Ansaldi has been in Russia since 2008 and is still only 25 years old.
"He is an important player who is among the most reliable in that area of a team," agent Stefano Caira told Radio Crc.
"There is interest from Napoli, because they have made inquiries after my client. However, we have to wait and see what Rubin Kazan's intentions are.
"Unfortunately so far the price-tag has frightened off other clubs as well as Napoli. Ansaldi would gladly come to the San Paolo.
"Now the Partenopei are an important European club and, for a player with such clear Italian origins, it can't help but be a good solution for him."
