Atletico Tucuman is a professional football club based in the city of San Miguel de Tucuman, Argentina. The club was founded on September 27, 1902, and it's one of the first social and sports clubs in the north of the country. It has a historical rivalry with San Martin de Tucuman.

In the first years of foundation, the institution was not known by "The Dean" nickname, but rather had nicknames with a more social connotation at that time. For this reason, the supporters of Atletico were first considered as "ojitos verdes" or "pitucos". This was due to the location of their stadium and the social level they had, which was much higher than that of the fans of their lifelong rivals from San Martin, who were known as "greengrocers" or "surgeons", due to their proximity to the market (Mercado de Abasto).

The "Dean" nickname was given many years later, due to since when it was baptized, Atletico had been the first soccer club founded in the Argentine North and one of the pioneers of the entire country. That is, the C.A.T. was the dean for the years that he had been spreading his football through the Argentine fields.

Atletico Tucuman was the first team in all of Argentina to wear a jersey with vertical white and light blue stripes. It's also worth noting, that the design of the shirt and the colors of the club weren't changed throughout all of history.

One of the club's most notable players is Luis Miguel Rodriguez, also known as "Pulga" Rodriguez, who played for the team for several years and helped to lead Atletico Tucuman to historic achievements, including promotion to the Primera Division and a Copa Argentina title in 2017.

Atletico Tucuman barra brava, known as La Inimitable, is dominated by two families who are actually blood relatives: the González and the Acevedo. Both families have many political connections and once managed to hang the La Inimitable flag from the balcony of the government house in Tucuman.

Argentinos Juniors is a sports club based in La Paternal, Buenos Aires. The club is most known for its football team, which plays in the Argentinean Primera División. One of the club's nicknames is "Bicho Colorado" (Red Bug), which came from a famous newspaper headline in the 1950s that read "Arrasan los bichos colorados" (Red bugs sweep all before them). The club is also nicknamed El Semillero, meaning the Nursery or The Seed Garden, because of its ability to keep producing world-class football players.

The absolute icon of the club is Diego Maradona, whose career started at Argentinos Juniors. In his honor, the club's stadium is named Estadio Diego Armando Maradona. It holds El Templo del Fútbol museum as well as the murals gallery on the stadium facade, mostly dedicated to Diego. Other famous players who started their careers at Argentinos Juniors are Juan Román Riquelme, Esteban Cambiasso, Juan Pablo Sorín, and Fernando Redondo.

The club is one of the eight Argentinean teams that have won the Copa Libertadores. The continental trophy was won in the club's first entry to the contest, in 1985. The club has had many rivalries, but their first-ever clásico was with Sportivo Italiano, who currently do not play professional football, which has led to their more recent rivalry against Platense with the most prominent clashes in the 80s.
