The Asian Cup has generally been dominated by a small number of top teams. Initially successful teams included South Korea (twice) and Iran (three times). Since 1984, Japan (four times) and Saudi Arabia (three times) have been the most successful teams, together winning seven of the last ten finals. The other teams which have achieved success are Qatar (2019 current champions), Australia (2015), Iraq (2007) and Kuwait (1980). Israel won in 1964 but was later expelled and has since joined UEFA.
