Former Fiorentina coach Emiliano Mondonico is impressed by Vincenzo Montella's team.
Mondonico believes they can be title challengers this season.
"I think that Fiorentina are second only to Juventus,” he told TuttoMercatoWeb. “I can see a great rivalry forming between the Viola and the Bianconeri.
“But Napoli are also another team who have reinforced and will be near the top of the table."
