Zona mista proved highly successful at national and international level: with it, Torino won the 1975–76 Serie A, its first after the Superga air disaster; Juventus played some of its finest football ever, setting the most enduring record in the history of Italian football by winning six league titles and two cups in ten years. Juventus then extended this success to the international arena, starting in 1977 when the club won the UEFA Cup without foreign footballers, an unprecedented achievement for any country's team. Subsequently, it lifted the Cup Winners' Cup, the European Champions Cup, the UEFA Super Cup and the Intercontinental Cup, making it the first, and so far only, club to have won all possible official international competitions. These achievements lifted the Serie A for the first time to the top of the confederation ranking at the end of the 1985–86 season, a position maintained for the following three seasons.
