Maurizio Zamparini revealed that Balzaretti finds the prospect of moving to the Italian capital "fantastic", but that Roma must improve their bid for the 30-year-old to £4 million if they want the full-back.
“The interest from Roma is the most intense,” Zamparini told Radio Radio.
“Recently Juventus also stepped forward, but we’ll see what happens. Federico told me if he had to choose a city to live in, then Rome would be fantastic.
“However, Roma have to improve their offer and at least match that of Napoli. That means reaching €5m cash with no player exchanges involved.
“We can take several options into consideration, such as a paid loan or a permanent transfer with payments spread out.”
