Verratti has been linked with Juventus.
"Which Italian club has 25m for Verratti?" Donato Di Campli asked Rai Sport 1. "He's wanted by a number of sides now, we are talking about the biggest clubs in the world.
"However, I've already met with PSG sporting director Leonardo and we'll meet again at the end of the season to discuss an improved contract. I don't anticipate problems on that front.
"Marco is really happy to be at such a great club. The enthusiasm in Paris is crazy and the project is very important."
