Milan is simply telling FFP to go fuck itself. They blatantly violate it, and once they manage to return to the CL, the punishment isnt remotely compared to the advantages of just breaking it
FFP made a complete joke of itself when City did the same thing, and they gave the insane radical punishment of "omfg one less player on your roster"
FFP is basically like buying SPAL 2013. Planting a 80k stadium. Buying Donnarumma, Alex Sandro, Bonucci, Chiellini, Carvahal, Verratti, Modric, Neymar, Messi, Ronaldo, Mbappe and 5 primavera kids
But FFP will strike you down with furious andger
1 less benchplayer in CL, THAT WILL TEACH EM
