The Partenopei chief has commented on the challenge his side will face in beating the Bianconeri this season, but tipped them for a successful campaign
The Old Lady grabbed a controversial 1-0 win over Catania at the Angelo Massimino on Sunday, after which the losing side's president expressed his anger over Gonzalo Bergessio's disallowed strike.
"It will be hard if Juventus continue to win when they don't play very well," Bigon told Gazetta dello Sport.
"Referees said that every time you go away from the technical area you will be booked, but in Catania this situation was different."
Concerning his side's championship ambitions this season, the 41-year-old added: "We are sure that Napoli will fire until the end of the season for the first, second or third position."
Juventus, who face Bologna on Wednesday at home, are currently enjoying a three-point lead over Napoli in Serie A.
