The midfielder followed Buffon from PSG to Juve this summer, but has battled for minutes so far this season.
However, Buffon insists: "It must be said that for ten months. Ten months, it's as if we had seen him twice, even if he trained ... He must return to the field, take his bearings, especially for someone with this great physique.
"You also change teammates, you come to Juve, a club with different working methods, you change a championship ... I think Adrien brings to Juve exceptional technical and physical qualities. It takes a period of adaptation for everyone. He will not be the first nor the last."
