The 36-year-old has little doubt that the former Athletic star will prove to be a good signing for the Scudetto holders
The Spanish attacker has been struggling to live up to the high expectations since his summer move from Athletic Bilbao and has mainly been forced to watch from the sidelines.
However, Toni has little doubt that Llorente will become a valuable first team member at Juventus once he has adapted to his new surroundings.
"Llorente has always done well in La Liga and with Spain's national team. Juventus signed him because they think he can add something. It's way too soon to write him off," Toni told Tuttosport.
"At the moment, it seems as if Conte prefers attackers with different characteristics than Llorente. He prefers attackers who combine well, help each other and can add something outside the box, too.
"That being said, I am convinced that Juventus will spend a lot of time in their opponents' area and Llorente will prove to be useful."
Llorente has made just one official appearance for the Serie A champions so far.
