The point is that Leicester won the premiership and fa cup. Played in Europe. Regular top 10 in the league. Can't recall spending over their means. A club like them have a point in time have to tighten the belts. If not, they'll get punished.
There's a financial cap for team like them, like Villa, like Everton so that no matter what success on the field they have unless they find favourable deep pocket deals from other sources, mainly Saudi, it will only get so high.
Wolves spent above their means to survive. Now they have to tighten. If they don't, they'll get punished.
It will happen to all teams apart from Newcastle, City, PSG.
