The 1970s saw the FA Cup won twice by Second Division clubs, the first time in the postwar era that the trophy had been won by a club outside the First Division. First, Sunderland lifted the trophy in 1973 at the expense of Leeds United. Three years later, Southampton defeated Manchester United to claim the first silverware of their history. In 1980, the trophy was won by a Second Division club for the third time in eight seasons when West Ham United triumphed over holders Arsenal.
