The experienced goalkeeper feels the Montenegro star would help the Serie A champion close the gap to the likes of Bayern Munich.
The Montenegro international has long been linked with a move to the Serie A champion, although the club faces stiff competition from the likes of Arsenal, and Buffon believes Jovetic would be an excellent signing as the Bianconeri look to compete with the likes of Bayern Munich in Europe next season.
"Jovetic? Any player who will help Juventus improve is more than welcome, except a goalkeeper of course...," Buffon told Tuttosport. "We must follow the path we are on and try to improve on our performances from the past few seasons.
"It will not be easy to close the gap with the European top clubs, of which Bayern Munich has impressed me the most. But Italian football has plenty of young talents, both at Juventus and at other clubs. I believe in Juventus' management and don't fear the departure of any champions."
The 23-year-old Jovetic has a contract with Fiorentina until June 2016, but could be available for a fee in the region of 25-30 million euros.
