According to a Vietnam News Agency correspondent in Bogor, the most obvious weakness of Indonesia lies in the goalkeeper position. After Nadeo Argawinata's mistake in the opening match against Cambodia, coach John Herdman was forced to give Cahya Supriadi a chance in the game against Timor Leste. Although he possesses good reflexes, the goalkeeper born in 2003 still lacks international experience and also has no physical advantage, standing at only about 1.80 meters tall. This is seen as a link that opponents can pressure with aerial balls or consecutive shots inside the penalty area.
Additionally, Indonesia has shown an over-reliance on certain individuals. Thom Haye remains the "brain" in the playing style of the "Land of a Thousand Islands" team, while Mitchell Lee Baker is the most dangerous spearhead in attack. The two victories over Cambodia and Timor Leste both bore the strong imprint of this duo. If Haye's ability to organize play is limited or Baker is cut off from the midfield, Indonesia's attacking power could diminish significantly.
However, according to experts, Indonesia's biggest "Achilles heel" lies in the psychological factor. Six final appearances, all ending in defeat, have prevented this team from shedding the image of the "uncrowned giant" of Southeast Asian football. After missing out on the 2026 World Cup, winning the ASEAN Cup has become a mandatory goal to prove the success of the squad overhaul under coach John Herdman.
The pressure to win is itself becoming a double-edged sword for the host team. When expectations of victory are raised too high, every small mistake can create immense psychological pressure. In matches where the opponent plays tightly or unexpectedly takes the lead, Indonesia could easily become impatient and lose their composure.
In reality, the two wins over Cambodia and Timor Leste were not a true test of Indonesia's mettle. Against Timor Leste, Herdman's team had to wait until the 74th minute to break the deadlock, even though the opponent had been playing with a man down since the start of the first half. This shows that Indonesia still struggles against well-organized defensive systems.
That said, this does not mean Indonesia is an easy opponent to defeat. The "Land of a Thousand Islands" team still possesses many formidable advantages, from physical foundation, aerial ability, squad depth, to the support of tens of thousands of fans at Pakansari Stadium. For the Vietnam national team, correctly identifying the opponent's "Achilles heels" will be the key to gaining an advantage in a match that is considered decisive for the standings in Group A of the 2026 ASEAN Cup.
