During his time at Manchester United, Rowley earned the nickname "The Gunner" due to his prolific goal-scoring abilities and powerful left-foot shot. He was a key member of the team managed by Matt Busby following World War II. Rowley played a significant role in the club's 1948 FA Cup victory and their 1951–52 First Division league title. According to official club records, he scored 211 goals in 424 appearances, making him one of the highest goal-scorers in the history of Manchester United.
At the international level, Rowley represented the England national team, earning six caps and scoring six goals between 1948 and 1952.
Following his playing career at Manchester United, Rowley transitioned into player-management, serving at Shrewsbury Town. He subsequently held managerial positions at several clubs, including Sheffield United, Oldham Athletic, and AFC Ajax in the Netherlands. Rowley retired from football management in the late 1960s and died in June 1998. His brother, Arthur Rowley, was also a notable professional footballer and holds the record for the most goals scored in the history of the English Football League.
