FIFA confirms VAR correctly denied Croatia equaliser vs Portugal
Portugal beat Croatia 2-1 in Toronto on Thursday and advanced to the Round of 16 after FIFA confirmed VAR correctly disallowed Josko Gvardiol's late equaliser. Connected Ball Technology in the Adidas Trionda detected an imperceptible touch by Igor Matanovic, confirming Mario Pasalic was offside in the buildup. For fans asking who won last world Cup knockout drama, Portugal did—while Croatia left stunned by a decision no replay could clearly show.
Key Takeaways
- FIFA backed VAR's decision to rule out Croatia's stoppage-time equaliser against Portugal on offside grounds.
- Connected Ball Technology inside the Trionda ball detected a touch invisible on standard replays.
- Portugal won 2-1 in Toronto and advanced; Cristiano Ronaldo had earlier scored his first World Cup knockout goal to level the match.
- IMU sensors in the official match ball operate at 500Hz and display contact as a "heartbeat graphic" for broadcasters.
- The technology has been used at previous tournaments including the 2022 World Cup and Euro 2024.
Why Did VAR Disallow Croatia's Equaliser Against Portugal?
Croatia thought they had rescued a draw when Gvardiol scored deep in added time, but referee Espen Eskas was sent to the pitchside monitor after a VAR review. According to ESPN's reporting, replays alone could not prove that Matanovic touched Ivan Perisic's cross before Pasalic became involved. FIFA said data from the ball proved Matanovic made contact, meaning Pasalic was offside when he played the ball to Gvardiol.
FIFA posted on X that Connected Ball Technology "proven that contact was made by Croatia's #20 Igor Matanovic in the build up to the goal against Portugal, allowing the referee to correctly determine offside and disallow the goal." The call ended Croatia's tournament hopes and confirmed Portugal's place in the last 16.
How Does the Trionda Ball's Connected Technology Work?
The official Adidas Trionda World Cup ball carries a small inertial measurement unit (IMU) sensor, as AP News explained. FIFA says it operates at around 500Hz, capturing data 500 times per second to track acceleration and movement in three dimensions. The system can detect the exact moment a player makes contact, even when television angles are inconclusive.
During the Croatia review, broadcasters showed what FIFA calls a "heartbeat graphic"—a spike indicating the ball was touched as it passed Matanovic's head. ESPN compared the display to cricket's "Snicko" technology. Ball data combines with in-stadium camera tracking and is transmitted in real time to video assistants.
Similar connected ball systems were deployed at the 2022 World Cup and at the most recent men's European Championship in 2024. Debates over subjective VAR calls are exactly why Future Tech & AI Wonders coverage tracks how sensors reshape elite sport.
What Else Happened in Portugal vs Croatia?
Before the controversy, the Round of 32 clash in Toronto had already delivered historic drama. FOX Sports noted that Cristiano Ronaldo scored his first FIFA World Cup knockout-round goal, converting a penalty to put Portugal level after Croatia had taken the lead. That milestone made him the oldest scorer in a World Cup knockout match at 41 years old.
Portugal ultimately held on for a 2-1 win once the late equaliser was chalked off. Croatia's players and coaching staff left devastated, convinced the goal should have stood. FIFA insisted the chip inside the ball—not human guesswork—settled the offside sequence.
Does This Set a New Standard for World Cup Officiating?
FIFA framed the episode as proof that Trionda's IMU sensors give officials "an unprecedented level of data to make fast, accurate decisions." Croatia's painful exit shows the flip side: a touch too faint for the naked eye can still rewrite a knockout result. As semi-automated offside and ball tracking merge, the gap between human perception and machine certainty may only widen.
