All PSG has to do to compensate, is (in the case of Neymar) sell just for about as much as they have bought… and they have 3 years to do so. They can easily sell Verratti, Cavani and maybe one more dude and be well within the soft caps of that ruling. Mpappe makes it difficult tho, Mbappe and Neymar combined make it for 400M€. Last time PSG failed t obey fair play purchase they went to Champions League with 4 less players than everyone else and 8 of them had to be home-grown… they obviously did not learn.
HOWEVER I for one dislike the fair play rules quite a lot. While they prevent a billionaire owner from monopolyzing the football market and have international recognition; they also prevent small teams from splash transfers for their future if they can not possibly sell enough players for just about as much money as the one guy they buy. These rules advocate for status-quo, not for anti-monopoly; thus mantaining the big fishes big and literally creating a monopoly. I mean… it is not like that rule prevents PSG from regaining money from Neymar and Mbappe merchandise anyway. And if they are going to fine PSG, PSG can easily pay any ammount.
