The France international left the Reds Devils on a free transfer to join Juve in the summer of 2012 after Ferguson refused to match the playmaker’s £20,000-a-week wage demands and guarantee the youngster regular first-team football.
He was the natural successor to Paul Scholes
The 20-year-old has blossomed at Juventus since his controversial move, helping the Turin outfit claim the Serie A title last season, whilst scoring five goals in 20 appearances this term.
And Pogba’s compatriot Zidane, who spent four seasons at Juve, felt Ferguson made a rare mistake when he failed to prevent the Frenchman leaving United.
Zidane told the Sunday Mirror: “The word ‘mistake’ is not something you would normally associate with Alex Ferguson’s time at Manchester United.
“But I do think it was a mistake letting Paul Pogba leave.
“He will go on to be one of the best central midfield players in Europe and he was the natural successor to Paul Scholes, someone they could have built the team around.”
“He is with Juventus and doing very well but, as always, Real Madrid will be looking to add the best players in the world,” Zidane added.
