The 27-year-old has been limited to only eight appearances across all competitions this season, the most recent of which came on Boxing Day.
Recent reports have suggested that Juventus are now leading Real Madrid in the race for Pogba and are willing to offer players as makeweights in any attempt to bring their former player back to Turin.
Here, Sports Mole looks at which numbers could be available to the World Cup winner at Juventus.
Pogba's number of choice could be very straightforward if he does make the move back to Turin, with the Frenchman having worn the number six throughout his time at Manchester United and for much of his Juventus career too.
That number is currently taken by Sami Khedira, but the German's own future is also in doubt with just one more year remaining on his contract.
Should Khedira leave the club then Pogba would be a clear choice to inherit the number six, but if he remains then the United man may be forced to settle for a new number.
Pogba did wear the number 10 in his final season at Juventus and that could be another option should he return, although Paulo Dybala is the current occupant and is unlikely to be usurped unless he leaves the club.
The only other number Pogba has worn during his club career is the '42' during his early United years and that is currently vacant at the Allianz Stadium, although it is unlikely that he would sink so low down the ranks considering his status now.
Other options include '15' and '20', both of which he has worn for France before and are unoccupied at Juventus as things stand - so too, incidentally, is the number nine shirt.
