Villarreal Club de Fútbol, founded in 1923 in eastern Spain, is a professional football club known as "El Submarino Amarillo" (The Yellow Submarine) due to its distinctive kit and humble origins compared to Spanish giants. After decades in lower divisions, the club achieved promotion to La Liga, Spain's top flight, in 1998 and has since established itself, even rebounding swiftly from a 2012 relegation. Villarreal made its UEFA Champions League debut in 2005, impressively reaching the semi-finals in both 2006 and 2022. Its greatest triumph arrived in 2021 when they secured their first major trophy by winning the UEFA Europa League, defeating Manchester United in a memorable final. Playing at the Estadio de la Cerámica, Villarreal is widely celebrated as an inspiring example of a smaller club achieving remarkable success on both national and international stages.
