Spain's La Liga is challenging the legality of Kylian Mbappe's new contract, claiming Paris Saint-Germain breached financial fair play regulations to sabotage the World Cup winner's seemingly certain move to Real Madrid.
The Spanish league's lawyer, Juan Branco, announced this latest plan of action 48 hours after La Liga lodged a complaint to UEFA about PSG "continuously breaching the current regulations of financial fair play."
An identical complaint was lodged in April against another state-owned club, Manchester City.
Branco said France's sports minister would be their first port of call to try to get Mbappe's contract declared invalid.
If no joy there, they will ask the French league to seek an audit of PSG's accounts by French football's financial authority (DNCG), and then Paris' commercial court.
Branco said they were prepared to go to "the European Commission to ask them to intervene to even up the regulations."
That would trigger "a formal procedure for abuse of a dominant position," he said, adding their last resort was the European Court of Justice.
"It's clear to everybody PSG are acting outside the rules," Branco asserted.
He said La Liga's motivation for gunning for PSG and City was "to redefine the rules for a more virtuous ecosystem."
PSG are paying Mbappe a yearly salary of between €40 million and €50 million after the forward signed a new three-year contract.
PSG suffered a €224.3-million loss in 2020-21, an increase of 80 percent on the previous year, the DCNG detailed last month.
