Without question the most influential player in the long history of Manchester United, Sir Bobby Charlton stands atop the history books as the highest scoring player ever to wear the red shirt.
Serving as captain of the squad from 1966-73, his 249 goals remain well out in front of any remaining active player, meaning this record is most likely safe for some time.
He was also capped by England 106 times, scoring 49 goals, also a record that still stands.
United acquired Charlton while he was just a lad at the East Northumberland School, bringing him in to the system at a young age and then keeping him there until 1973.
Charlton himself acquired a number of honors in his time with United, including winning an FA Cup, a European Cup, three First Division Championships, four Community Shield's, and several other individual accolades including being included on multiple lists as one of the best players of the last century.
However, one additional honor that Charlton earned that nobody else on this list has: Charlton was part of the England squad that captured the World Cup in 1966.
He also won the Golden Ball in that tournament as the most valuable player.
Perhaps what makes his legendary status even more hallowed is the fact that he, along with Bill Foulkes, was one of the Munich Air Disaster survivors.
Even though United were able to sign him while he was still a non-professional, his transfer to the squad was the most influential in the history, as his play with United has been firmly cemented in the football history books.
