The 1991 Supertaça Cândido de Oliveira was the 13th edition of the
Supertaça Cândido de Oliveira, the annual
Portuguesefootball season-opening match contested by the winners of the previous season's top
league and
cup competitions (or cup runner-up in case the league- and cup-winning club is the same). The 1991 Supertaça Cândido de Oliveira was contested over two legs, and opposed
Benfica and
Porto of the
Primeira Liga. Benfica qualified for the SuperCup by winning the
1990–91 Primeira Divisão, whilst Porto qualified for the Supertaça by winning the
1990–91 Taça de Portugal.[3][4]
The first leg which took place at the
Estádio da Luz, saw Benfica defeat Porto 2–1 as a result of a late
William goal. The second leg which took place at the
Estádio das Antas saw Porto defeat Benfica 1–0 (2–2 on aggregate), which led to the Supertaça being replayed in September 1992. The replay which took place at
Estádio Municipal de Coimbra, saw Porto defeat Benfica 4–3 on
penalties which would claim Porto a sixth Supertaça.[5]
