 John spent six seasons at Liverpool without really setting Anfield alight, he was a consistent, tough tackling, uncompromising full-back who made a wingers job even more difficult than it already was, but during the club's promotion season of 1961–62 he was a peripheral figure playing just 3 league games and 1 cup match, this was mainly due to the phenomenal full-back partnership developed by Gerry Byrne and Ronnie Moran.Bill Shankly then decided that John was no longer a part of his plans and was allowed to leave in the August 1962 after clocking up 249 appearances.Molyneux rejoined former club Chester, where he played for two more years before dropping into non-league football with New Brighton.
