The agent of Marco Verratti says the French media could drive him out of PSG.
Donato Di Campli has hit out after L'Equipe claimed that the player, along with Blaise Matuidi, partied in a nightclub two days before the 6-1 defeat by Barcelona.
"They should have to kiss his feet, if it happened again," he warned.
"It was absolutely crazy," he said of the story. "Pure invention. Talking about technical aspects is one thing, but here they have entered the private sphere of a player who has always kept a low profile."
Di Campli added: "We want a rectification but it has not arrived. We will file a compensation claim for damages.
"Verratti is not angry with the club and the fans, who have always behaved well. Marco has a contract until 2021.
"The president has reaffirmed his will to create a great team. But it's true too that my phone doesn't stop ringing. If anything like this happens again, we will have to think seriously."
