The 32-year-old Frenchman is due to be a free agent at the end of the season.
While Evra has held talks with United over a new deal, Federico Pastorello suggests that the full-back is interested in the Italian top flight after spending the early part of his career with lower-league sides Marsala and Monza.
"Patrice has to decide what to do with his future," he told Tele Radio Stereo. "He is very close to United, but lately things have changed a little.
"Could he come back to Italy? Patrice has always highly regarded Serie A and so, if he were to leave England, it could be a possibility. But at the moment it is still too early to talk about next season."
Evra joined United from Monaco in 2006.
