The Supertaça Cândido de Oliveira (pronounced: [ˈsupɛɾ ˈtasɐ ˈkɐ̃didu dɨ oliˈvɐjɾɐ], English: Cândido de Oliveira Super Cup), also known as Portuguese Super Cup, is an annual Portuguese football trophy contested in a single match between the winners of the Primeira Liga and the winners of the Taça de Portugal. If a team achieves a double (Portuguese: dobradinha) of league and cup wins, it plays the runner-up team of the Taça de Portugal. Traditionally, the Super Cup is played just before the start of the next regular domestic season. The trophy is named after former player, coach and sports journalist Cândido de Oliveira.
The former trophy (left), handed to the winners since its inception, was replaced by a new one (right) since 2013.
In the 1943–44 season, the Super Cup was created for a special game between Primeira Divisão champions Sporting CP and Taça de Portugal winners Benfica, on occasion of the inauguration of the Estádio Nacional. The commissioned trophy was named Taça Império – not to be mistaken with Taça do Império, the first incarnation of the Taça de Portugal. After the game, it was decided that the competition was to be continued, but it was later canceled. The second incarnation came 20 years later when Casa da Imprensa (The Press House) instituted a trophy, the Taça de Ouro da Imprensa to be challenged between the national champions and the cup winners.
The Super Cup started unofficially in 1978–79 with a local derby between Boavista (Taça de Portugal holders) and Porto (league champions) that ended with a 2–1 victory for Boavista. The following season, another derby occurred between Benfica and Sporting, which constituted the second unofficial Super Cup and the first played over two legs (home and away). With the success of both unofficial Super Cup editions, the Portuguese Football Federation (FPF) decided to uphold the competition on a yearly basis in a two-legged format. The first official edition took place in the the 1980–81 season, already under the current name.
The rules stated that two matches were played and that the aggregate result would determine the winner. If a draw occurred, then a replay of the match should be played in a neutral ground. This occurred six times — 1984, 1991, 1993, 1994, 1995 and 2000 — with the replay of the 1984 edition being contested again in two legs.
Because interest in the Super Cup was waning and in order to reduce the crowded football calendar, in the 2000–01 season, the FPF decided to abolish the two-legged format and replay match and use a single match played in a neutral ground to determine the winner.
