Herdman calls Indonesia vs Malaysia match a Newcastle-Sunderland derby: Indonesia's emotional test

Indonesia head coach John Herdman has compared Friday's ASEAN Cup 2026 Group A match against Malaysia to the Newcastle-Sunderland derby, calling it a test of emotion and discipline. Both teams won their opening matches: Indonesia beat Singapore 2-0, Malaysia beat Bangladesh 3-0. The match takes place on September 28 at Gelora Bung Karno Stadium. Herdman, a former Canada coach, stressed that his players must give maximum effort and not underestimate their rivals. The derby comparison is not casual: it reflects concern about complacency and emotional control. In derby matches, the stronger team is often the first to lose composure. Malaysia could defend deep and rely on counterattacks, while Indonesia may struggle with the pressure of a packed home crowd. The tactical data is thin. Malaysia's 3-0 win over Bangladesh says little about their quality; Indonesia's 2-0 win over Singapore may be more meaningful. Yet in a Southeast Asian derby, logic and form often matter less than discipline. If Indonesia stay calm in the first 20 minutes, they should win. If they let the crowd dictate their rhythm, Malaysia could punish them. The statement is also a risk: it raises expectations and pressure. Herdman is preparing for the worst-case scenario, where emotion breaks the team's structure. The answer will come on the pitch. The question is not which side is better, but which side can play a derby without losing their head.
