#7 David Beckham
A graduate of the glorious Class of '92, Beckham was possibly the best dead ball specialist in the world in his playing days.
When he scored a goal directly from a corner kick as a 19-year-old on loan for Preston North End, Sir Alex knew the lad was special. After being recalled in 1995, he made four league appearances for United that season.
Starting from the subsequent season, he was ever-present in the United squad, making at least 30 appearances each season before he left for Madrid in 2003.
He won 13 major trophies at the club, and perhaps the only blight on his near-impeccable record is his falling-out with Sir Alex.
Ferguson said in a 2007 interview that once he became a celebrity outside the footballing world, his playing career took a backseat.
But that still doesn't take away the fact that he was still one of the best players to have played under the Scot.
He provided a few memorable and spectacular moments in the United shirt, the most notable one being his thunderous strike from the halfway line against Wimbledon.
He is also the only player in the club's history to have worn both the number 10 and the number 7 shirts.
His subsequent moves away from United took him to Spain, Los Angeles, Milan and finally Paris. He also has 115 caps for England and captained the national side for six years.
