That"s according to Transfer Market Web, who claim Manchester City and Paris St-Germain are still going after the 26-year-old too.
Sandro has cemented his place as one of European football"s top attack-minded full-backs during his two-season spell with Juventus.

And it seems his performances in Turin have caught the eye of a trio of top bosses as they plan for the 2017/18 campaign.
Antonio Conte, Pepe Guardiola and Unai Emery have been backed to make moves for Sandro before the transfer window shuts.
And Transfer Market Web reckon all three could yet swoop for him.
They claim Chelsea have seen a £50m (€56m) bid rejected already.
And they indicate Conte is poised to return with a fresh offer.
Guardiola and Emery are apparently monitoring Sandro"s situation too.
And that"s despite the City boss spending £52m on fellow left-back Benjamin Mendy this week.
Serie A champions Juventus are determined to keep hold of Sandro though.
And the fact he"s under contract until 2020 means they are under no pressure to sell.
