The Italian midfielder's representative claims that the Ligue 1 winners will offer his client an improved contract in a bid to curtail interest from Real Madrid
The 20-year-old enjoyed an impressive debut season in the French capital last term, making a total of 27 league appearances and setting up four goals in the process.
The Italy international has been widely linked with a move to the Santiago Bernabeu this summer but the Ligue 1 champions are determined to make him stay put.
"He's happy with PSG and will meet the company next week to talk about his future and request an adjustment," Donato Di Campli told Mediaset on Thursday.
"There is interest from Madrid in the boy. I read a lot of newspapers and I am very pleased that Marco is being sought by big clubs like Real Madrid."
PSG spent €12 million (£10.2m) to bring Verratti to Parc des Princes from Pescara in the summer of 2012.
