Forever, providing it's in your best interests. As I keep saying, the vast majority of owners and those that run these oraganisations are only in it for the money - the motivation for the decisions they make will be financial.
I disagree, I don't think either Chelsea or man city owners are in it for the money, it's their play thing.
Its the American owners that are the problem Glazers. Kronke and FSG. They don't like the fact that a pretty much nailed on top 4/5 has expanded and they don't like missing out on the CL money.
With Bayern giving a firm no I don't see how this can work as no European clubs are going to risk the potential fallout for not a guaranteed spot. So it's a league of 12 not 20, pretty boring of you ask me
