Proposed participating national football associations
8 country will take part in the competition. There will be no promotion nor relegation and a play-off system would determine the winner. 16 teams are expected to eventually compete in the league. Competition will be held on a club basis with each team allowed to register two players from an Asean country and six players from non Asean countries.
Note :- If Australia refuse to compete (as they have a significantly higher ranking in FIFA), then Laos, Cambodia, Brunei and Timor-Leste will be considered to compete based on their last ranking in FIFA before the tournament kicks-off. However only two teams will be selected with only one club slot for each team.
The format of the ASEAN Super League is the same as the format for the domestic league. Each football association in Southeast Asia will send two clubs. The participating teams will be playing in a round-robin format.
