PSG sponsors have already been regulated. QTA, the infamous contract, doesn't exist anymore. As a consequence, we aren't doing our usual winter trip to Qatar. We are promoting Rwanda now, like Arsenal, and getting 10/20 M€ per year. PSG recently signed with Qatar Airways for around 7/15 ME per year, following the standard prices in european football. You just need to check. UEFA can not lower anything anymore as it is in the fair market value.
De Jong didn't exactly refused PSG because of French League. He was seconds away to sign for PSG until Barça made a last minute push. And Barça is his favorite club. So, PSG was seen as the most attractive proposition for a very long time, even ahead of rich PL teams like City.
De Ligt was reportedly seen visiting appartments in Paris with his gf and Raiola came discuss his transfer in Paris but Juventus came in with a better proposition and agreed to put a release clause in the contract. Same story happened with Haaland. Seems like Raiola is adamant in putting release clauses in his most valuable clients contracts, prolly angry about Pogba not being able to leave United.
If those are the two examples PSG is not attractive for the top young players, i'm not too worried. They considered us more than all the PL teams after them.
