The Ajaccio boss has nothing but praise for his former team-mate and has little doubt the successful coach will guide Juventus to victory over Lazio in the Supercoppa Italiana
Conte joined Juventus from Siena as coach in the summer of 2011 and has guided the Bianconeri to back-to-back Serie A titles since his arrival.
The Scudetto holders, who finished eighth in the International Champions Cup, are currently preparing for the Supercoppa Italiana match against Lazio, and Ravanelli has little doubt Conte and his men will emerge victorious.
"For me, Antonio is not just the best Italian coach, but he is the Messi of all coaches," Ravanelli was quoted as saying by Tuttosport.
"The Supercoppa might be worth more to Lazio than to Juventus, but I'm sure Conte will push all his players to the limit and beyond. That's probably his biggest strength.
"Juventus have the disadvantage that they have been working incredibly hard during pre-season, but Conte will never just give up on a trophy. I'm sure that he will get Juve there."
Ravanelli wore the Juventus jersey from 1992 until 1996, winning the Serie A title and the Champions League amongst other honours, during his spell with the Turin giants.
