The former Pescara midfielder made the switch despite major interest from Juve.
"I chose to go to PSG, and I am very happy," Verratti told Sky Sport Italia. "I am happy with the choice, it is already bearing fruit.
"I do not think about what could have been. I am in Paris and I am happy to give my best to this club."
Verratti concluded by thanking former Juve man Zlatan Ibrahimovic for helping him settle into life at the Parc des Princes.
"I am happy with Zlatan's compliments. He helps me every day, giving lots of advice."
