The pair left Milan for PSG in the summer.
Verratti said: "Considering how talented Ibra is, he could just walk around and win games, but instead he works harder than anyone and only shouts at us for our own good. He is a leader and commands the team. It really helps you grow playing alongside him.
"We often talk about Serie A at PSG, as many of the team have been there. Ibra always tells me he was so happy at Milan. Both he and Thiago Silva say it is the perfect club. What is my perfect club? Pescara."
