VAR in football: explained

It was the call that stunned the world’s best referees. With the World Cup match between France and Senegal goalless in the 58th minute, Kylian Mbappe went down under a challenge from Sadio Mane inside the box. Referee Alireza Faghani was sent to the pitchside monitor, appeared to point to the penalty spot, then instead gave a goal-kick, explaining that Mbappe had initiated the contact. Darren Cann, the 2010 World Cup final assistant referee, said his phone blew up with messages from top referees who couldn’t understand why a penalty wasn’t given. Alan Shearer called it “bizarre”, Pat Nevin labelled it a “rubbish decision”. France won 3-1 anyway, but the incident reignited a familiar debate: why does a system designed to eliminate clear errors still produce such controversy?

At its heart, VAR – the Video Assistant Referee – is a system of backup officials who review decisions using video footage. In football, it was introduced to correct “clear and obvious errors” in four match-changing situations: goals, penalties, direct red cards, and mistaken identity. The referee can either review the incident on a pitchside monitor or rely on the VAR’s recommendation. In the Mbappe case, Faghani used the monitor but interpreted the contact differently from most observers. The VAR team had recommended an on-field review, but the final decision always rests with the referee.

The idea of using video to aid officials is not new. Cricket’s Decision Review System, tennis’s Hawk-Eye and rugby’s TMO have been in place for years. Football, resistant to interruptions, finally adopted VAR after high-profile errors at World Cups and in domestic leagues. The Premier League introduced it in 2019. The system uses multiple camera angles, including super-slow motion, to help officials spot fouls, offsides and other infringements that might be missed in real time. But despite the technology, interpretation remains human, and that is where the Mbappe decision sits: a matter of judgement, not a factual error.

For UK readers, VAR is a constant talking point. The Premier League has seen countless controversies, from marginal offsides to disputed penalties, and fans often feel the system disrupts the flow of the game without delivering justice. The 2026 World Cup incident shows that even with the world’s best referees on the pitch and in the booth, disagreement can persist. Former Scotland winger Pat Nevin, commentating for BBC Radio 5 Live, said the explanation that Mbappe initiated contact was “the most nonsensical line I have ever heard”. France boss Didier Deschamps diplomatically said the referee is always correct, but added that a penalty should have been awarded. The incident underscores that VAR does not eliminate subjectivity – it simply moves the point of argument.

Q: How does VAR actually work? VAR involves a team of officials watching multiple camera feeds in a video operation room. They check every potential clear and obvious error in four categories: goals, penalties, direct red cards, and mistaken identity. The VAR can recommend an on-field review, but the referee makes the final call.

Q: Why are there still mistakes if we have video replays? Not all decisions are factual; many involve interpretation. A tackle can look different in slow motion, and two people can disagree on whether contact was enough to cause a fall. VAR is designed to correct obvious errors, not to re‑referee the game. In the Mbappe case, the referee judged that Mbappe initiated contact, a view many experts rejected.

Q: What is the “clear and obvious” standard? It means the VAR should only intervene if the referee made a clear mistake. If the decision is arguable either way, the on-field call stands. This threshold is meant to limit disruptions but often leads to frustration when fans and pundits see what they believe is a clear error.

What happens next? FIFA and football’s lawmakers, the IFAB, continue to tweak VAR protocols. After a World Cup, there is always pressure to refine the system – for example, by improving communication of decisions to fans in the stadium or by allowing referees to explain their reasoning more clearly. The Mbappe incident will likely feature in post‑tournament reviews. But the fundamental tension remains: technology can help, but it cannot make human judgement disappear.
