The former Bianconeri boss has praised the signing of the forward and believes that the Serie A will finish with the Turin club on top again this season.
The Argentine striker joined Antonio Conte's side for an estimated 12 million euros earlier this month from Manchester City on a three-year deal and was given the No.10 shirt ahead of the new Serie A season.
Lippi, who took the Bianconeri to five league titles during his two spells at the Turin-based club, is convinced that the former Manchester United attacker will be a huge success in Italy.
"Tevez is a true warrior and, in my opinion, a great signing," the current Guangzhou Evergrande boss told La Stampa. "He's technically very good and has great character and will to fight."
The World Cup-winning trainer also expressed his opinion that Juve is the runaway favorite to claim glory in Serie A this season and praised Conte for the way he has adapted his ability to lead from playing into coaching.
"Juventus will win Serie A," he added. "I think the title is already theirs.
"Conte, as a captain, was a real leader, and he has clearly maintained that as a coach. I always knew he would become a good coach."
Despite putting faith in Conte's team's chances in Italy, the former Italy head coach believes that Real Madrid - under new trainer Carlo Ancelotti - will win the Champions League.
L"In Europe, I see the favorites as Real Madrid. I think Ancelotti is the right person for that team," he said.
