In a group stage match of the 2026 FIFA World Cup, Portugal defeated Croatia 2-1, securing their place in the preliminary quarter-finals. In this game, the video assistant referee (VAR) system and new technological developments played a decisive role, rather than the players themselves.
Match Development and Goals
Croatia started the game confidently when Ivan Perišić scored after a superb cross from Josip Stanišić, giving the team an advantage. In response, Portuguese captain Cristiano Ronaldo equalized with a penalty. This was Ronaldo's first goal in the World Cup playoffs.
As the match approached extra time, Portugal's coach Roberto Martínez made a tactical decision, substituting Ronaldo for Rúben Neves. This exchange proved effective: Gonçalo Ramos scored with a header following an accurate cross from Rafael Leão, increasing Portugal's lead to 2-1.
Controversial Moment and VAR Intervention
After this, Croatia intensified its play. In the 103rd minute, Ivan Perišić delivered an excellent cross into the penalty area, which Josko Gvardiol headed in. The assistant referee did not raise the flag, and Croatian players and fans began celebrating, believing the match would go into overtime. However, VAR soon began reviewing the entire episode.
The analysis revealed that forward Igor Matanović barely touched Perišić's cross. This touch was almost imperceptible on television replays, but the Adidas Trionda ball used in the 2026 World Cup recorded this contact. The new technology, a motion sensor embedded in the ball, records data on every touch in real-time. The sensor confirmed that at the moment of contact, Mario Pašalić was in an offside position. Subsequently, Pašalić passed to Gvardiol, who scored the goal. Since the offside began with this touch, VAR recommended disallowing the goal.
Technology and Team Reaction
After the goal was disallowed, Croatian players approached the referee, loudly protesting the decision. Many players argued on the field. Although it was unclear from television replays whether Matanović touched the ball, VAR had data from motion sensors and semi-automated offside technology upon which the decision was based.
The new technology, being used for the first time at the 2026 World Cup, is compared to the snickometer in cricket, although the operating principles of these technologies are different. In cricket, the microphone is used to detect contact between the bat and the ball, whereas the motion sensor in the FIFA smart ball records every touch and the slightest change in the ball's direction. It was with this technology that VAR made a decision that was almost impossible to discern with the naked eye or during a normal replay viewing. For Croatia, this was a serious blow. At the same time, Portugal, having won 2-1, advanced to the Round of 16, where they will face World Cup champion Spain.
