Unione Calcio Sampdoria, commonly known as Sampdoria [samp?d?rja], is an Italian association football club based in Genoa. The club was formed in 1946 from the merger of two existing sports clubs whose roots can be traced back to the 1890s, Sampierdarenese and Andrea Doria. Sampdoria currently compete in Serie A. Both the team name and jersey do reflect this, the first being a combination of the former names, the second incorporating the former teams' colours (blue-white and red-black) in a single design. The team's colours are blue with white, red and black hoops, hence the nickname blucerchiati ("blue-circled"). Sampdoria play at Stadio Luigi Ferraris, capacity 36,536, which it shares with Genoa's other club, Genoa Cricket and Football Club. The derby between the two teams is commonly known as the Derby della Lanterna. Sampdoria have won the scudetto only once in their history, in the 1991 season. The club has also won the Coppa Italia four times (1985, 1988, 1989, and 1994) and one Italian Super Cup. Their biggest European success came when they won the Cup Winners' Cup in 1990. They also reached the European Cup final in 1992, losing 1–0 to Spanish side FC Barcelona after extra time.
