With the Thais victorious in their opening two matches, a third consecutive victory would keep them in a comfortable position at the summit with a perfect record of nine points, which is almost always enough to guarantee progress to the semifinals.
In that event, both Thailand and Singapore will be level on nine points with Philippines and Myanmar stuck on three apiece, making it mathematically impossible for the top two to be overtaken.
A win for Philippines, however, would move them level with the Thais and leave them with their fate in their own hands, a prospect that coach Stewart Hall believes is absolutely vital.
"It was a big confidence boost getting the win in the last match (a 7-0 win over Timor-Leste) but we need to keep winning, and likely we need to keep winning well," said the Englishman.
"Of course, that doesn't mean we need to try and beat (Thailand) 4-0 or 5-0, but we're under no false hopes as to what is required. And that starts with the win."
In a slight boost to the Azkals' prospects for Tuesday, record five-time champions Thailand have been hit by the withdrawals of goalkeeper Kawin Thamsatchanan and Jonathan Khemdee to family and fitness-related issues respectively, although they have brought in a reinforcement in the form of Philip Roller.
Despite the emphatic nature of Philippines' win over the Timorese last time out, Thailand coach Alexandre Polking is not particularly fazed by that result.
"I've said it before that Philippines played a Timor-Leste side with many changes and so they didn't especially impress me, considering Timor-Leste didn't bring on their main players until the second half," reiterated Polking, whose own side were impressive as they beat Myanmar 4-0 on Saturday.
"It's a very important game and it can be a decider for reaching the semifinals, so we've focused a lot on recovery and analysis."
