Paul Pogba revisits his original departure from Manchester United to Juventus in his new documentary.

Pogba, aged 19 at the time, was struggling for first-team football under Sir Alex Ferguson but agent Mino Raiola, who had been involved in a bitter feud with the legendary United manager, demanded an improved contract.

Raiola, who passed away this year, says in the documentary: "I was in front of Ferguson, who I highly respect. There is a huge history of this club, but respect is something you give before you get it back.

"Ferguson thought we were exaggerating the value of Paul and we should have been happy to sign. I said for this money, my chihuahua would not walk on the grass off the training centre.

"I don't know if that's something the whole world needs to know."

In the film, Pogba also recalls the meeting.

"I was shocked," he says. "I was like, 'okay'. We got our stuff and he said 'we're leaving' and we left. Sir Alex, he'd probably never experienced anything like this in his career."
