Alejandro Díaz made history without realising it. The Pacific FC striker scored the first goal ever attributed to the so-called daylight offside rule during a 2-2 draw with the Halifax Wanderers. His left-footed volley, which opened the scoring, was later confirmed as onside under the new interpretation being trialled in the Canadian Premier League (CPL).
What Is the Daylight Offside Rule?
The rule, long advocated by Arsène Wenger, now Fifa's head of global development, deems a player onside as long as any part of their body—even a trailing foot—remains level with the second-to-last defender. This is a significant departure from the current global standard, where attackers cannot be even an inch ahead of that defender. Wenger believes the change will make the game more open and exciting by reducing marginal offside calls that frustrate players and fans alike.
CPL's Bold Trial
The CPL introduced the daylight offside rule in early April for its eighth season, with Fifa's backing. Commissioner James Johnson, a former professional footballer and Fifa executive, sees the trial as a way to simplify one of soccer's most complex rules. "Even for sophisticated football people, [offside] is a complicated rule," he said. "Plus, giving attacking players an edge has its benefits. There's more goals, and that's what fans like."
Johnson has also implemented other innovations to speed up play, including 10-second limits on substitutions and five-second countdowns for throw-ins and corner kicks. Additionally, the trial includes Football Video Support (FVS), granting head coaches two video review requests for clear and obvious errors in match-changing incidents such as red cards, penalties, or disallowed goals.
Reactions from Players and Coaches
Díaz, the CPL's all-time scoring leader, is a fan of the rule. "I love the rule because it gives you a little more advantage to score," he said. "I don't know for defenders, but for me, it's a good rule." Mike Sweeney, a former Canadian international, is also supportive: "We don't watch soccer games for referees to pull back goals because somebody's shoelace was ahead of a guy. That's not the intent of the rule."
However, defenders are less enthusiastic. Thomas Meilleur-Giguère, a veteran centre-back for the Wanderers, lamented the loss of the tactical nuance: "There's an art to being on the same line as a back line and stepping at the right moment so your opponent is offside, and now you're losing that. It changes everything I've been working on for the past 11 years as a pro."
Global Implications
While Fifa President Gianni Infantino has expressed support for an offside overhaul, the International Football Association Board (Ifab) remains noncommittal. Costa Smyrniotis, CPL's executive vice president of soccer, acknowledges the challenges but embraces the trial: "Through a trial, you're going to realise certain things that you thought were going to be correct, others maybe not so much, and we can adjust. Ultimately, it's Fifa's trial."
One month into the season, the daylight offside rule has not yet led to a flood of goals, with Díaz remaining the only player to benefit directly. However, FVS has already influenced several matches, resulting in penalties, disallowed goals, and a belated sending-off. The CPL's willingness to experiment has sparked global debate, with many watching closely to see if Wenger's vision becomes the future of soccer.
