George Best, Denis Law and Bobby Charlton terrorised defences all over Europe for the best part of a decade. And yet the United Trinity was only two when the Reds won the European Cup in 1968.
Injury meant Denis Law had to watch the match from his hospital bed as he recuperated from a cartilage operation. What he witnessed, however, was one of the most emotional occasions in the club's history.
Ten years after eight of his players and three club officials perished in the Munich air disaster, an emotional Sir Matt Busby watched as Charlton, a fellow crash survivor, lifted the cup after a thrilling extra-time victory over Benfica at Wembley Stadium.
Charlton opened and, later, closed the scoring, breaking the deadlock eight minutes into the second period with a deft header. United had chances to put the game to bed but with nine minutes left Graca equalised for Benfica.
Benfica could have won it when Eusebio had only Alex Stepney to beat but he hammered his finish straight at the keeper and the final went into extra-time. For the next nine minutes, United cut loose. Best nutmegged his marker and, with a trademark hip shimmy, rounded Henrique to nonchalantly side-foot home. Brian Kidd then capped his 19th birthday by scoring the Reds' third goal and setting up Charlton to make it 4-1.
