Timnas Indonesia is set to open its campaign in the FIFA ASEAN Cup 2026 under head coach John Herdman, with preparations centering on a projected 3-4-2-1 formation and a renewed tactical identity, according to reports from regional sports outlets. The squad’s opening fixture brings a high-stakes clash against Singapore at the Gelora Bung Karno Main Stadium in Jakarta on Friday, September 25, 2026.
Tactical Setup and Squad Composition for the ASEAN Cup Opener
Head coach John Herdman has named a 23-player roster for the regional tournament, aiming to establish an aggressive and structured style of play from the opening whistle. According to previews published by iNews, the coaching staff’s training sessions point toward a 3-4-2-1 tactical framework designed to maximize central midfield control while maintaining defensive stability against counter-attacks.
The defensive structure faces a notable reshuffle following fitness concerns in the backline. With center-back Jay Idzes ruled out due to injury, according to reporting from iNews, Herdman is expected to deploy a three-man central defense featuring Elkan Baggott, Rizky Ridho, and Justin Hubner to protect the penalty area.

Detiksport highlighted the tactical stakes surrounding the fixture, noting that The Lions have adjusted their preparation to counter a transformed Indonesian roster. Singapore head coach has integrated key veterans back into the fold, including the return of forward Faris Ramli, alongside midfielder Kyoga Nakamura, who has committed to playing an all-out role for the national team as reported by Pontianak Post and MetroTVNews.com.
