Club Atlético Unión (; mostly known as Unión de Santa Fe ) is a sports club from Santa Fe, the capital city of the Santa Fe Province, in Argentina. The club was founded on April 15, 1907 and plays in the Argentine Primera División. Although Unión is mostly known for its football team, that currently plays in Primera División, the club hosts other sports such as archery, basketball, field hockey, gymnastics, martial arts, roller skating, swimming and volleyball. History In 1966, the squad was promoted to the Segunda División Argentina for the first time. Unión's supporters are called "unionistas", "tatengues", while the squad is usually nicknamed "El Tate". The colours of the club consist of red and white vertical stripes. Managed by Juan Carlos Lorenzo in 1975, Unión made a great campaign in the 1975 championship with a group of notable players such as goalkeeper Hugo Gatti, midfielders Victorio Cocco and Rubén Suñé and forwards Ernesto Mastrángelo and Leopoldo Luque among others. In 1979 Unión played the final matches of the Nacional championship, but lost at the hands of River Plate, because the goal scored by River in the first match (with a final score of 1–1) ended up in an average over Union according to the away goals rule applied to that tournament. The most famous footballers who played for Unión are Leopoldo Luque, World Cup winner with Argentina in 1978, and Nery Pumpido, the goalkeeper of the national team that won the World Cup in Mexico 1986. Apart from football, basketball is the foremost sport practised at the institution, with Union's team currently in the third division. Carlos Delfino is its most famous basketball player, and Mario Elie, champion in NBA (1994, 1995 y 1999), also played briefly in the Argentine League, for Unión de Santa Fe. Rivalry Unión and Colón are the two largest football clubs in Santa Fe. The Clásico Santafesino is known as one of football's fiercest and most important rivalries in Argentina.
