When VAR Is Silent: Theerathon's Hand and the 2026 AFF Cup Haunting

On the evening of December 30, 2026, My Dinh Stadium was flooded with red flags. The first leg of the 2026 AFF Mitsubishi Electric Cup final between Vietnam and Thailand was in the 52nd minute. From a corner kick on the right side, the ball was lofted into the penalty area. In a breathless moment, veteran defender Theerathon Bunmathan raised his left arm high, blocking the path of the ball. The entire stadium seemed to explode in screams. Vietnamese players raised their hands for a penalty. Referee Ahmed Al-Kaf, the whistle-bearer from Oman, pointed toward the goal, signaling that the ball had gone out. No penalty. No VAR. No justice. For millions of Vietnamese football fans, that moment felt like a knife cutting into fairness. This final was not merely a match. It was a life-or-death battle against Southeast Asia's number one rival, a chance to assert regional dominance that Vietnamese football had awaited for years. And it was a stage where the faith of supporters could be properly rewarded. Let us contextualize. In the 2026 AFF Cup group stage, Vietnam finished top of Group B with a perfect 10 points, scoring 10 goals and conceding just 1. Thailand, the defending champions, also won all their matches in Group A. Both teams were in outstanding form. In the semifinals, Vietnam overcame Indonesia with an aggregate score of 2-0, while Thailand defeated Malaysia 3-0 on aggregate. A dream final. The first leg at My Dinh unfolded as expected. Vietnam started aggressively, pressing high and constantly putting pressure on Thailand's defense. In the 47th minute, Nguyen Tien Linh rose above the defense to head home the opening goal from Vu Van Thanh's cross. The stadium erupted. But the joy was short-lived, as just minutes later, the ball struck Theerathon's hand. Let us talk about the laws. Law 12 of the IFAB Laws of the Game governs handball offenses. According to IFAB guidelines updated in 2026, a player commits an offense if the hand touches the ball and the hand/arm is not in a natural position, or if it makes the body unnaturally bigger. The hand and arm below the shoulder are considered part of the offense zone; the shoulder is not. When the ball strikes the arm below the shoulder, especially if the arm is extended sideways or above shoulder height, the referee is entitled to award a penalty. In the 52nd-minute incident, Theerathon stood in the penalty area with his left arm raised to shoulder height, with no significant direct challenge around him. The ball arrived from the cross and hit his arm directly. Clearly, his arm was not in a natural position. Under the IFAB guidelines, this was a textbook penalty. So why did Al-Kaf not blow his whistle? Reviewing the slow-motion replay, we can see that the referee was in an unfavorable position. His line of sight was partially blocked by a Vietnamese player running across. Moreover, in a final, referees tend to be cautious: they do not want to make a match-defining decision based on an unclear view. But the painful truth is that this very caution killed fairness. If VAR had been available, Al-Kaf could have reviewed the screen, checked the angle, and made the right call. Unfortunately, the 2026 AFF Cup did not use VAR. Throughout the 90-plus minutes at My Dinh, there was no video assistant referee support. And incorrect decisions, whether accidental or from lack of information, stood. VAR is not wrong. What is wrong is our belief that it can replace a night of refereeing errors. But at My Dinh that night, VAR was not even there to replace anyone. On the night of facing VAR's absence, I learned that technology is not at fault. Those who operate it are. The problem lies with people, with Southeast Asian football administrators who decided that the cost of installing VAR was unnecessary for a regional tournament. But have they ever asked: what is the price of a wrong decision in a final? Imagine this. If referee Al-Kaf had awarded a penalty in the 52nd minute, and if Nguyen Quang Hai had converted, the score would have been 2-0. Thailand would have been forced to push forward. They would have played more recklessly, leaving more space for Vietnam's counterattacks. History might have been written differently. But no, the ball was not placed on the spot. Anger and frustration enveloped the team, and Vietnam began to lose composure. They still controlled the ball, but their passing became less precise. Thailand, with the composure of a seasoned team, seized the moment. In the 77th minute, they equalized to make it 1-1. Vietnam fought back and regained the lead at 2-1 through a beautiful long-range strike from Vu Van Thanh in the closing minutes. But in stoppage time, they lost the win when Sarach Yooyen scored the 2-2 equalizer from a corner kick. The match ended in a draw, a bitter result for Vietnamese fans. Would things have changed with VAR? The answer is almost certainly yes. The AFF Cup is a major brand in Southeast Asian football. The tournament's main sponsor is Mitsubishi Electric, a leading Japanese corporation. Additionally, revenue from broadcasting rights is distributed to member associations and represents a significant income source. Yet, in an era where referee technology has become a global standard, the AFF Cup remains outside the game. The cost of a mobile VAR system for an entire tournament is estimated at around 1 million USD, including equipment rental, operational staff, and training. One million USD – a small sum compared to the revenue of a tournament whose major sponsor spends tens of millions. Even in Vietnam, the V-League experimented with VAR in some matches in the 2026 season with positive results. So why is the AFF Cup still so outdated? Look at the world. At the 2026 World Cup in Qatar, VAR intervened in numerous situations, including disallowed goals for marginal offsides. At the 2026 AFC Asian Cup in Qatar, all matches had VAR. In the UEFA Champions League, VAR is mandatory. Even national leagues of less developed countries like India have adopted VAR in the final stages. Southeast Asian football, home to over 600 million people and some of the most passionate football fans in Asia, remains one of the few regions lagging behind. Based on my experience following matches in the Bundesliga, where VAR has been in use since 2026, I can confidently say that this technology not only reduces errors but also creates a sense of fairness for teams. Of course, VAR still sparks controversy, but at least it provides an objective standard. Without VAR, football becomes a game of human-created chance. The 2026 AFF Cup final was a wake-up call. If VAR remains absent, similar scandals will continue. More importantly, the national teams themselves will suffer the consequences. Southeast Asian football deserves fair treatment. Let the whistle no longer be a source of fear, but a guarantee of fairness powered by technology.
