Now every Spanish newspaper reports about this: Barca will denounce PSG to UEFA. Tebas will file complain independent from Barca(probably hated the fact that Barca is getting 220M cash). PSG has to bring 110M sales from the players by January 2018(which means blowout sales on certain PSG players,"everything must go type of deal").
What Tebas should do in first place is to make obligatory buyout clauses go away.
Not only becaue of Neymar's transfer but mostly because PL teams have stolen a lot of young talent from La Liga clubs (not only Barça) because of those stupid clauses which are usually set low and are in somewhat correlation with player's wages. Not always of course but clubs like Gijon or Betis who don't pay high wages can't really set those clauses on 50M or higher to keep potential suitors away. Let clubs alone decide if, when and for what money they are willing to let their players go. Smaller teams would keep their best/most talented players for longer time and/or get more money than they do now and league would become more competitive.
For Barça it would also be a good thing as we'd probably be able to keep more of our youngsters and on the other hand we never really use low buyout clauses to get talented Spanish players like Asenjo, Ceballos, Fornals,... and there is no indication we'll start doing that in near future as much as I'd like for us to also profite sometimes from those rules. But we'll probably only start to use that approach a year or two before they'll cancel obligatory buyout clauses.
