The match is scheduled for 8:00 pm local time, with Vietnam aiming to seal top spot in the group and carry momentum into the semifinals as they continue their title defense.
For Cambodia, the fixture carries little competitive significance after their elimination from semifinal contention.
Speaking at a pre-match press conference, Vietnam's head coach Kim Sang Sik emphasized that his team would approach the game with full focus and respect for their opponents.
"We respect Cambodia. However, our objective is to win the match and qualify for the semifinals as Group A winners," the South Korean coach said.
Vietnam enter the competition in impressive form, remaining unbeaten throughout the tournament.
They have scored 10 goals without conceding, including an emphatic 3-0 victory over Indonesia in their previous outing.
Indonesia had been considered one of the leading contenders for the title, making Vietnam's performance even more convincing.
Cambodia, by contrast, have struggled throughout the campaign.
They have recorded one win and two defeats while conceding seven goals.
While squad rotation may become a consideration later in the match, coach Kim is expected to prioritize securing victory before resting key players.
Vietnam also boast several attacking players in excellent form, including Xuan Son, Dinh Bac, Hai Long, Hoang Hen, and Tai Loc, giving the hosts significant firepower against the guests.
Statistical projections support Vietnam's status as overwhelming favorites.
