At 6 in the countdown is a World Cup winner who spent his entire career at Elland Road.
Jack Charlton was certainly one of the most talented defenders of his generation, if not of all-time and was an integral part of the Leeds side that climbed the mountain from the Second Division and remained at the summit for several years.
Charlton began his career at Elland Road, joining the club in 1950 and making his debut three years later. The 1950s were an unspectacular time for the side, though they did enjoy promotion to the top flight in 1956. However, their stay in the First Division would span just four seasons.
It was Don Revie's appointment as manager in 1961 that saw the Whites' fortunes begin to head in one direction. While Revie often used Charlton up front - no doubt because of the height and physical presence he offered - it was the partnership the boss put together in central defence that was to prove crucial to the team's success for over a decade as he paired Charlton with Norman Hunter.
The duo helped Leeds secure promotion to the top flight once again in 1964. And once back at the top table, Leeds quickly became one of the powerhouses of the English game, winning two league titles, two Fairs Cups, one League Cup and one FA Cup, and coming close to winning more in almost every competition they competed in.
Charlton's presence was a key part of that trophy-laden period as the only medal he missed out on during those glory days was their second league crown in 1974 as he had retired one year previously.
Although the England international - who would be part of the World Cup winning side in 1966 playing alongside Bobby Moore in the final - spent most of his later career in defence, that did not mean that the decision to use him up front failed.
In fact, Charlton would score in 15 consecutive seasons and would finish his club career with 96 goals in total. He was also one of the first players to stand in front of the opposition goalkeeper at a corner.
Charlton made 773 appearances in total making him the club's all-time leading appearance maker. And while they would win the league title in the season following his retirement, his departure left a gap in the defence that has arguably never been filled.
