Moves are afoot to stop breakaways.
The 50+1 rule is under consideration.
Ultimately these moves will fail because they are trade restraints. Few people in the football hierarchy understand that, legally, the breakaways did nothing wrong.
The first moves should be about bringing debt into ffp calculations. Debt caused the spanish clubs to push the superliga at this moment. Longer term, UEFA must become a regulator only and not a promoter of tournaments. Herein lies a big issue: clubs sit on the executive of UEFA and have a vested interest in shaping those tournaments. The new CL format is an example, more games, co-efficient engineering, protected status for 'legacy' clubs. A regulator should be putting player welfare ahead of money making. So, look to the organization's name and get clubs off the boards.
Many more measures available, but enough for now.
City fans? Demand meaningful fan representation within the club, not patronizing talking shops.
