5 bucks
2) Owner who has sufficient money - 6 bucks
3) No shady consortium or oil money - 5 bucks
4) No sportswashing, human rights violations etc. - 5 bucks
5) CEO is United fan - 4 bucks
We could potentially walk right into another Glazers situation if an US company takes over. Also, since the current owners will just sell to the highest bidder, it will be hard for anyone to compete if an Arab state steps up.
