Sagna fell out of contract at Manchester City at the end of last season and remains without a club.
The 34-year-old Frenchman says Inter were interested in his services in 2014 but at the time he wanted to continue his career in the Premier League, but now a move to Italy appeals.
“I've heard about the Nerazzurri several times, especially during the summer that I went to City from Arsenal,” he told Gazzetta dello Sport.
“At the time, I wanted a new adventure in the Premier League. That’s why I didn’t go to Milan.
“Future in Italy? Yes, I’m ready for it. I follow Serie A a lot and there are other big teams like Napoli, Roma, Milan and Juve.
“It’s a competitive league and a challenge that I’d jump at taking.”
