Croatia’s Disallowed Goal vs Portugal: The Role of Connected Ball Technology in the Offside Decision
Portugal, one of Europe’s top contenders at the 2026 FIFA World Cup, narrowly defeated Croatia 2-1 thanks to a late goal from Goncalo Ramos. The match, intense and tightly contested, almost saw a dramatic equalizer for Croatia in stoppage time.
Josko Gvardiol seemed to score a last-gasp goal that would have leveled the game. Yet, after a review, the referee disallowed the goal due to an offside ruling, leaving Portugal victorious. Here’s a closer look at why that decision stood and the technology behind it.
What Led to the Disallowed Goal?
During the 12th minute of added time, Gvardiol’s strike appeared to bring Croatia back into the match. But the officials paused play to consult video evidence. They found that Igor Matanovic had barely made contact with the ball using his head before the ball reached Mario Pasalic, who was in an offside position.
If Matanovic hadn’t touched the ball, Pasalic would have been onside based on the original pass coming from deep on the left flank. The referees had to consider whether the ball’s deflection off a Portugal defender, Renato Veiga, affected the ruling. Since Veiga didn’t deliberately play the ball but merely ducked under it, the offside call remained intact.
Connected Ball Technology Changes the Offside Review
The 2026 World Cup introduced the Adidas Trionda ball, equipped with embedded sensors known as Connected Ball technology. This tech played a crucial role in determining the validity of Gvardiol’s goal.
At first, replays gave no clear sign that Matanovic touched the ball. But the VAR team used data from the ball’s sensor to detect every touch. The system displayed a graphical waveform representing ball contact moments. A subtle spike appeared as the ball passed over Matanovic’s head, confirming a touch.
This evidence shifted the offside analysis. Because the ball was last touched by Matanovic before reaching Pasalic, who was offside, the goal was ruled out. Connected Ball technology essentially acted like cricket’s Ultra Edge, where audio waveforms help identify faint contacts.
How Does Connected Ball Technology Work?
FIFA and adidas developed this sensor-based system to improve decision-making accuracy during matches. A tiny inertial measurement unit (IMU) inside the ball captures data 500 times per second, tracking its speed, position, and touches.
The real-time information is sent to the video operation room and combined with stadium camera feeds. This enables VAR officials to pinpoint the exact moment a player contacts the ball, crucial for semi-automated offside calls and other decisions like handballs or penalty incidents.
The technology helps referees deliver faster, more precise rulings while providing fans with deeper insight into the game’s details.
Final Thoughts
The use of Connected Ball technology made a significant difference in Portugal’s narrow win over Croatia. Though the offside call sparked debate, the precise data revealed a crucial touch that otherwise went unnoticed on standard video replay.
Matches at this level often hinge on such fine margins, and the tools now available offer a new layer of fairness and clarity. We think this is just the start of how technology will continue shaping football decisions in future tournaments.
