The 19-year-old only left Old Trafford during the summer on a free transfer for Italian champions Juventus.
However, rather than looking back, Pogba has revealed that his sole focus is on his new employers.
"I do not care, Manchester United is behind me. I'm happy to be at Juventus, I do not think at Manchester United," he told Italian media.
Pogba was talking after he had scored twice to help Juve overcome the challenge of Udinese 4-0 yesterday evening.
