Miller signed for Aberdeen in 1972 at the age of seventeen and was made captain four years later by manager Ally McLeod. His central defensive partnership with Alex McLeish was integral to Aberdeen's success in the 1980s, as they won all the major domestic honours and the European Cup Winners' Cup in 1983. He retired from playing in 1990 due to an injury picked up whilst playing for Scotland. In 2003, Willie Miller was voted the greatest Aberdeen player of all time in a poll to mark the club's centenary.
