LaLiga president Javier Tebas has accused Paris Saint-Germain of deceiving Financial Fair Player rules and claims he has proof.
The French giants were once again busy in the transfer market after signing five new players in the latest window, including former LaLiga stars Lionel Messi and Sergio Ramos.
PSG also managed to tie Neymar down to a new contract to go along with the big wages for their new signings, but Tebas is not convinced the club are moving within the rules.
"I criticise PSG because it does not generate the money to have the squad it has," Tebas told L'Equipe.
"This causes a distortion of competition in the European football economy. It does not correspond to actual sponsorship.
"How can PSG explain to us that it has a squad of almost €600 million? If you win Ligue 1, you won't win more than €45m – it's impossible.
"I invited the president of PSG and the president of the French league to show them the numbers we have and where the irregularities are. They did not answer me. They are quick to criticise me, not answer me.
"I can show, with figures to back it up, the deception in the face of Financial Fair Play. If Messi and Neymar remain at PSG, I don't care. The point is that all this hurts European football a lot. I'm not the only one who says it."
