Pogba, 25, returned to United in an £89m deal in the summer of 2016, having initially left the 20-time English champions to join Juventus on a free transfer in 2012.
The Frenchman played 178 times during his four seasons with the Italian champions - winning four Serie A titles and two Coppa Italia crowns in Turin.
Pogba struggled for consistency during the 2017-18 campaign, but the France international did finish the season with a respectable six goals and 12 assists in 37 appearances in all competitions.
The midfielder refused to commit to United when quizzed on his future earlier this week, however, and according to Tuttosport, Juventus are interested in re-signing the Frenchman this summer.
Pogba will represent France at the 2018 World Cup in Russia.
