The Bianconeri coach fears the Stadio San Paolo side will only become stronger team once the attacker is sold and feels Rafa Benitez was a shrewd appointment.
Juventus coach Antonio Conte believes that Napoli will be a stronger team without Edinson Cavani amid reports that the Uruguay international is on his way to Paris Saint-Germain.
The 26-year-old Cavani netted 29 goals in 34 Serie A appearances to help Napoli to second place in the table last term, yet Conte feels the Partenopei will only benefit from a potential summer transfer by being able to reinvest the huge sum it would receive the Uruguayan's services.
"I think PSG paying 63 million euros for Cavani is a gift to Napoli," Conte said at a press conference. "I would have preferred the 'Matador' to stay at Napoli. With him, we normally always beat them. Napoli will reinvest that 63 million.
"Moreover, now they have Rafa Benitez. He has won everything as a coach and for me is underrated."
Assessing the Bianconeri's other rivals ahead of the new season, Conte highlighted Inter, AC Milan and Fiorentina as the other major threats to his side's Scudetto crown.
"Inter have a great coach, and Milan only lost once in the second half of last season," Conte said. "Fiorentina are also becoming a great side with Mario Gomez coming in.
"The arrival of Rudi Garcia will help Roma. He did very well in France."
Juventus will be gunning for its third consecutive Serie A title this season after clinching the Scudetto both in 2012 and 2013.
