Inter Toronto FC head coach Mauro Eustáquio has thrown his support behind Arsène Wenger’s revolutionary daylight offside rule, saying the controversial change is already reshaping the game and forcing both attackers and defenders to rethink their approach.
The Canadian Premier League (CPL) became the first professional football league in the world to trial the former Arsenal manager’s proposed offside rule for the 2026 season, placing Canada at the centre of one of football’s biggest ongoing debates.
Under Wenger’s proposal, an attacker is considered onside unless there is clear daylight between them and the last defender, a significant departure from the traditional interpretation that has governed the sport for decades.
Speaking exclusively to SportsBoom.us, Eustáquio admitted the transition has required an adjustment period for players and coaches but believes the rule is producing positive changes.
“I think there is an adjustment, but I think a lot of it has to do with passing confidence to both sides of the goal,” Eustáquio said.
The Inter Toronto boss explained that defenders are now more cautious when holding a high line because attackers have greater freedom to position themselves close to the defensive line without being flagged offside.
“As a defender, with the new daylight offside rule, they’re a little bit more hesitant. They’re always onside,” he said.
“They’re thinking, ‘How can I protect myself? How can I protect the goal? How can I keep clean sheets?’ Naturally, they are thinking about just dropping down the lines.”
On the attacking side, Eustáquio believes players are embracing the opportunities created by the rule.
“Players are like, ‘Well, I’m going to be closer to that end line. I’m going to be asking for balls behind the backline.’ It’s just finding a balance of what the team wants, what the team needs, and then just sticking to it.”
Attackers Hold the Advantage
While the rule was designed to encourage attacking football, Eustáquio acknowledges that forwards currently enjoy a slight edge over defenders.
“The reality is, yes, the attackers can cheat, can be onside, and it’s a little easier for them to be onside with our defensive line,” he explained.
However, he insists teams must adapt collectively rather than complain about the changes.
“It can’t be one rule for our defenders, and it can’t be another rule for our attackers. Everybody just has to think the same way, and I think we’ve dealt with that quite positively.”
Interestingly, despite concerns that the rule would trigger a flood of goals, the CPL has yet to experience a dramatic scoring boom. Through the opening weeks of the season, most matches have remained competitive, with only a handful producing high-scoring results.
High Pressing: The Best Defensive Response
The tactical implications of Wenger’s proposal have become a major talking point among coaches, and Eustáquio believes the answer lies in aggressive pressing rather than retreating deeper.
“The reality is that the way we find the best way to counter that, the best way to be an exciting team, is to stop the ball from travelling,” he said.
“You do that by being a high-tempo, high-pressing team, pretty much full field, and especially when the opposing team is in their end.”
According to Eustáquio, the new offside interpretation is introducing fresh tactical layers to the sport while demanding greater collective discipline.
“It brings other strategies to the game. It brings other intensities to the game, but I think it’s just passing on a message to the team on how we’re going to deal with this and making sure that everybody’s on the same page.”
Technology Also Under the Spotlight
Alongside the daylight offside rule, the CPL has also implemented Football Video Support (FVS), a system that allows coaches to request video reviews of key decisions.
The technology, previously tested at the FIFA U-20 World Cup, is aimed at improving decision-making while maintaining the flow of matches.
Although still in its early stages, Eustáquio believes the benefits outweigh any potential drawbacks.
“The more you watch a slow-motion video, the more doubts you can create, so it can be tricky,” he said.
“But these tools are made for the game to have more fluidity and, at the same time, for it to have correct decisions. I think it’s extremely positive.”
With football’s governing bodies gathering ahead of the 2026 FIFA World Cup, the CPL’s experiment is likely to be closely monitored. If successful, Wenger’s daylight offside rule could become one of the most significant changes to football’s laws in modern history.
