The French midfielder ended his time at Old Trafford to return to Juventus ahead of the next season.
Paul Pogba has opened up on his struggles for form and fitness during his time at Manchester United.
The Frenchman left Juventus to join United on an £89million deal in 2016.
However, his six-year spell at Old Trafford didn’t live up to expectations, convincing the Red Devils to part ways with him when his contract expired last month.
Pogba has now sealed a move back to Juventus, joining the Serie A giants on a free move. Speaking at his unveiling at the Allianz Stadium, the World Cup winner discussed his underwhelming spell at Old Trafford.
“Changing coach every year is hard. This was a difficult aspect for me,” he said.
“Then there were a few injuries, but I think it was also a mental thing; playing and not playing makes you lose the pace.
“There is a bit of everything; coach, team, position. All this has blocked me a bit.
“Now, however, I have left, and you will see another Paul. I can do better than I have in recent years.”
Pogba has won two of his four Serie A titles under Massimiliano Allegri. The 29-year-old says Allegri’s presence has been a key factor in persuading him to return to his old club.
He added: “Even in Manchester I often talked to him, we have always had a great relationship and even before coming here I talked to him.
“I spent many beautiful years with him, coming back here today means doing it at the right time and with the right person.”
