What are the weaknesses of the Indonesian national team?

Indonesia, facing Vietnam at Pakansari this evening, features a team of quality naturalized players, a contemporary style of play, excellent physical conditioning, and many individuals capable of changing the game. Yet, they do have some vulnerabilities...

Behind that impressive facade, John Herdman's team still has an "Achilles heel" that opponents, especially Vietnam, can target.

The comprehensive strength of the top contender.

Under John Herdman, Indonesia has taken on the appearance of a team that knows how to control the game, organize methodical attacks, and apply constant pressure. The foundation for this change is the quality of naturalized players, even though they have not yet fully utilized this strength. These players bring a modern football mindset and a physical edge that surpasses the Southeast Asian standard.

Physique is Indonesia's most prominent advantage. Their tall players give them near-total dominance in physical duels, especially in midfield. Ivar Jenner is a prime example. This midfielder is not flashy but highly effective at reading the game, intercepting, and regaining possession, laying the foundation for Indonesia to control the tempo.

Up front, Mitchell Lee Baker (4 goals in 2 matches) is becoming the tournament's phenomenon. Not only does he possess diverse finishing abilities, but this 1.96m striker is also the ideal target for every cross and set piece. And when it comes to dead balls, one cannot ignore the "brain" Thom Haye. This midfielder not only regulates the game but also has highly accurate free kicks. His three assists for Baker against Cambodia and the free-kick goal against Timor Leste show that whenever Indonesia gets a set piece near the box, the opponent faces a major threat.

John Herdman's tactical imprint is clearly shown in how Indonesia builds from the back. The second goal against Cambodia is evidence: the ball was circulated through 11 passes in over half a minute before Eliano Reijnders crossed for Baker to finish. This is no longer football driven by inspiration, but the product of a well-organized system.

Squad depth is another differentiator for Indonesia compared to the rest of the region. Even when rotating the lineup, the professional quality does not drop significantly. This allows Herdman to have more options to adjust against each opponent and maintain high intensity throughout the tournament.

Additionally, there is the home advantage. Tens of thousands of fans at Pakansari always create a passionate atmosphere, boosting the energy of Indonesian players. In big matches, that support can become a "12th man," putting significant pressure on the visiting team.

The Achilles heel remains.

In the opening match against Cambodia, Nadeo Argawinata started but made a mistake leading to the only goal conceded. Immediately, coach John Herdman gave Cahya Supriadi a chance in the match against Timor Leste. Cahya has quick reflexes but is only about 1.80m tall, quite modest. The goalkeeper, born in 2003, also lacks international experience, leaving his handling under high-pressure situations a question mark.

This is a point that opponents with good attacking organization can fully exploit. If they apply enough pressure or consistently send the ball into the box, Indonesia risks revealing errors from their goalkeeper.

But Indonesia's biggest "Achilles heel" is perhaps psychological. The most expensive squad in the tournament, a large number of naturalized players, a coach who succeeded with Canada, and two convincing recent wins have raised fans' expectations to unprecedented levels. John Herdman himself has not shied away from setting the sole objective as the championship.

However, history is not easily overcome.

Indonesia has reached the ASEAN Cup final six times but lost every time. It is a paradox that has lasted three decades: always possessing great potential but never winning the title. Hence, they are often likened to the "uncrowned king" of Southeast Asian football.

After the shock of missing out on the 2026 World Cup, the ASEAN Cup trophy has become a mandatory goal to prove that the naturalization revolution is truly successful. If they cannot win, all the praise today could quickly turn into harsh criticism. That pressure inadvertently creates a psychological burden. When everyone expects victory as a given, every small mistake can easily make players lose composure. Teams under pressure to win often face more difficulties when trailing or in stalemates against equally matched opponents.

And objectively speaking, the two wins over Cambodia and Timor Leste are not yet a big enough test. Both opponents are rated significantly lower than Indonesia. Therefore, it is too early to say that Herdman's squad is completely polished. The clash with Vietnam is an opportunity for Indonesia to prove they have the mettle to overcome strong opponents under the greatest pressure.
