Facchetti spent his entire professional career with Inter, later captaining the side, after Armando Picchi, Mario Corso, and Sandro Mazzola, during his final season with the club, between 1977–78. With his club, Facchetti won four scudetti in 1963, 1965, 1966 and 1971; one Italian Cup in 1978; two European Cups in 1964 and 1965; and two Intercontinental Cups in 1964 and 1965. Due to his performances for Inter, Facchetti also narrowly missed the opportunity to become the first defender to win the Ballon d'Or, placing second in 1965, after narrowly missing out on a treble winning season with Inter that year; Inter won the Serie A and the European Cup, but were defeated in the 1965 Coppa Italia final by Juventus. Facchetti's 59 goals in Serie A make him the most prolific defender in the history of the Italian league.
