The midfielder struggled to make the first team at White Hart Lane during Tim Sherwood's reign at the club, resulting in him being linked with moves to a number of Serie A sides.
Luiz Paulo Chignall told calciomercato.com: "The interest of Napoli and Roma? We have not had direct contacts and there have been no formal offers. We know that many clubs are following Sandro.
"He would like to play in Serie A, it is a very important championship but now we have to wait to know if he can leave Tottenham or not.
"He is very fine in London and has a great relationship with the fans, who consider him an idol. I think that Tottenham want to keep him, but I cannot rule out that they decide to sell if there will be a good offer."
Sandro made 18 appearances for Spurs in the 2013-14 season, scoring once.
