The failed attempts to reorganize
Club Lisbonense and Grupo Estrela paved the way for the appearance of the Club Internacional de Foot-Ball on 8 December 1902, which was the natural extension of the
Grupo dos Irmãos Pinto Basto () and the
Foot-Ball Club Swits. This is how in the first days of December 1902, a group of football enthusiasts gathered in a room at the Clube Naval Madeirense, deciding that the "Grupo dos Pinto Basto" would be reorganized and reinforced in order to make it stronger and thus be able to finish up with the power of the
Carcavelos Club. It was necessary, however, to give a name to the new Club. Due to the diversity of nationalities in the club's name, the idea of including the word International came up. Thus, the definitive name for Club Internacional de Foot-Ball was born, which was immediately liked, even because the acronym was small, suggestive and simple to fix "CIF". In a meeting held in Lisbon on late December 1902, the club's board of directors was established as follows: Commander Joaquim Costa as President of the General Assembly,
Carlos Villar as Portuguese Director, C. Bolt as English Director and Paulo de Almeida as
Treasurer. Fernando Pinto Basto was chosen as
captain, while
Eduardo Pinto Basto, W. Sissener and Abel Macedo were appointed to the Technical Council. The first headquarters of the Club Internacional de Foot-Ball was at Rua Pereira de Sousa, in
Campo de Ourique. Until then, correspondence was received at the club's treasurer's home and notices addressed to members and players were made through the daily press. ==Early success==
