Villarreal Club de Fútbol, S.A.D. (Vila-real Club de Futbol, S.A.D.), usually abbreviated to Villarreal CF or just Villarreal, is a Spanish football club based in Vila-real, a city in the province of Castellón within the Valencian Community. Founded in 1923, it plays in La Liga, holding home games at El Madrigal, with a capacity for 24,890 spectators.
The club is nicknamed El Submarí Groguet or El Submarino Amarillo (Yellow Submarine) due to its yellow home kit, and due to being a low-profile team compared to Real Madrid, Barcelona, and Valencia, whom they have challenged for trophies over the last decade. Villarreal has often been touted as an example of small but successful club.
