Hosts Vietnam failed to make it to the finals of the Southeast Asian Futsal Championship after losing 0-2 to Malaysia in Ho Chi Minh City on Friday.
Vietnam, Indonesia and Malaysia were seen as title contenders in the regional indoor football contest that had five participants including Myanmar and the Philippines.
After round-robin matches between the five teams the two top teams will vie for the title in the final match on Sunday (April 11).
The Indonesians booked their final berth with nine points after coming back from a goal down to beat Vietnam 2-1 on Thursday.
Vietnam had the same six points as Malaysia but was in second place on goal difference, so all they needed was a draw with Malaysia to play the finals.
However, Thursday's defeat to Indonesia seemed to rob the team of courage and confidence.
They started the encounter with Malaysia in low spirits, in total contrast to their opening matches that they won 8-1 win and 4-0, beating the Philippines and Myanmar respectively.
Malaysia thus gained better control of the match and created five chances in the first half due to mistakes in the hosts' defense, but no goal was scored.
The Vietnamese players played better after the break and created several chances but Quoc Tuan, Quoc Bao and captain Bao Quan failed to convert them.
Then, in the final three minutes of the match, the hosts conceded two goals to be reduced to the role of spectators in the final match.
Indonesia, meanwhile, thrashed the Philippines 4-0 to remain unbeaten in the run up to the final.
