Lavezzi dreams of one day wearing the Napoli No 10 shirt which was retired in honour of former idol Diego Armando Maradona.
"Every Argentine wants to wear it," Alejandro Mazzoni told Radio Kiss Kiss Napoli on Monday.
"However, that is a decision that only Napoli President Aurelio De Laurentiis can take.
"One thing that is for sure, though, is that when Lavezzi played with the No 10 on his back he won the title with San Lorenzo."
The South American, who currently wears the No 22, has had a week to remember after goals against Milan and Brescia.
"He has matured greatly, he is serene and now a leader," Mazzoni continued. "Lavezzi has an excellent relationship with his teammates and the Coach, he'll have an important campaign.
"He's playing really well at the moment and scoring two consecutive goals is really important for him.
"The Scudetto? He certainly wants to win it with Napoli and when he plays he gives his all for the blue shirt."
