Sweden's VAR Drama: The Goal That Changed Everything
Sweden’s fourth goal against Tunisia on Sunday night will not be remembered for its beauty. It will be remembered for a spike on a screen.
Mattias Svanberg had been on the pitch for barely 18 seconds when he swept in Yasin Ayari’s free-kick during Sweden’s 5-1 World Cup win. The assistant’s flag went up, the stadium paused, and Tunisia breathed again. Offside. Routine.
Then the routine fell apart.
Sweden’s players surrounded the referee, their bench demanding a second look. The VAR team went to work, not just with lines and angles, but with something borrowed from another sport entirely: a football version of cricket’s Snickometer.
On first viewing, Alexander Isak seemed to have made no contact as Ayari’s delivery flashed past his outstretched boot. Svanberg, beyond the last defender when the free-kick was struck, looked clearly offside. That was the picture the naked eye painted.
The ball, and the chip inside it, told a different story.
The Trionda match ball, produced by Adidas for this World Cup, carries a microchip that logs every touch in real time. As the replays rolled, a flat waveform appeared on the VAR screen. As the ball passed Isak’s foot, the line suddenly jumped. A tiny spike. The faintest touch.
That contact changed everything. When Ayari hit the free-kick, Svanberg was offside. By the time Isak brushed the ball, Svanberg had drifted back into an onside position. Law, data and timing all aligned. The original offside was wiped out. Goal given.
“It is a good finish by Svanberg, but I can understand why the Tunisian players will be disappointed because when you look at it, it didn’t look like there was a touch,” said former Republic of Ireland striker Clinton Morrison on BBC Radio 5 Live. “It must have been the slightest touch off the outside of his right boot. Credit to VAR, credit to the referee. They got it spot on.”
For Tunisia, the decision cut deep. For the officials, it was a showcase of where football is heading.
Cricket’s tool, football’s verdict
Snickometer – or “Snicko” – has long been part of cricket’s decision-making armoury, used to determine whether a batter has nicked the ball. It works by marrying slow-motion video with an audio-visual waveform that spikes when bat meets ball.
In football, the principle is similar, but the hardware has moved on.
Adidas’ Connected Ball Technology, embedded in the Trionda, tracks every touch with boot or hand and beams that information straight to the VAR team in real time. The company says it “enables faster in-game officiating decisions and more insight into gameplay than ever before.” In practice, it gives officials something players and fans often don’t have in the moment: certainty.
When Svanberg’s goal was under review, the replay didn’t just show Isak’s leg swinging through thin air. It showed that decisive spike on the sensor feed as the ball brushed his boot. What the cameras struggled to prove, the microchip nailed.
This isn’t experimental. The same technology sat at the heart of several major calls at recent tournaments.
At the 2022 World Cup in Qatar, it settled a debate between two of Portugal’s biggest stars. Bruno Fernandes’ cross drifted towards Cristiano Ronaldo against Uruguay, nestled into the net, and Ronaldo wheeled away claiming the slightest of headers. The data said otherwise. The ball’s internal sensors detected no touch from Ronaldo, awarding the goal to Fernandes and ending the argument in seconds.
At Euro 2024, Belgium felt the sting of the system. Romelu Lukaku thought he had levelled against Slovakia, only for a Connected Ball review to show a handball by Lois Openda in the build-up. The goal disappeared, the evidence irrefutable.
From Snickometer to UltraEdge – and beyond
Cricket got there first, but even there, the original Snickometer is already on the way out. Invented by English computer scientist Allan Plaskett in the mid-1990s, it became a staple of TV coverage and the Decision Review System, breaking down replays frame by frame and overlaying a waveform to show any contact between bat and ball.
It still operates in Australia and New Zealand, but no longer features in Tests in England, where UltraEdge – a more advanced, higher-frame-rate system – has taken over. Snickometer runs at 340 frames per second, a level that now looks modest beside the precision of modern ball-tracking and connected-ball tech.
Even in cricket, reliance on Snicko has eased as newer tools arrive. Its limitations were brutally exposed during the 2025-26 Ashes, when Australian batter Alex Carey survived a review on 72 in the third Test after what was later described as “human error” by the system’s operators. Carey went on to make 106 in Adelaide. Technology can be cutting-edge; it still needs people to run it flawlessly.
Football’s version, powered by the microchip inside the Adidas ball, pushes the concept further. There is no need to sync sound with pictures or guess from a faint noise. The ball itself reports every touch. It doesn’t care who is celebrating or protesting.
On Sunday night, that silent witness spoke for Isak. It turned an offside flag into a fourth goal, left Tunisia furious, and handed Sweden another data-driven decision in their favour.
The question now is not whether this technology will stay in football, but how far it will go – and how many more games will swing on the smallest spike on a screen.
