In 1990, the Asian Football Confederation introduced the Asian Cup Winners' Cup, a tournament for the cup winners of each AFC nation, while the 1995 season saw the introduction of the Asian Super Cup, with the winners of the Asian Club Championship and Asian Cup Winners' Cup playing against each other. 2002–present: AFC Champions League The 2002–03 season saw the Asian Club Championship, Asian Cup Winners' Cup and Asian Super Cup combine to become the AFC Champions League.
