The transfer ban being talked about is likely a misunderstanding or mis-statement by the journos. The actual punishment/s possible are UEFA refusing to allow a club to register new players for European competition or reducing the number of players able to be registered for European competition. PSG are already sounding off that they'll take UEFA through the courts, and there's also the possibility that a club such as Arsenal or Everton could take City through UEFA's own appeals procedure if their punishment is seen to be overly lenient.
This sounds a better option than fining mega rich owners.
So, if I understand, the guilty clubs could still sign players for domestic comps but these new players would not be able to be entered onto the European squad list for 2014-15? However the clubs could appeal through the courts but as this would take months the players would not be eligible for next seasons comps.
This would be a deterrent for any future,or present, rich corporation taking over a club and breaking the FFP rules.
How is the PL doing with it's policy of making all clubs "break even" at some future date? It's all gone quiet.
They could apply a similar rule that PL clubs would have no transfer ban but new players couldn't be registered to play until they complied with FFP or whatever rules the PL decide upon.
The guilty clubs could still compete in comps but would be penalised.
