Here's one for starters.
New owners can attain loans, but only as a percentage of their turnover. If they want to borrow more they can, but it can't be levied as debt against the club.
If they want to invest their own wealth, they can but it has to be converted into equity.
This will stop reckless owners gambling their club's futures away, & wouldn't limit ambitious but sensible owners from investing their personal wealth into their clubs.
The nonsense UEFA told us in 2012 has proved unworkable bollocks. They suggested that we invest in youth & grow our playing squad organically over a number of seasons until we could challenge.
Absolute bollocks! Look at Leicester. Within 2 seasons of winning the PL, they were asset stripped. Kanté & Drinkwater went the Chelsea, Maguire to ManUre, Mahrez to City, with only Vardy resisting Arsenal's advances to remain & Chilwell also moving to Chelsea but a bit later.
Seven years after their unlikely PL win, Leicester were relegated to the Championship. That says all we need to know about building a squad organically.
You either become a nursery, or a feeder club for the CL chasing clubs as Leicester found out, & similar to what's happening to Brighton now.
It only takes a couple of bad seasons & a weakened, underdeveloped squad until those clubs could be scrapping against relegation rivals for PL survival.
