On 13 September 1908, Sport Lisboa acquired Grupo Sport Benfica by mutual agreement and changed its name to "Sport Lisboa e Benfica". Despite the 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.
