The more I think about, the more I think this is a bluff by these big clubs....this is simply another way of moving the goalposts again, and getting themselves a new deal in the Champions league...
Just look at England....once it was the Sky 4, and they were fairly well protected as far as Champions league football and money went....then City came along, now its 5 clubs fighting for 4 spots, thats doable....
then suddenly Leicester broke into it, Spurs broke into...now its 7 clubs fighting for 4 spots...
then we get money, and have closed the gap, now its potentially 8 clubs fighting for 4 spots....big problem...
currently Liverpool, Arsenal and Chelsea (3 of the original Sky 4) are now out of the CL places....financially they can't have that....so they're fighting to change the rules again...give us more money, but also give us more CL spots...
Ultimately I think that's what will happen...UEFA will back down, and give these clubs more money and more places...and the PL will happily go along with it...
The 3 main leagues will get extra CL places, and life carries on....
UEFA and various FA's will not like it, but I don't think they can afford to lose their top clubs (will they simply cant sadly)...its a kick in the balls to them and us fans too, but we may have to live with it...
