history to achieve an international title with a squad composed by national footballers. In 1993, the club won its third competition's trophy, an unprecedented feat in the continent until then, a confederation record for the next 22 years and the most for an Italian team. Juventus was also the first club in the country to achieve the title in the European Super Cup, having won the competition in 1984, and the first European side to win the Intercontinental Cup in 1985, since it was restructured by Union of European Football Associations (UEFA) and Confederación Sudamericana de Fútbol (CONMEBOL)'s organizing committee five years beforehand. The club has earned the distinction of being allowed to wear three golden stars () on its shirts representing its league victories: the tenth of which was achieved during the 1957–58 season, the twentieth in the 1981–82 season and the thirtieth officially in the 2013–14 season. Juventus were the first Italian team to have achieved the national double four times (winning the Italian top tier division and the national cup competition in the same season), in the 1959–60, 1994–95, 2014–15 and 2015–16 seasons. In the 2015–16 season, Juventus won the Coppa Italia for the eleventh time and their second-straight title, becoming the first team in Italy's history to complete Serie A and Coppa Italia doubles in back-to-back seasons; Juventus would go on to win another two consecutive doubles in 2016–17 and 2017–18. In 1985, Juventus became the first club in the history of European football to have won all three major UEFA competitions, the European Champion Clubs' Cup, the (now-defunct) UEFA Cup Winners' Cup and the UEFA Cup, being also the only one to reach it with the same coach. After their triumph in the Intercontinental Cup in the same year, Juventus also became the first football team ever—remaining the only one at 2022—to have won all possible official confederation tournaments. Only in the 1910s the club has not won any official competition, a unique case in the country. In terms of overall official trophies won, Juventus' most successful decade was the 2010s. In that period the club won eighteen competitions, ahead of the 1980s and 1990s (both with eleven titles).
