Jordi Alba has been the Spanish club's first-choice left-back for some time now, with Digne having made 19 appearances in all competitions for Barca this season, including Tuesday's 2-2 draw with Celta Vigo.
Both Barca and Digne are now ready to cut ties and bring an end to his time in Catalunya, and Juve have been informed by the player's agents that he may well be available in the coming transfer window.
A deal would make sense from the Serie A leader's point of view, with Juve lacking depth in defence, especially on the left-hand side where there are few options beyond first-choice Alex Sandro, who himself has long been linked with a departure.
Digne, who was capped at just 20 years old by France during the 2014 World Cup and has 21 international caps to his name, is seen as a player that would help Juve build on a season in which they are again likely to win the Serie A title.
The most likely transfer scenario would see Digne move to Turin in an initial loan deal, with the possibility of signing permanently for Juve at a later date.
Massimiliano Allegri's side could agree to a purchase option worth an estimated €25 million, allowing Barcelona to make a slim profit on the €20.5m including bonuses deal signed with PSG in 2016.
