Vietnam trained in heavy rain at Acamanik Stadium in Bandung on September 27 ahead of its second 2026 FIFA ASEAN Cup match against Thailand. VnExpress observed coach Kim Sang-sik joining the warm-up after the 1-0 win over the Philippines.

The previous starters largely did recovery work, while substitutes and second-half entrants trained on the pitch. Hoang Duc returned to warm-up activities after injury, but the session did not confirm him as a starter against Thailand.
