Manchester United legend Rio Ferdinand claims former manager Sir Alex Ferguson was wrong in letting Paul Pogba leave Old Trafford. He left the Red Devils as a free agent and completed a move to Juventus in 2012.

Since joining the Italian club, the France international has won the league every season and was a part of the squad that lost to Barcelona in the Champions League final in 2014 May. His form has seen him attract interest from top clubs across Europe.

Pogba was linked with a move to Chelsea in the summer, which was dismissed by Blues manager Jose Mourinho. The 22-year-old admitted the time was not right for him to leave the Turin club.

The former United defender believes the Juventus star is a potential Ballon d'Or winner in the future. Ferdinand has also backed Pogba to become the best midfielder in the world in the next three to four years.

"Potentially, Pogba can be a Ballon d'or winner," Ferdinand told BT Sport, as quoted by the Daily Mail.

"I asked him. 'Why are you going? Where are you going? You're going to Juventus. That's not as good a league as the Premier League. You're at Manchester United. Where are you going? What are you doing?'

"He looked at me deadpan and went: 'I want to be the best player in the world and I'm not playing. I want to go and play.'

"I do, but that's with hindsight. Sir Alex Ferguson would say the same thing. I think he has the personality to be the best. I think Pogba really will go on to be the best player in the world in the next three or four years. He's got that personality. That desire to be the best player."

"The way he trains, the way he looks at his game. He believes in himself like not many other players I've seen," he added.
