Established in 2007, Portugese League Cup is an annual cup competition in Portugal where Primeira Liga and Segunda Liga teams compete for the trophy. All Segunda Liga teams face each other in round 1 (one leg), except for reserve or B teams.
First-round winners, 12 Primeira Liga sides ranked 5th-16th in the previous season and two sides who secured promotion from the Segunda Liga take part in the Portugese League Cup round 2.
Third round games are played in a single round-robin format, with each of the four groups containing three round 2 winners and one of the four highest-ranked Primeira Liga teams from the previous season.
Group winners advance to the knockout phase, where semi-finals games are played as one-legged fixtures. The title game is played in a neutral ground.
Benfica are the most successful club in the Portugese League Cup history, with the Lisbon Eagles winning their seventh trophy in 2016.
On August 7, 2011, Belenenses defeated Leixoes 5-3, which is considered the highest-scoring game in the history of the competition. On May 20, 2016, Benfica and Maritimo equalled the record as the Lisbon Eagles outclassed O Maior das Ilhas 6-2.
Benfica hold the record for the biggest win, with the team crushing Moreirense 6-1 in the Portugese League Cup round 3 on January 26, 2016.
Portugese League Cup season usually starts in late July and finishes in late January.
