Under the management of Giovanni Trapattoni, the club won 13 trophies in the ten years before 1986, including six league titles and five international titles, and became the first to win all three seasonal competitions organised by the Union of European Football Associations: the 1976–77 UEFA Cup (first Southern European side to do so), the 1983–84 Cup Winners' Cup and the 1984–85 European Champions' Cup. With successive triumphs in the 1984 European Super Cup and 1985 Intercontinental Cup, it became the first and thus far only in the world to complete a clean sweep of all confederation trophies; an achievement that they revalidated with the title won in the 1999 UEFA Intertoto Cup after another successful era led by Marcello Lippi, becoming in addition the only professional Italian club to have won every ongoing honour available to the first team and organised by a national or international football association. In December 2000, Juventus was ranked seventh in the FIFA's historic ranking of the best clubs in the world and nine years later was ranked second best club in Europe during the 20th century based on a statistical study series by the International Federation of Football History &amp; Statistics (IFFHS), the highest for an Italian club in both.
