#2 Paul Pogba
Pogba would go on to become one of the best midfielders in the world at Juventus. Manchester United were very keen to get Pogba back. They eventually got their wish but it was an expensive deal as they had to spend £89 million to reacquire him.
Pogba had joined Manchester United in 2009 and made his Premier League debut in 2012. He did not get much playing time and was eventually sold off to Juventus. Juventus paid a mere £800,000 to acquire his services.
Pogba’s agent Mino Raiola was instrumental in Pogba's departure from Old Trafford. In Ferguson's autobiography, he talks about agents he does not like. As you can imagine Mino Raiola, Paul Pogba's agent finds himself on the list.
