Sutton United Football Club is an English football club currently playing in the Blue Square Bet South. They are based in Sutton, London, and play their home games at the Borough Sports Ground in Gander Green Lane.
The club started out playing in junior, local leagues, but progressed into the Athenian League in 1921; the Isthmian League in 1964; and the Conference in 1986. The team fell back into the Isthmian League in 1991. They appeared in the Conference for one more season in 1999–2000, and were founding members of the Conference South in 2004.
The team has had several cup successes, including getting to Wembley twice for the FA Amateur Cup final and once for the FA Trophy final. Sutton won the Anglo-Italian Cup in 1979. The club is most famous for its FA Cup exploits though, especially when they beat Coventry City in the Third Round in January 1989, the last time a non-League side beat a team from the top flight of English football.
