During this period, the team picked up the affectionate nickname the Busby Babes, because of the youthfulness of many of the players he fielded. They won the league in both 1956 and 1957, and were runners-up to Aston Villa in the 1957 FA Cup Final. The young side was so successful that centre-forward Tommy Taylor and goalkeeper Harry Gregg were United's only major signings over a spell of almost five years.
