Walter Mazzarri won't risk Ezequiel Lavezzi, but warns Milan “something has changed” at Napoli after the Manchester City match.
The Partenopei welcome the Rossoneri on Sunday evening in what many are already calling the first Scudetto showdown of the season.
Lavezzi is a major doubt to feature, as he limped off with a heavily-bruised ankle during the 1-1 Champions League draw at Eastlands.
“We are waiting for the team doctor to give his opinion. In a game of this level, a player must be at his best in every area, both physical and psychological. Lavezzi wants to play, but we'll only field him if he is 100 per cent fit.”
Napoli impressed in their Champions League debut on Wednesday, as they very nearly beat Roberto Mancini's Manchester City.
“We have to play against Milan the same way we did in the second half in Manchester,” declared Mazzarri.
“Although I told the lads not to be too respectful or in awe of City, in the first half they were too tense.
“Clearly it was a great performance after the break. Against a top side we were able to play our football and impose our tempo. In Manchester we finally managed to have the attitude of a big club.
“We must stay humble, know our limitations, but at the same time never stop working to go past those limits.
“This is a different Napoli compared to last season. When we step on to the field, we have something more in terms of belief.”
