The Asean Football Federation (AFF) will implement changes to the format of its flagship tournament, the Suzuki Cup, in 2018
The current eight-team tournament proper will be expanded to include 10 of 11 Asean nations, with the 10th and 11th-ranked team playing off for a spot in the main draw.
There will be two groups of five teams each, with each side playing two group games in their home country, and two away.
A draw will determine the exact fixtures.
This is a step away from the current system, where four of the lowest-ranked teams in the region battle to earn one spot in the tournament proper.
The format of a two-leg, home-and-away semi-finals and final will remain.
