On the international stage, Fetisov is one of the most decorated players ever. As a junior, Fetisov competed for the Soviet Union at the European Junior Championships, where he won Top Defenceman honors during the 1975–76 season, en route to two consecutive gold medals at the tournament. He then helped the Soviets to three consecutive gold medals at the World Junior Championships from 1976 to 1978, taking back-to-back Top Defenceman honors in 1977 and 1978.
