Ah, I see what you mean. I understood something different by what would cause the change. That would certainly be news, but I'm not sure there is much better than the current situation, based on where we are - look at cricket which is totally controlled by the biggest three, and rugby union where the English clubs are constantly bleating for more.
I don't think UEFA are under control of G14. I just think they are being pressured by constant demands - clubs and broadcasters - and haven't found a way out of it yet. It's not quite the same thing. Influenced, yes; controlled, no.
I don't put it at Ceferin's door, I think it's been ingrained for years, ever since they started mucking around with the CL structure at the behest of the cash-hungry.
