Pogba, 19, was playing for Le Havre in France when Ferguson and United moved to snap him up in 2009.
However, despite his enormous potential, Pogba made only seven appearances in two seasons for the United first team after his graduation from the Old Trafford academy.
Pogba has since gone to become a mainstay of the Juventus first team under the tutelage of coach Antonio Conte, scoring four times in 18 appearances for the Turin side.
The France Youth international was already making a name for himself with Juve when Udinese arrived at the Juventus Stadium at the weekend, but his first goal in the 4-0 victory has the mark of a champion.
After the win, which extended Juventus' lead at the top of Serie A to five points, Pogba told Raisport (reported to Sky Sports) that he had no regrets about leaving Old Trafford.
Ferguson will be watching his protege's progress with interest, but holding their own significant lead in the Premier League and a Champions League tie against Real Madrid on the horizon, there will be little concern over the loss of Pogba for the United manager.
However, the emergence of Pogba as a major talent on the European scene may act as a catalyst of some doubt for United supporters looking to the future.
Pogba was considered to be a versatile squad member at Old Trafford, equally comfortable in defense and attack. For a man of stature (Pogba is roughly 6'2"), he possesses tremendous ball control and has supreme confidence in his ability.
He can dominate midfield and has the ability to select the right passes at the right time for teammates. As witnessed against Udinese, he also has a fearsome drive from distance on him. Pogba lacks fear, but does have intelligence and calmness on the ball.
There are few weaknesses in his game, and although some United supporters would highlight his positional sense, his exceptional skills on the ball can atone for that.
Pogba still has a long way to go in terms of proving himself. His current form needs to be consistent across his career before he can be considered great. In the days of hyper-communication, a young player like Pogba can be overrated on the back of a few great displays. The jury will remain out for the time being.
Nobody, however, should bet against a Champions League collision between Ferguson and Pogba in the very near future.
