With Spurs, he won the UEFA Cup in 1984 and the FA Cup in 1991 (as captain). In the 1987 FA Cup Final against Coventry City, Mabbutt had an eventful game where he scored Spurs' second goal to put them 2–1 up but, after Coventry had equalised to force extra time, he scored an own goal to give Coventry a 3–2 win. This incident led to him being held as something of a folk hero at Coventry City, with a fanzine being named "Gary Mabbutt's Knee".
