Thailand assistant coach Choketawee Promrut has warned his side that they cannot afford to take the Philippines lightly in their Suzuki Cup semi-final second leg on Wednesday.
Kiatisuk Senamuang's side went unbeaten in the group stages of the competition, finishing top of Group B, setting up a final four clash against the Philippines.
The first leg of the tie was played on Saturday, with the two teams playing out a goalless draw.
Heading into Wednesday's deciding leg, Promrut says that there is no room for complacency.
"Our target is to win the title," he said.
"But we cannot underestimate any opponents and the Philippines proved in the first leg that they were tough to beat."
Wednesday's game will take place at the Rajamangala National Stadium in Bangkok, with kick-off at 19:00 local time.
