The daylight offside rule deems a player onside as long as some part of their body is in line with the second-to-last defender. The change is intended to increase scoring opportunities and reduce the fine-margin offside calls that have frustrated players and fans. According to The Guardian - Football, Pacific FC striker Alejandro Díaz described the rule as giving attackers an advantage. Former Canadian international Mike Sweeney told the same outlet he was fully in favor of the pilot, arguing that goals should not be disallowed for marginal offsides. Critics, however, say the daylight offside law gives a big advantage to attackers and will force teams to drop back and defend more cautiously. The rule represents a fundamental shift from the current interpretation, where any part of the body that can score a goal being ahead of the defender results in an offside, and its proponents believe it will lead to more exciting, attacking football.
The Canadian Premier League is the world's first professional soccer league to pilot the daylight offside rule, according to multiple reports. The trial was introduced in early April at the start of the league's eighth season and will be used throughout the 2026 campaign. CPL commissioner James Johnson told The Guardian - Football that the trial aims to bring clarity to the offside rule and increase goals. The league's decision to implement the trial came after discussions with FIFA and other stakeholders, and it is being closely watched by the global football community as a potential model for future rule changes.
I love it. It gives us attackers an advantage.
FIFA's Arsène Wenger has long advocated for the daylight offside rule to increase scoring opportunities and reduce fine-margin offside calls. FIFA president Gianni Infantino has also expressed support for an offside overhaul, according to major media reports. However, the International Football Association Board has shown skepticism about the daylight offside rule, and the proposal failed to win support from European football officials, research indicates. Wenger, who serves as FIFA's chief of global football development, has argued that the current offside law is too punitive and that the daylight rule would restore the original intent of the offside law, which was to prevent goal-hanging rather than penalize attackers for marginal gains.
The current offside law in most competitions sees attackers judged offside by a slew of cameras for extremely small margins, often called 'armpit' or 'toenail' offsides. The Premier League, for example, uses semi-automated offside technology with a tolerance level of about 5 centimetres. Díaz's goal would have been ruled out by leagues following the standard IFAB Laws of the Game, according to research. The contrast between the daylight rule and the current system highlights the ongoing debate about the balance between precision and the spirit of the game, with some arguing that technology has made offside decisions too clinical and detached from the on-field experience.
This trial is about bringing clarity to the offside rule and increasing goals.
If the trial in Canada is deemed a success and proves popular, Wenger's daylight plan can be written into The Laws of The Game, requiring a vote by at least two of the four British federations at the annual IFAB meeting. The specific criteria for determining the trial's success have not been confirmed, and it remains unclear how players, coaches, and fans are reacting to the rule in practice beyond the initial goal. The exact timeline for IFAB to consider adopting the rule if the trial succeeds is also unknown, as is how the daylight offside rule would interact with VAR or semi-automated offside technology. Additionally, questions remain about whether other leagues will follow the CPL's lead and conduct their own trials, and how the rule might affect defensive tactics and overall match dynamics in the long term.
