Sarach Yooyen credited defensive discipline for Thailand's 2–0 FIFA ASEAN Cup win over Vietnam on September 29. In new comments cited by VnExpress on October 1, the midfielder expressed satisfaction with his goal and the team's clean sheet.

He opened the scoring from distance before Thailand prioritised defence and counter-attacks. Sarach highlighted concentration and tactical execution. These are the player's reflections on a completed match, adding to the result rather than independently establishing every cause of the outcome.
