A century‑old controversy resurfaces at the World Cup
The tournament’s knockout stages have been marred by a string of marginal offside decisions that have left coaches and fans questioning the balance between tradition and technology. England’s long‑standing rule, first codified by the English Football Association in 1863, still defines a player as offside when any part of their body other than the hands or arms is nearer to the opponent’s goal line than both the ball and at least two defenders. Yet the rise of video assistant referee systems and semi‑automated offside technology has turned those split‑second judgments into data‑driven verdicts.
Cristiano Ronaldo’s disallowed goal for Portugal and Davinson Sanchez’s similarly chalked‑off strike for Colombia illustrate how a few centimeters can decide a match’s trajectory. Croatia’s head coach Zlatko Dalic publicly lamented that VAR “kills the emotions and joy” of football, a sentiment echoed by players such as Shoja Khalilzadeh, Igor Matanovic, Mario Pasalic and Josko Gvardiol, who have all felt the sting of tight calls.
The technical backbone of these decisions relies on semi‑automated offside technology, which captures 100 frames per second and tracks 10,000 data points on each athlete’s body, while ball‑chip sensors like the Adidas Trionda help confirm whether a player has touched the ball. This precision, however, has produced an increase in marginal calls that some argue undermine the flow of the game.
In response, FIFA’s head of global development Arsene Wenger has proposed a radical rewrite: a player would be considered onside if any part of their body aligns with the last outfield defender, effectively eliminating the need for a ‘daylight’ threshold. The Canadian Premier League is already trialing this ‘daylight offside’ rule, reporting a noticeable uptick in goals scored. The International Football Association Board will study the CPL’s findings before deciding whether to adopt the change worldwide.
The English Football Association, FIFA, and the International Football Association Board continue to monitor these experiments, while the Canadian Premier League, headquartered in Canada, serves as a live laboratory for the sport’s evolving governance. As the debate unfolds, the intersection of history, technology, and fan experience remains at the heart of football’s most contentious rule.
