Futebol365 say that the Italian champions are planning a move in the winter transfer window for the Portugal international.
Talks over a new contract have so far stalled between United and Nani's camp, so a move to Serie A with the Italian giants Juventus is an option at this point.
Juve with be hopeful of landing the winger for considerably less than the £20m Manchester United paid for him five years ago.
