After four years in Turin, the France international decided to return to Old Trafford for a second spell in the summer of 2016.
The deal which took him back to England was the costliest in world football at the time, but the 25-year-old has struggled to justify that price tag amid constant criticism of his game and off-field activity.
Capello believes Juve have been the biggest benefactors of the lucrative transfer, with the trophies having continued to roll in for the Bianconeri while Pogba has been found out for United and France.
“That’s because with his physical strength, to us he seems impossible to control, but when he plays elsewhere, he becomes normal.
“I’d say Juventus got themselves a fantastic deal by selling him at that price.”
Pogba is currently in the process of trying to rediscover his spark while on international duty at World Cup 2018.
He has made a positive start in Russia, but one former team-mate has been denied the opportunity to grace such a stage.
Paulo Dybala starred for Juve in 2017-18, netting 26 times, but was overlooked by Argentina and Capello believes the 24-year-old is paying the price for a lack of consistency.
The Italian added: “Dybala is still a long way off [Lionel] Messi and Cristiano Ronaldo.
“He has to improve his consistency and the way he participates in the overall moves.
“He always waits for the ball to come to him, but that’s because he plays in a strong team that lets him do anything he wants.
“Dybala could’ve given Argentina something different, especially from distance, and I would’ve used him against Iceland.”
