The Juventus captain has praised his boss for bringing a winning mentality to Turin after the club had suffered a couple of years in the wilderness
The former Siena boss took the reins at the Turin giants in the summer of 2011 and has since delivered two successive Serie A titles and led the Old Lady to the Champions League quarter-finals.
“I think every coach has had a decisive impact on my career development but I have to say that Conte is definitely the best coach I’ve worked with," he told Fifa.com.
“In a short space of time he’s breathed new life into a team who in two seasons could do no better than seventh place. And he was a winner straightaway."
Buffon, who captains Italy as well as Juve, went on to say that Cesare Prandelli has revolutionised the Azzurri team since taking over in 2010.
"Thanks to the excellent job Cesare Prandelli is doing, I think we've found a balance between defensive solidity and an attacking approach that allows our great forwards to express themselves better," he added.
Prandelli led Italy to the Euro 2012 final in his first tournament in charge of his country.
