Sir Alex Ferguson has revealed how Paul Pogba ended up leaving Manchester United.

In 'Leading' he expresses a dislike for agent Mino Raiola – Balotelli's representative who also oversaw Paul Pogba's departure from Manchester United.

France international midfielder Pogba subsequently shot to stardom with Juventus and is now one of the most coveted performers in the world game.

"There are one or two football agents I simply do not like and Mino Raiola is one of them," Ferguson said.

"We had Paul under a three-year contract and it had a one-year renewal option, which we were eager to sign. But Raiola suddenly appeared on the scene and our first meeting was a fiasco.

"He and I were like oil and water. From then on, our goose was cooked because Raiola had been able to ingratiate himself with Paul and his family and the player signed with Juventus."
