Big deal: Nani's Juve move depends on his recovery from current injury
The Manchester United attacker has a hamstring injury that will keep him out into the new year.
But the Italian giants are hoping Nani recovers quickly after being encouraged that United boss David Moyes will sell the erratic Portuguese.
Nani, 27, surprisingly penned a new five-year contract at the Old Trafford giants in September – but it is thought that was to ensure a healthy transfer fee.
Signed from Sporting Lisbon in a £22m deal in 2007, Nani has failed to fully ignite his Old Trafford career after appearing to initially step up following the departure of Cristiano Ronaldo.
The transfer window opens next month with Moyes ready to let Nani go. United would ideally like a swap with their former French international midfielder Paul Pogba – but Moyes accepts that Juventus are unlikely to agree to that.
