The Juventus skipper says the young Frenchman has made a great impact in Turin but feels the midfielder still has some growing up to do.
The midfielder arrived in Turin last summer from Manchester United and made 28 Serie A appearances, scoring five goals in the process, and the Bianconeri skipper has been pleasantly surprised by his teammate's impact.
"You have to say that he's been a big and great surprise because we didn't know how strong he could be when he arrived," Buffon told RMC. "He's shown on the pitch that he can be very strong and we have got to know him. He's an exceptional kid, very humble.
"He still has problems with punctuality but that's normal because he needs to become more mature. But I'm certain that he will leave his mark on the history of Juventus and the France national team."
Buffon and Pogba helped the Old Lady retain their Serie A title, finishing nine-points clear of Napoli in second.
