The Frenchman was seen as one of the brightest talents to come through the Red Devils' academy in years, but elected to move to Serie A in 2012 due to a lack of opportunities

"I said to Ferguson: 'Play me, and I will show you if I'm ready or not'," he told Telefoot. "Against Blackburn, on December 31, 2011, I was on the bench. Ferguson puts Rafael in midfield with Ji Sung Park. Then I gave up. I was really bummed.
"I joined Juve to silence people who have criticised me, who did not believe in me and said that I would fail."
Ferguson claimed at the time that the young midfielder had shown a lack of respect in the way he and his agent, Mino Raiola, had agreed a deal with the Bianconeri behind United's back.
Since then, Pogba has become a key component of Antonio Conte's Juventus side, and cemented his reputation as one of the best young players in the world by winning the Golden Ball for his performances for France at this summer's Under-20 World Cup.
Goal understands that United, cautioned by their experience with Pogba, are preparing an unprecedented contract offer for young Belgian Adnan Januzaj, whose contract expires at the end of this season.
