Founded in Lisbon on 1 July 1906, they are one of the "Três Grandes" (The Big Three) football clubs in Portugal. With 120,000 club members, their teams, athletes and supporters are often nicknamed Leões (English: Lions) by their fans.
Sporting were a founding member of the Primeira Liga and, together with Benfica and FC Porto, have never been relegated from the First Division of Portuguese football since the league's establishment in 1934. Sporting are the third most successful Portuguese football club, with forty-four titles in Portuguese domestic competitions and one international title, the 1963–64 European Cup Winners' Cup. Domestically, they have won eighteen Primeira Liga titles, fifteen Portuguese Cups, four Championship of Portugal titles (a record tied with Porto) and seven Portuguese SuperCup titles.
Sporting CP entered the competition defeating Atalanta in the qualifying round, then past APOEL F.C. (in what was the biggest win in a single UEFA competitions game to date: 16–1), Manchester United, Olympique Lyonnais and in the end defeated MTK Budapest in a two round final to win their first European title.
Within Portugal, Sporting Clube de Portugal is often referred to simply as "Sporting". Outside Portugal, it is often known as "Sporting Lisbon". The club has attempted to shed this name, particularly through ex-president Sousa Cintra and his staff, in an effort to become known abroad by its correct name. Despite this, some non-Portuguese media still uses Sporting Lisbon due to precedent and to avoid confusion with other clubs such as Sporting Clube de Braga, Sporting Clube da Covilhã, Sporting Clube Farense, Sporting Clube Olhanense and Sporting de Gijón, instead of using a more accurate name like Sporting Portugal. UEFA has historically used the designation Sporting CP in English-language scorelines and match reports on its own site, but as of January 2010 uses the club's full Portuguese name.
The very first jerseys used were white. Starting in 1908 the jerseys has two colors - green and white - divided in two vertical sections separated at the center of the chest and back. The emblem on this shirts was placed in the left side of the shirt. Today this kit is known as "Stromp" and is currently used often as a third or fourth kit often seen used by sporting players in special occasions like finals or in the Portuguese Cup. The original white shorts that completed the original kit started to be black from 1915 onwards. The striped equipment (used as the first kit nowadays) started to be used by Sporting's rugby team and was only adopted by the football team in 1928 during a tour trough Brazil. Up to 1997/98 fully white or green shirts were used as a second kit. From 1998/99 onwards new alternative kits of several colors are presented every year.
Since its formation, on 1 July 1906, Sporting has had six badges, all of which have included the colour green and the lion. Sporting's badge includes a white lion (golden after 2001) standing up by its left paw over the color green. This was officially adopted in 1906 along with the green and white colors that are used since the creation of the club. In 1907, D. Fernando de Castelo Branco (Pombeiro) authorized that the lion that belonged to his family arms was used in the Sporting's badge. It should have been silver with a black background over the color green that would symbolize the "steady and pure hopes and intentions of the founders" . The green color was also suggested by the Viscount of Alvalade. From 1920 on the emblem started containing the letters SCP at the top, an image that was maintained during decades. Finally, in 2001, Sporting created a new and modernized graphical image. The new badge is coherent with the club's pass but adds the three white stripes based on the club's jerseys. It also includes the words "Sporting Portugal" written in full. The lion is presented in a more stylized fashion with a reinforced impact coming from the golden color. During the year 2005 sporting used a official badge to celebrate the century of the club where the past and the present were mixed. Modern symbols like the new badge or the golden lion were inserted over a circle with a divided background where the green, the phrase "Sporting 100" and the dates 1906-2006 are clearly seen.
Sporting's stadium, Estádio José Alvalade, was built for the UEFA Euro 2004 championship. The stadium was designed by Tomás Taveira and was classified by UEFA as a five-star stadium, enabling it to host finals of major UEFA events. This stadium has a capacity of 50,095 spectators.
