Clube Desportivo Nacional, commonly known as Nacional and sometimes Nacional da Madeira (Portuguese pronunciation: [nɐsiuˈnaɫ dɐ mɐˈdɐjɾɐ]), is a Portuguese football club based in Funchal, in the island of Madeira. Founded in 1910, it currently plays in the Portuguese first division.

Nacional reached the first division for the first time ever in the mid-90s, returning again in 2002–03. The following season was arguably the best ever season, as the side finished fourth in the league, just squeaking past Sporting Clube de Braga. In that season, three of its key players were Paulo Assunção, a defensive midfielder, and goal-machine Adriano, who netted 19 times. Both would later go to F.C. Porto, while the third key player, winger Miguelito, joined Sport Lisboa e Benfica in 2006.

Nacional also had a quarter-final run in the domestic cup, and would lose in the first round of the subsequent 2004–05 UEFA Cup, being defeated twice by Sevilla FC. In 2006–07's edition, more of the same occurred with two early losses to FC Rapid Bucureşti.

Club Deportivo Guadalajara (Spanish pronunciation: [ɡwaðalaˈxaɾa]), (often simply known as Guadalajara) is a Mexican professional football club based in Guadalajara, Jalisco. Guadalajara plays in the Primera División de México (Mexican First Division) and is the most successful club in Mexican football, having won 11 First Division titles, 7 Campeón de Campeones, 1 InterLiga, 1 Copa Challenger, 4 Copa Oros de Occidente, and 2 Copa México. Guadalajara is one of the ten founding members of the Mexican First Division and along with longstanding rivals Club América it has never been relegated to the second-tier division. Most recently, Guadalajara is the runner-up of the 2010 Copa Libertadores.

C.D. Guadalajara is the only football club in Mexico to exclusively field players of Mexican heritage. The team has constantly emphasized home-grown (cantera) players and has been the launching pad of many internationally successful players, including Javier "Chicharito" Hernández, Carlos Vela, Omar Bravo and Carlos Salcido, among others. The team's three colors (red, white, and blue) symbolize "Fraternity, Union, and Sports". The team mascot, as well as their nickname, is the goat or chiva. According to FIFA Chivas are Mexico's most successful and popular team, and hold the Mexican league record for the longest winning streak at the beginning of a season, with 8 consecutive wins.
