World Cup chip technology overturns offside call for Sweden goal

Sweden’s 5-1 win over Tunisia at the 2026 World Cup was overshadowed by a high-tech officiating decision. Mattias Svanberg’s fourth Swedish goal was first disallowed for offside, then awarded after a VAR review used data from a microchip embedded in the ball.

Svanberg, who came on in the second half, scored 18 seconds after entering the match. He finished after a free kick by Yasin Ayari, but the assistant referee ruled him offside at the moment the kick was taken. VAR then reviewed sensor data from the match ball and concluded that Alexander Isak had made a slight touch on the ball after the free kick, which meant Svanberg had already moved back onside when the decisive contact occurred.

The contact was not visible to the naked eye, but the sensor graphic shown on television displayed a clear data spike when the ball passed Isak’s extended foot. That evidence proved the touch and confirmed the goal. The system used in the tournament is Adidas’s Connected Ball Technology, which transmits real-time information on every touch, including timing and intensity, to VAR officials.

The article compares the system to cricket’s snickometer and says similar technology has already influenced major tournaments. At the 2022 World Cup in Qatar, a Portugal goal against Uruguay was credited to Bruno Fernandes after the ball data showed Cristiano Ronaldo had not touched it. At Euro 2024, a Romelu Lukaku goal for Belgium against Slovakia was ruled out after the ball sensor detected a handball by Loïs Openda. The Sweden-Tunisia episode has renewed debate over how far such technology should shape football decisions, especially in marginal offside and touch situations.
