PSG are also under investigation by UEFA for violating the Financial Fair Play policy and if there is no retribution for that then it gives almost every club the permission to do the same. UEFA must be firm and act upon it even it means they are disqualified from further competition.
Financial Fair Play is a myth, Man City & PSG continue to get away with spending far more than they generate which is the whole point. They lie about their books/records & all they get is a slap on the wrist from UEFA or a minuscule fine. These teams wont take it seriously unless they get banned from the CL for a season or two.
