Associazione Sportiva Roma, commonly referred to as simply Roma, is a professional Italian football club based in Rome. Founded by a merger in 1927, Roma have participated in the top-tier of Italian football for all of their existence except for 1951–52. Roma have won Serie A three times, in 1941–42, 1982–83 and 2000–01, as well as winning nine Coppa Italia titles and two Supercoppa Italiana titles. In European competitions, Roma won the Inter-Cities Fairs Cup in 1960–61 and were runners-up in the 1983–84 European Cup and the 1990–91 UEFA Cup. Fifteen players have won the FIFA World Cup while playing at Roma: Ferraris, Guaita and Masetti; Donati, Monzeglio and Serantoni; Bruno Conti; Rudi Voller and Berthold; Aldair; Candela; Cafu; Daniele De Rossi, Simone Perrotta and Francesco Totti. Since 1953, Roma have played their home matches at the Stadio Olimpico, a venue they share with city rivals Lazio. With a capacity of over 72,000, it is the second-largest of its kind in Italy, with only the San Siro able to seat more. The club plan to move to a new stadium, though this is yet to start construction.
