Vietnamese defender Xuan Manh kisses coach Kim Sang Sik lucky black shirt

Public sentiment swung from calls for apologies to immediate adulation as Vietnam erased the memory of a frustrating home draw with a commanding 3-0 away victory against Indonesia in the ASEAN Cup 2026. Just days after facing sharp criticism over conservative tactics and late substitutions during a stalemate with Singapore at Mỹ Đình Stadium, head coach Kim Sang Sik silenced his doubters through a radical starting line-up overhaul that completely caught his opponents off guard.

The tactical gamble materialized less than an hour before kickoff on August 3 at Pakansari Stadium in Indonesia, according to reports from Znews. Abandoning the exact starting XI he had deployed in earlier fixtures against Timor-Leste and Singapore, Kim benched several prominent names — including Nguyễn Quang Hải, Đoàn Văn Hậu, and Đỗ Hoàng Hên — and limited his use of naturalized players to just one starter. The bold rotation injected fresh energy into the squad, yielding immediate dividends as unheralded starters seized control of the pitch.

Nguyễn Hai Long emerged as the standout catalyst, scoring one goal and earning the tournament's official Cầu thủ giàu năng lượng nhất (Most Energetic Player) award from the ASEAN Cup 2026 organizers for his relentless pressing and movement. Meanwhile, veteran midfielder Lê Phạm Thành Long orchestrated the tempo, supplying a precise cross-field assist that dismantled the Indonesian defense to set up Hai Long's strike. Defensive stability was anchored by Bùi Hoàng Việt Anh, who stepped in at right-center-back to neutralize tournament top scorer Mitchell Baker while maintaining goalkeeper Lê Giang Patrik's third consecutive clean sheet, as documented by Sofascore statistics cited by Znews.

While Vietnamese outlets focused heavily on these precise tactical adjustments and physical execution, South Korean media outlets found a lighter narrative to spotlight. Publications including Dantri and Soha detailed widespread coverage from outlets like *Nate*, *Etoday*, and *Top Star News* regarding Kim's superstition surrounding his lucky black polo shirt. Having worn white during the draw with Singapore, Kim returned to black against Indonesia, prompting defender Phạm Xuân Mạnh to celebrate the victory by kissing the coach's shirt. Kim joked after the match that he would throw away all his white clothes and instruct his wife never to buy any more.

Beyond the superstitious banter, the strategic reversal left Group A firmly under Vietnamese control. Holding a commanding lead at the top of the standings, the team secured their return flight to Hanoi immediately after the match, as reported by Tiin and *Baovanhoa*.

The squad's immediate priority upon returning home is physical recovery ahead of their final Group A fixture against Cambodia at Mỹ Đình Stadium on August 7.

Tactical Evolution and Group Control

The transformation on the pitch stood in sharp contrast to the tactical stagnation observed days earlier against Singapore, where late substitutions drew public scrutiny. According to analysis from Znews, the manager delayed his changes until stoppage time during the stalemate at Mỹ Đình Stadium, bringing on substitutes only in the ninety-second minute. Against Indonesia, however, proactive intervention defined the contest. Introducing attacking personnel while holding a two-goal advantage allowed the team to secure a third goal just minutes later, illustrating a decisive shift in match management.

The logistical turnaround mirrored the tactical velocity. Tiin and *Baovanhoa* reported that the squad immediately caught a return flight to Hanoi following the final whistle at Pakansari Stadium. Physical recovery remains the immediate priority upon arrival, ensuring the players regain their stamina before the next step of the campaign, their final Group A fixture against Cambodia at Mỹ Đình Stadium on August 7, 2026.
