Chelsea are eying the left-back as defensive cover ahead of their return to the Champions League, with Antonio Conte looking to add depth to his squad for the 2017/18 campaign.
The Blues have already had a £52m bid for the Brazilian rejected, and Express Sport understands an improved offer will be made in the coming days.
Chelsea could potentially double Sandro’s wages, but Juventus are reportedly set to offer the 26-year-old an improved deal in a last-ditch attempt to keep him at the club.
Blues fans are understandably frustrated with the complication, especially considering the Turin side bought Juan Cuadrado permanently last month and are also thought to be interested in Nemanja Matic – a potentially makeweight in a deal.
