I like the proposal personally. Means the “bigger” clubs can’t just chuck money around until they get it right. Seems a fair system and the better run clubs will benefit
All this does is tie the growth of the top Premier League clubs to the growth of the bottom ones. The only way for Chelsea, City, United to spend more is to make the 20th team's revenue grow.
Which means that if the PL invests in growing the lower end of the table clubs, they will kick on and get further away from the rest of Europe as all 20 PL clubs will soon end up in the top 25 clubs in Europe for revenue and therefor spending power.
If they ignore the bottom clubs, the cap will start to limit the top clubs growth and that will help the big European clubs catch up.
It doesn't remove any competetive advantage or allow Spain/Germany to steal players or catch up because they already have their own spending controls which are more strict than this. It doesn't limit how much anyone is spending now because the cap is already way above everyone's current spending.
