Best made his First Division debut, aged 17, on 14 September 1963 against West Bromwich Albion at Old Trafford in a 1–0 victory. He then dropped back into the reserves, before scoring his first goal for the first team in his second appearance in a 5–1 win over Burnley on 28 December. Manager Matt Busby then kept Best in the team, and by the end of the 1963–64 season, he had made 26 appearances, scoring six goals. Manchester United finished second, four points behind Liverpool. They also reached the semi-finals of the FA Cup, where a defeat to West Ham United cost Best the chance to break a record; in the final Preston North End's Howard Kendall became the youngest ever player in a FA Cup Final – he shared the same birth date as Best. That same season, Best captained the Manchester United side that won the 1964 FA Youth Cup, the sixth FA Youth Cup won under the management of Jimmy Murphy, and the first since the 1958 Munich air disaster.
