The Brazilian has been with the Turin-based team since 2015, and has won Serie A titles in each of his three seasons with the club.
Sandro has shone down the left flank for the 'Old Lady', but as he enters the last two years of his contract it is unclear whether his future still lies with the club.
According to 'Le 10 Sport', the player's represetatives and Juventus have not had any contact about prolonguing his stay with the Italian champions.
It seems as though PSG could take advantage of the situation to make an offer, with Alex Sandro knowing the French club's director of sport from his time at Porto.
A move to the French capital could see him pocket a significantly increased salary.
