Let them make the Champs League closed doors. Everyone just stop paying for it on the TV will mean they have to stop. If they do that then why don't Rangers, Celtic say to other big teams that wouldn't be in it, The West Ham's, PSV's, Napoli, Stuttgart why don't we make our own league? Rather watch Man Utd vs Real Madrid every year or see Rangers play the likes of other huge teams that wouldn't be in the competition?
The gates would be packed every week and sponsorship's would be massive!
