Despite United's midfield being depleted through injury, Pogba could only earn a place on the bench at Ewood Park after then manager Ferguson selected right-back Rafael, and the Frenchman says that was the catalyst for him to seek a move elsewhere.
The 20-year-old told Telefoot: "I said to Ferguson: 'Play me, and I will show you if I'm ready or not'.
"Against Blackburn on December 31, 2011, I was on the bench. Ferguson puts Rafael in midfield with Park Ji-Sung. 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."
Pogba has since established himself in Serie A, making 40 appearances at the Italian club.
