Why Is VAR So Controversial at the 2026 World Cup?
Why VAR and offside calls keep dividing the 2026 World Cup: millimetre offsides, the Ghana penalty, Belgium's penalty against Senegal, the Kane no-call and his round-of-16 penalty against Mexico, Quansah's red card, Egypt's goal wiped out against Argentina for a build-up foul, the quarter-finals (France's three-minute penalty check against Morocco and Belgium's waved-away handball appeal against Spain), and why some decisions are factual and others a judgment call. Plus FIFA's mid-tournament switch to on-site VAR officials for the closing rounds. Now covering both semi-finals: Spain's contested Oyarzabal penalty against France, and why the "VAR never checked" claim about Messi's build-up to Argentina's equaliser against England was wrong on both counts.

Why Is VAR So Controversial at the 2026 World Cup?
Why VAR and offside calls keep dividing the 2026 World Cup: millimetre offsides, the Ghana penalty, Belgium's penalty against Senegal, the Kane no-call and his round-of-16 penalty against Mexico, Quansah's red card, Egypt's goal wiped out against Argentina for a build-up foul, the quarter-finals (France's three-minute penalty check against Morocco and Belgium's waved-away handball appeal against Spain), and why some decisions are factual and others a judgment call. Plus FIFA's mid-tournament switch to on-site VAR officials for the closing rounds. Now covering both semi-finals: Spain's contested Oyarzabal penalty against France, and why the "VAR never checked" claim about Messi's build-up to Argentina's equaliser against England was wrong on both counts. Now covering the final too: Spain 1-0 Argentina after extra time, both VAR calls quiet check-and-clears, and Enzo Fernández's second-yellow red, the turning point, left to the referee with no VAR intervention.
