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. Twenty-four people attended the meeting, including Cosme Damião, who would be the club's most important leader in its 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.
