The tournament, which features the 11 countries in the Asean region, was held on a home-and-away basis in 2018 but will be played in a centralised format due to the Covid-19 pandemic.

The competition has already been delayed by a year after being postponed because of coronavirus restrictions.

Defending champions Vietnam have been drawn to play Malaysia, Indonesia, Cambodia and Laos in Group B.

Hosts Singapore are in Group A and will meet Thailand, Myanmar, the Philippines and the winner of a playoff featuring Brunei and Timor Leste.

The opening game will be on Dec 5 with the final scheduled for Jan 1.
