Goal-line technology: 250,000 pounds per stadium and one loud mistake

Goal-line technology does not replace the referee. It helps decide whether the ball crossed the goal line in full. The International Football Association Board (IFAB), the body that sets the laws of the game, officially approved its use in July 2012. The rules changed to allow the system, but did not make it mandatory.

Permission rather than obligation had a specific reason: cost. When the Premier League decided to install the system at all twenty top-flight stadiums before the 2013/14 season, each club had to pay FIFA 15,000 pounds for installation, testing, and the "FIFA quality seal." The total cost for one venue was estimated at around 250,000 pounds. FIFA charged an additional 15,000 for every subsequent match. That is why goal-line technology is used only at the highest level of competition.

The first decision and the mistake

The first goal in the English top flight awarded unambiguously thanks to the system was a strike by Edin Džeko for Manchester City. The history also recorded a failure. In the Blackburn vs Blackpool match, Yuta Nakayama lobbed the ball over the goal line before Daniel Grimshaw could clear it. The system did not report a goal. The referee did not award one, and the match ended 0:1. The English league issued a statement the next day: the referee's decision is final, and the result stands.

This situation shows the core problem with measurement systems. The technology does not "tell" the referee what to do. It provides a reading, and the decision remains human. If the reading is wrong or incomplete, the official makes the wrong call with full confidence that he is acting in line with the technology.

Different leagues, different systems

Rollouts were uneven. The German Bundesliga adopted goal-line technology from the 2015/16 season and chose the cheaper Hawk-Eye system, rejecting two German technologies. Ligue 1 introduced the GoalControl system in the same season and switched to Hawk-Eye in 2018.

Earlier experiments were not convincing. Tests of a ball with an implanted microchip, which was supposed to send a signal to the referee after crossing the line, were already conducted at the Under-17 World Cup in Peru. Sepp Blatter, then FIFA president, said the evidence was not clear. In 2012, the Hawk-Eye system operated at a Hampshire Senior Cup match at St Mary's Stadium in Southampton, but only in research mode: the readings went to an independent FIFA testing agency, not to the referee.

Criticism was not only about the technology. It was argued that the solution is too expensive for smaller and poorer federations.

Twelve years after the IFAB decision, the picture is mixed: measurement works where the money is, and disputed cases still happen. It is an instructive precedent for all later systems, from semi-automated offside to ball tracking.
