VAR in V-League: When Technology's Light Exposes the Dark Corners

VAR in V-League: When Technology's Light Exposes the Dark Corners In the match between Cong An Ha Noi (CAHN) and TP.HCM FC in Round 12 of the 2026-25 V-League, in the 67th minute, the ball struck a defender's arm inside the penalty area. Referee Ngo Duy Lan initially let play continue, but after more than two minutes of waiting, the VAR crew called him over to review the monitor. Nine minutes later, Nguyen Quang Hai converted the penalty, sealing a 2-1 win for CAHN. Home fans at Hang Day Stadium erupted, but on football forums an immediate question emerged: was the defender's arm in a natural position? And if VAR needed two minutes to decide, was the football we were watching still keeping its natural rhythm? Watching the referee huddle around the screen, I remembered something I wrote after spending three months relearning the entire IFAB Laws of the Game, when I realized I had once used an outdated rule to judge an offside situation at the 2026 World Cup: “It took me three months to understand that the arm is not part of the offside law.” But that night, we were dealing with a completely different law: Law 12, the handball offence. And as always, fans remember the goal, but I remember the rule. VAR officially began operating in the V-League in the 2026 season, with VPF investing in camera systems, a central VAR room at VFF headquarters, and dozens of FIFA-standard training courses. The declared goal was clear: reduce mistakes and increase transparency. But after two seasons, VAR has not only delivered justice. It has exposed another reality: the lack of consistency in applying a law that was already very vague. The handball rule is in Law 12 of IFAB. Under the latest text effective from July 2026, a player is considered to have committed an offence if they deliberately touch the ball with their hand, or if their hand makes their body “unnaturally bigger” and the ball touches that body part. The phrase “unnaturally bigger” is what gives referees, VAR crews and even sports lawyers headaches. What about an arm extended to keep balance while turning? What about an elbow tucked close to the body, with the ball bouncing up from the turf and hitting it? The law does not provide a mathematical formula — that is why two different people can watch the same incident and reach opposite conclusions. In the Hang Day incident, slow-motion replays from behind the goal showed the visiting defender jumping to contest a high ball with a CAHN forward, left arm extended sideways. The ball struck his bicep while he was in the air. Technically, the extended arm enlarged his body area, matching the “unnaturally bigger” description in Law 12. But context matters just as much: it was a defensive jump to head the ball clear, the ball came from close range, and the arm was not moving toward the ball in a deliberate motion. VAR took two minutes to decide. Two minutes is an eternity in a football match, and it raises a key question: if it takes that long, was the final decision truly “clear and obvious” as the VAR protocol requires? This is the core problem. The VAR protocol, designed by IFAB, is built on the principle of minimal intervention: the referee should only be asked to review the monitor when the VAR team identifies a “clear and obvious” error. If everything is ambiguous, the on-field decision must stand. Yet in V-League practice, we see too many VAR interventions caused not by obvious errors, but by differences in subjective judgement between VAR crews. The result is that referees are stripped of their authority, while the VAR team faces no media pressure at all. A match can be stopped, but the responsibility of the match official cannot — and that responsibility is gradually fading between two layers of decision-makers. Looking back at the 2026-24 season, there were at least four similar handball situations with completely contradictory VAR outcomes. In the Hanoi FC match against Viettel last October, defender Que Ngoc Hai stood close with his arms crossed over his chest; the ball hit his elbow but no penalty was awarded. Three weeks later, in a Thanh Hoa match, another defender had his arms in a similar position and the referee pointed to the spot. No official explanation was ever given. Fans could only shake their heads: is the law applied according to the individual or according to the match? The answer lies in a structural weakness. The V-League still lacks a unified guidance document for handball situations, something many top European leagues have built over the years. In the Premier League, referees receive guidance sheets with illustrations for every arm position, from arms close to the body to arms stretched wide, from moving arms to static arms. Each position has concrete examples for comparison. In the V-League, referees