Aahead of the Italian side's second leg match with Real Madrid in the Champions League semi-finals, Pirlo revealed several things regarding the French star's arrival in Turin in 2012, including some rather disappointing news for those hoping Pogba will once again turn out in the red of Manchester United one day.
"I remember the players were almost in disbelief," Pirlo is quoted as saying in the Mirror. "We couldn't believe a club like Manchester United had let a player this good go. He has become the best young central midfield player in Europe, I am sure they regret it every day.
"Sir Alex Ferguson had so much success as Manchester United manager and made very few bad decisions, but letting Pogba leave was one of them."
The Italian legend thought the way Pogba was treated during his time as a Red Devil is enough to put him off considering the possibility of any return.
“He seems very happy at Juventus," added the 35-year-old in further quotes on Sky Sports. "I know he is focused on finishing the season with a lot of success. Whatever the future is for him I don't see it being Manchester United.
“He didn't feel he was treated well there. I know that was under Sir Alex Ferguson and now there is a new coach, but I do not seeing him returning to a club where he was not treated well.”
Things could get worse for United fans too. Late on Monday night, Pogba was said to be in talks with officials from Manchester City, according to Sky Sports.
City are one of only a few clubs who could afford the 22-year-old, though the likes of PSG, Barcelona, Real Madrid and United have also been credited with an interest.
If Pogba were to come back to Manchester, but not for the red of Old Trafford, it would make Sir Alex Ferguson's mistake even harder to stomach.
