LaLiga president Javier Tebas has taken fresh aim at PSG supremo Nasser Al-Khelaifi.
Tebas and the LaLiga have lodged a complaint to UEFA after Kylian Mbappe snubbed Real Madrid to re-sign for PSG.
And he was angered by comments made by Al-Khelaifi yesterday, when the PSG president said: "I don't give lessons to anyone or mess with other clubs or leagues. It is rude to pretend to tell others what to do.
"I do not accept lessons from those who see the Champions League as a threat to their league. I have a project to build, respecting everyone."
The president of LaLiga responded through social media: “The Al Khelaïfi thing is another level.
"He takes us all for fools."
And he added: "He gives lessons with the arrogance and arrogance of the nouveau riche. The rules exist for PSG. We will continue fighting for sustainable football without cheating."
