Ian Callaghan was an immovable figure throughout the Reds' ascent from the Second Division to European champions, establishing himself as the club's record appearance holder in the process.
That figure - a quite remarkable 857 matches - is more than a century higher than his closest competitor, Jamie Carragher, and remains an achievement which is unlikely to ever be repeated.
'Cally' started his career as an energetic wide player with unerring accuracy when crossing from the flank; he made his debut in April 1960 and featured on 23 occasions as Bill Shankly's Liverpool gained promotion back to the top flight in 1961-62.
Two years later, the same team went one better by lifting the First Division title. The Toxteth native played in every single fixture. Always fit, always professional and always humble, a missed match was a rarity for Callaghan.
It was his pinpoint centre which landed on Ian St John's head and allowed the Scottish striker to win the FA Cup for Liverpool at Wembley in 1965, and the England international was ever-present once more as the championship was brought to Anfield again the following year.
Although the trophies dried up for the club towards the close of the 1960s, and Ian required a cartilage operation, the midfielder responded with maximum impact and adapted to a new central position in Shankly's team.
The 1970s proved to be a decade of unbridled success for Callaghan and his colleagues. He collected a third league winner's medal in 1972-73 - playing every match, naturally - plus the first of two UEFA Cup triumphs.
Ian was arguably an even more accomplished performer in his new role, with the Englishman's work-rate and knowledge of the game aiding the transition from Shankly to Bob Paisley and maintaining the procession of silverware into the Anfield trophy cabinet.
Having started life at Liverpool outside England's top division, Callaghan was in the starting line-up in Rome when the Reds were crowned as the continent's best after beating Borussia Monchengladbach in 1977.
The midfielder played his part as the trophy was retained 12 months later and, after making his 857th and final appearance for the club in April of that year, one of the most glorious relationships between the Kop and a player concluded.
