You're absolutely correct, there is no way to tell, today, if a law has been broken. Mazeltov on the semantics win. Internet award of the day goes to you.
So how would you describe Chelsea's spending then? How would you feel if you were a fan of any of the other 19 teams in the league, who are now supposed to compete with Chelsea. Spurs, Arsenal, Liverpool, United - these teams cannot spend like Chelsea are. Simply can't, they don't generate enough revenues.
Given your tone, I realise you don't care, but a more mature response would be to consider at what stage this is even a competition. This year it's Chelsea. Then next year Pep leaves and City spend 1 clean billion. Buy 20 new, world-class players. Then Newcastle get uppity, and do the same. None of those clubs can 'afford' to spend that much. They're entirely dependent on subsidies from their rich owners. In my naivety, I had thought FFP was designed to prevent clubs spending like this, because if Boehly gets bored, got too hard into crypto or whatever the real risk now is the end of CFC. That's what FFP should be trying to stop.
In my opinion far larger steps should be taken to make this a 'league' again like proper sports, but that's for another day.
