"Sebastian and I have played alongside each other on many occasions for the Juve Primavera side, at Empoli and this summer as well with Italy," the midfielder said.
"He's come back here and slotted straight into the Coach's playing system.
"As for Pogba, he'll be an excellent player in the future. The boy has a lot of quality and he's come through a great academy like the one at Manchester United.
"He's got time on his side, he has to try and earn himself as much playing time as possible."
