In the earlier kick-off, Malaysia defeated Cambodia 3-1Â at Bishan Stadium.
The tournament, supposed to have been held late last year, was delayed a year due to the Covid-19 pandemic.
Junior Eldstal, whose purpose in the side was to provide a shield in front of the defence, was sloppy on the ball and constantly robbed in possession inside his own half as he looked severely off the pace.
Malaysia emerged champions in 2010 and finished runners-up in 1996, 2014 and 2018, placing them among four nations who have won the biennial tournament, which began in 1996.
Initially, countries such as Thailand, Cambodia, Vietnam, and Indonesia, were interested in becoming the host of the tournament, but due to the pandemic and its restrictions, Singapore was chosen as the host of the tournament.
Understandably, but perhaps surprisingly given the boldness of its nature, it led to Malaysia coach Tan Cheng Hoe replacing Eldstal after just 27 minutes.
