Paris Saint-Germain may threaten UEFA with legal action over changes to financial fair play, according to Le Parisien.
Along with Manchester City, PSG were the club hardest hit when UEFA handed down its first swathe of FFP punishments last year, fining the Ligue 1 champions, limiting their Champions League squad size and tying their hands in the transfer market.
Though talks with UEFA are ongoing regarding their situation, PSG look likely to remain restricted in this summer's transfer window while City will have a free hand, contrary to reported assurances from UEFA that the two clubs would be treated in the same fashion.
Le Parisien reported on Thursday that PSG had already considered legal action last year, and could again ask their lawyers to explore the possibility of making a case against FFP, while the club's president, Nasser Al Khelaifi, has repeatedly demanded a review of the regulations to take into account the Premier League's massive new TV deal.
PSG's disillusion with UEFA's plans to stabilise European football's finances will only deepen, according to the outlet, with the possible introduction of a derogation for new club owners who wish to plough their massive fortunes into building a competitive side.
The paper claims to have seen documents which propose a four-year period in which owners who have just purchased a club will not have to meet FFP regulations, giving them time to sign the players they wish before they have to fall into line with their European rivals.
The reform of the FFP rules would be tailor-made for PSG's owners, Qatar Sports Investments (QSI), who have ploughed millions of euros into making the team a European heavyweight.
However, it will only apply for those buying a team from the 2015-16 season, meaning the original budgetary restrictions will apply to QSI.
