#3 David Beckham

One of the most charismatic midfielders in English football, David Beckham spent 12 successful years at Old Trafford after his move from Brimsdown Rovers as a 16-year-old. Regarded by many as one of the best free-kick takers in world football, he was known for his long-range passing and crossing abilities.
Beckham's relationship with Sir Alex Ferguson deteriorated during the 2002/03 season and he was made to sit on the bench on few occasions. Manchester United wanted to sell him during the summer of 2003 and even agreed a deal with Barcelona. But the deal fell through as Beckham's only choice was Real Madrid and finally, he moved to the Bernabeu in a €35 million deal.
In an interview on BBC, Beckham said, "I had heard rumours I might be sold and one of my friends called and told me it was on Sky Sports that United had agreed terms with Barcelona. I then flew back to London and tried to speak to Peter Kenyon. He said it's true, we have agreed to a deal and that is when I spoke to my agent and said, if I am going to move, I'm going to move to Madrid"
