Tottenham Hotspur have put a £20m asking price on Sandro's head in order to ward off interest from Napoli, according to the Daily Mail.
The 25-year-old Brazilian enforcer has been subject of ongoing interest from the Italian outfit, who are currently managed by former Liverpool and Chelsea boss, Rafa Benitez.
Sandro fell out of favour last term under Tim Sherwood, who deemed the Brazil international to be 'not good enough' to be selected towards the end of the campaign.
With Sherwood since sacked and replaced by Mauricio Pochettino, Sandro looks increasingly likely to remain at White Hart Lane next term, if Spurs can resist interest from Napoli.
The former Internacional midfielder has made 105 appearances for Spurs, scoring on three occasions.
