Celta de Vigo

Real Club Celta de Vigo (Galician pronunciation: [reˈal ˈkluβ ˈθelta ðe ˈβiɣo]), or simply Celta Vigo or sometimes just Celta, is a Spanish professional football club based in Vigo, Galicia, currently playing in the Liga. It was founded on 23 August 1923 following the merger of Real Vigo Sporting and Real Fortuna Foot-ball Club. Nicknamed Os Celestes (The Sky Blues), they play in sky blue shirts and white shorts. The club's home stadium is Balaídos, which seats 29,000 spectators. Celta's name is derived from the Celts who were once present in the region. Its main rival is fellow Galician club Deportivo La Coruña with whom it plays the Galician derby.

Despite playing many seasons in La Liga, Celta have never won the league title nor Copa del Rey, although it has reached the final 3 times in the latter. One of the team's best seasons was 1970–71, when they finished unbeaten at home and were known as the "giant-killers." Celta came sixth that season and qualified for the UEFA Cup for the first time. More recently, the club finished in their best-ever position of fourth in 2002–03, qualifying for the 2003–04 UEFA Champions League, where they were eliminated by Arsenal in the Round of 16.
