Enzo Maresca is confident Napoli can mount a successful title defence under new coach Rudi Garcia.
Napoli have had an inconsistent start to the season.
But Leicester City manager Maresca told Il Mattino: "Yes, but watch out for the old adage: winning is difficult and 'winning again' is even more difficult. The Azzurri, however, they remain one of the candidates for the tricolor together with Inter and Milan.
"Could some players have a full belly? I agree if we speak for those who have won a lot. But in the case of Napoli I don't think the boys are already satisfied. In fact, I don't see it as a danger at all.
"Garcia? If the choice fell on him, it means that he was considered up to the task by (Aurelio) De Laurentiis' club. It is clear that he will need time to make himself known. Logically it is not easy to replace (Luciano) Spalletti for what he has done. Also because people don't forget and they make comparisons at the first wrong opportunity."