rely mainly on personal experience and a short pre-season workshop. When the law is unclear, those applying it cannot be consistent. That is what I call the gap between perception and rule: fans feel unfairly treated, while sports lawyers see a regulatory text being applied arbitrarily. But there is another, counter-intuitive angle rarely mentioned. VAR is quietly shifting power within Vietnamese football. Previously, the referee was the sole authority. Now, a VAR team sitting in a control room kilometres away holds almost absolute power. They can intervene at any time through messages in the earpiece, and referees rarely dare to overrule them. In the Hang Day match, after a two-minute wait, referee Ngo Duy Lan walked to the monitor, studied the replay for almost thirty seconds, and decisively awarded the penalty. That moment made me wonder: was he truly making his own judgement, or merely confirming a scenario the VAR team had prepared for him? If the referee becomes a mere formality, his leadership role on the pitch collapses. And once the pitch loses its leader, players easily descend into chaos. I remember watching the 2026 AFF Cup final between Vietnam and Thailand. In extra time, the ball struck a Thai player's hand in the box, but the referee immediately shook his head. He was close, just five metres away, and he dared to decide on the spot. That was a rare moment of courage. VAR can assist, but on-field instinct remains irreplaceable. Reviewing the footage is not a lack of trust — it is a way of respecting the truth. Yet the truth needs a unified definition in advance; otherwise we are simply replacing one subjective opinion with another. The second angle I want to raise concerns tactics. VAR does not only affect refereeing decisions; it changes the behaviour of teams. Knowing that every action in the penalty area can be scrutinized, V-League defenders are learning to shield their arms more discreetly. Coaches train them to keep hands behind their backs when entering dangerous zones. This sounds like an improvement, but in reality it deforms physical duels: a defender who cannot raise his arm loses balance, leading to new collisions. Football becomes more technical, but also more sterile. That is a subtle trade-off few analyse. There is also the fear of error. Previously, referees could make mistakes and absorb criticism. Now, with VAR, they feel safer relying on technology, but their confidence in their own judgement erodes. In many V-League matches this season, I have seen referees hesitate to call fouls inside the box, waiting for VAR to speak. This creates an awkward stutter in the flow of the game; more importantly, it changes the essence of match management. Referees are no longer the man with the scales; they have become someone waiting for technological confirmation. For the clubs, not a few have used VAR as a means of pressure. Late substitutions, players staying down repeatedly, coaches protesting violently on the touchline — all of this can create breathing space to regroup or send messages to players. VAR has inadvertently become a psychological tactic. Many V-League teams no longer hesitate to encourage controversial plays, because they know VAR will protect them if the initial decision was wrong; and if the initial decision was correct, they lose nothing. Despite all these flaws, I still believe VAR is an inevitable step. A mistake is a footnote; only silence is a verdict. When we place the microscope called VAR over our football, we will see both dust and cracks. What matters is not letting those cracks grow. Clubs, VFF and VPF need to sit together, build a more detailed technical standard for referees, strengthen FIFA-standard training, and openly explain VAR decisions the way top European leagues do. Vietnamese fans deserve to understand why a penalty was given or rejected, just as they get expert analysis on television after every match. Football is a sport of emotions, but its laws should not be a mess. An expired clause can still say more than a never-ending promise. What we need here is not something new, but a shared understanding, a clear procedure, and a consistent commitment from all parties. Fans will only trust VAR when it is fair. For me, a gatekeeper who likes to explain, that consistency is what can turn a legal text into real justice on Vietnamese pitches. Before pointing fingers at anyone, I ask myself whether I have read the whole contract. In this VAR story, I have. But I understand that reading the law is one thing; operating it in the context of Vietnamese football is a completely different story. All of us — referees, clubs, organisers, and fans themselves — are still learning to use technology wisely. Let VAR not only be a correcting tool, but a catalyst to raise the standard of match management for an entire football nation.
