The 19-year-old Frenchman, who has made seven appearances from the bench at Old Trafford this season, has been repeatedly linked with a move to Serie A leaders Juventus.
"[Pogba] can remain at Manchester United or go to Juventus," Mino Raiola told Sky Sport Italia. "It's a tough decision to be taken by the boy, thinking of his career. Both possibilities present some chances.
"United count on him and want to extend his contract. His future will depend very much on the will of the boy."
Pogba signed his first professional contract at Old Trafford in 2011 after two years in the club's youth system.
