In this tournament, they hold the overall record for the biggest aggregate win, achieved in 1965–66. On 28 February 1904, the group and members of Associação do Bem met at the back of Farmácia Franco on "Rua de Belém" with the goal of forming a social and cultural football club called "Sport Lisboa", composed of Portuguese players only. 24 people attended the meeting, including Cosme Damião, who would be the club's most important leader in the first decades. In that meeting, José Rosa Rodrigues was appointed club president, along with Daniel Brito as secretary and Manuel Gourlade as treasurer. The founders decided that the club's colours would be red and white and that the crest would be composed of an eagle, the motto ""E pluribus unum"" and a football. Sport Lisboa played their first match ever on 1 January 1905, scoring their first goal. Despite important victories, the club suffered from poor operating conditions, namely the football dirt field Terras do Desembargador. As a result, eight players moved to Sporting CP in 1907, starting the rivalry between the two clubs. On 13 September 1908, Sport Lisboa acquired Grupo Sport Benfica by mutual agreement and changed its name to "Sport Lisboa e Benfica". Despite the club merger, they continued their respective club operations. For Sport Lisboa, they maintained the football team, the shirt colours, the eagle symbol and the motto. For Grupo Sport Benfica, they maintained the field Campo da Feiteira, the main directors and the club's house. Both clubs determined that the foundation date should coincide with Sport Lisboa's because it was the most recognised club and quite popular in Lisbon due to its football merits. In regard to the crest, a cycling wheel was added to Sport Lisboa's to represent the most important sport of Grupo Sport Benfica. Furthermore, the two entities of the "new" club had simultaneous members who helped stabilise operations, which later increased the success of the merger. However, problems with the club's rented field (Campo da Feiteira) remained. Benfica moved to their first football grass field, Campo de Sete Rios, in 1913. Four years later, after refusing an increase in rent, they relocated to Campo de Benfica. Finally, in 1925, they moved to their own stadium, the Estádio das Amoreiras, playing there fifteen years before moving to the Estádio do Campo Grande in 1940.
