A week after the final, on 26 April 1960, he was signed by Manchester United for £5,000 as cover for Noel Cantwell and Shay Brennan. His debut for United came against Burnley on 15 October 1960, playing at left-back alongside Maurice Setters. He helped Manchester United win the FA Cup in 1963, and the First Division title 1965 and 1967. His highest honour came as part of the side that won the 1968 European Cup, beating Benfica 4–1 in the final. This was despite having ruptured his Achilles tendon in the quarter-final of the competition against Gornik Zabrze.
