Myanmar booked their spot in Monday's final by beating an in-form Vietnam 2-1 in the semi-finals, while Thailand crushed Indonesia 5-0.
Thailand have scored 21 goals and conceded just one during their Games campaign, and have been a dominant force throughout. Despite this, Choketawee knows that Myanmar pose a big threat to his side.
"Yes, 21 goals very good for the result but every game, we just need three points," Choketawee told reporters. "Myanmar are very strong. They run a lot and 90 minutes, they will never stop."
Choketawee believes that Myanmar will come into the final on a high as they weren't expected to beat Vietnam, who had only been beaten by Thailand up to that stage.
"They now also have confidence from their results so we will talk to our players and make sure they understand this final is not easy for us," he said. "We must work hard, do our homework and focus."
