The winger has been a target for Napoli since January.
“From what I know, his agent has said yes to the transfer," Gazzoni Frascara told Radio Kiss Kiss Napoli.
“Verdi might not be world class, but he is a very good player and can give Napoli a hand. I really wasn't expecting them to hire Carlo Ancelotti, but it was a great coup from President Aurelio De Laurentiis."
A five-year contract with option for a sixth season should be signed over the next few days.
