Former Napoli goalkeeper Luca Bucci has urged the club to stick with coach Roberto Donadoni.
He said: "It's premature to speak of change, but perhaps it also comes from the end of last season, even though I believe everything is reset with a new season.
"Donadoni is a good coach and is trying to make the team play well, but I do not understand why the team cannot play with continuity over the 90 minutes. I would not change, in football you have to have patience."
