FC Barcelona in European football The European Cup was inaugurated in 1955, with Barcelona's arch-rivals Real Madrid winning the first five editions.[15] In 1959, Barcelona entered this competition for the first time, after winning the 1958–59 La Liga season. Until the 1990s, the club had little success, apart from their runner-up places in 1961 and 1986. In 1992, Johan Cruyff's Dream Team[16] won their first European Cup with a 1–0 win against Sampdoria. Since then, Barcelona has won the competition four additional times, in 2006, 2009, 2011 and 2015. Barcelona has established itself as one of the strongest sides in European competitions, when measured in UEFA coefficients.[3][17]
