The controversial so-called “Wenger Law”, a radical rethink of football’s offside rule, will be put to the test in the 2026 Canadian Premier League (CPL) beginning in April, after being approved for trial by the International Football Association Board (IFAB).
Under the proposed rule change, an attacking player will only be judged offside if their entire body is clearly beyond the last defender at the moment the ball is played, eliminating marginal decisions based on tiny body parts such as toes or knees that have often dominated modern offside calls.
The trial, formally green-lit for the Canadian league ahead of its April–October 2026 season, marks the first time the idea will be tested in a senior professional competition. Daylight offside, as it’s sometimes dubbed, aims to reduce contentious stoppages and favour attacking play by allowing forwards to remain onside unless there is a visible gap or “daylight” separating them from the last defender.
The proposal originates from Arsène Wenger, FIFA’s Head of Global Football Development, who has championed the idea as a way to modernise one of the sport’s oldest and most debated rules. Critics, including some national associations and European leagues, initially pushed back — and there were suggestions the idea might be dropped entirely at law-making meetings this year.
However, IFAB’s approval for an official trial in Canada gives the concept a renewed chance to prove its viability. CPL’s compact structure and schedule are expected to provide a concentrated dataset, which will be closely reviewed later this year.
If the trial is judged successful, the rule could be recommended for broader adoption, potentially worldwide, in 2027 and beyond, altering one of the game’s core tactical frameworks.
Observers say the experiment could have far-reaching implications, from boosting scoring opportunities to reshaping defensive strategies across leagues, even as traditionalists question whether the change preserves the competitive balance that has defined football for more than a century.
