At 15 in the countdown is a defender whose goal secured Leeds' first major trophy under Don Revie.
Terry Cooper's time at Leeds United spanned almost the full length of Don Revie's tenure as manager at Elland Road. And while injuries would blight the left-back's later career at the club, his performances for around six years were a key reason why the team enjoyed as much success as they did at that time.
Although he began his career at the club as a winger, Revie soon moved him to the left-hand side of defence. There, he formed a wonderful partnership with Eddie Gray who usually played in front of him on the flank. Cooper's willingness to get forward meant that defenders had plenty to think about, but they often had little reply for his overlapping runs.
The defender would cement his name in Leeds history by scoring the goal that won the Whites the League Cup in 1968. It was his volley that gave them a 1-0 victory over Arsenal and secured the club's first major trophy since Revie had taken charge of the team.
He would also be a key member of the side for their Fairs Cup win later that same year, starting both legs of the final against Ferencvaros.
The next season was even more successful for the club as they won the First Division title, finishing the campaign six points ahead of Liverpool.
His performances for Leeds saw him brought into the England set-up, and he went on to become their first-choice left-back for the 1970 World Cup.
And while he would help United win the Fairs Cup again in 1971 - once again, starting both legs as the Yorkshire side beat Juventus - the 1971-72 season was to prove to be a crucial one in Cooper's career for the wrong reasons.
A leg break in the latter stages of the season meant that he missed the FA Cup final victory over Arsenal, and would sit out the next campaign, as well as the majority of the one after which saw Leeds go on to win the league.
By the time he had returned, injuries had taken their toll on him and he was unable to break back into the side, though he continued to play for nine years following his departure for Middlesbrough in 1975.
Cooper's best days at Elland Road coincided with much of the time when the club was at its strongest. And as with most of the players in the great team that Revie assembled, he was just as important as any other piece in the jigsaw.
