Watch a soccer match in 2026 and compare it to the earliest footage we have, and it looks like an entirely different sport. The casual viewer assumes that’s the result of a higher quality kit, the professionalisation of the game, the freakish athleticism of the modern player, the list goes on.
Yes, these points are valid. But the rules behind the game have been just as significant in driving change. Some have been applauded and are almost impossible to think of soccer without them, and others are maligned and continue to draw heavy criticism and debate.
First Rules: Turning the Game Professional
In the early days of soccer, the game very much operated on a local level. Schools and towns each played in their own particular way, with the game differing depending on where it was taking place. In some versions, outfield players were sometimes allowed to carry the ball.
It seems almost quaint, but it made the game a bit of a mess, and it stifled growth. Officials decided that shared laws were necessary, resulting in the creation of the soccer we know today. The history of modern soccer effectively began with the implementation of the so-called Cambridge Rules, providing a framework for the game and making it a proper sport.
This important step helped boost popularity, with players now having a single point of reference. And of course, fans could now argue about matches over a pint at the pub with a proper rulebook to refer to. Of course, nowadays, that tends to happen on Reddit and X!
Offside Rule: Changing How Teams Attack
Offside has long been one of soccer’s most debated and infamous rules. We’ve seen many comedic instances in films and television where the sheer complexity of the rule is the punchline (if you ever need to explain it, here’s a refresher).
Yet without offside, the game would be completely different. Tiki Taka wouldn’t be a thing. Carefully timed runs would no longer be necessary; strikers would simply be able to camp in the opposition box. It effectively slows the game down to a near standstill at times.
And that’s really the whole point of having it. It focuses on creating a fluidity of play, based on a strong tactical framework. Building an attack requires careful orchestration, with teams looking to beat the offside trap in cohesive movements honed on the training pitch.
The offside rule, introduced in 1925, gives teams more space, reducing the number of defenders needed and making static defensive structures obsolete.
Substitutions: Squad Building and Tactical Changes
In the early days of soccer, even injury substitutions were not allowed. Now, coaches can make up to five changes during a match. Substitutions add another layer to the game, the rule allowing coaches to adapt to an opponent once the referee has already blown the whistle.
The rule was originally introduced to deal with injuries, keeping the game 11v11 and protecting players. It meant that no one is forced to continue playing to their detriment, an important factor with both ligament and head injuries, for example.
But now, substitutions are primarily used as a tactical intervention. Coaches can react to the changing requirements of a game, responding to an opponent or fixing a mistake. The tactics can be tweaked not just with formation, but with a change in personnel.
The classic is adding a speedy striker towards the end of games, coming on against worn-out defenders. Players now even specialize in coming on and having an impact. There’s even a term for it: the supersub. In the Premier League, the name that tends to come to mind is Ole Gunnar Solskjaer, who famously scored in the 93rd minute of the Champions League final.
VAR: Changing the Spirit of Soccer?
VAR (Video Assistant Referee) was introduced to combat what seemed to be a clear problem in soccer: referees making mistakes on the biggest stage. In theory, most fans and pundits agreed with modernizing the sport. After all, it seemed a bit silly to rely on the judgment of a single person on the pitch, especially with the later availability of video replays.
Yet just a few years after its implementation, the grumbling has reached fever pitch. While VAR has fixed some of the most obvious mistakes, like a ball going over the line (how Frank Lampard wishes he’d had that in 2010), a clear violent act that’s been missed, or a handball in the penalty box, many believe it’s also taken the soul from the game.
First, mistakes still happen. The debates are still as hotly contested, with fans often disagreeing with the official decision from the video referees. We still see ridiculous refereeing errors, like the Luis Diaz goal that was ruled out against Tottenham. Or the Coventry City heroics that were arguably stolen from them against Manchester United after a contentious offside call.
That’s not the biggest problem, however.
In soccer, when a goal is scored, it’s different from basketball or the NFL. Goals are rare; they’re special. When Messi finishes a beautiful attacking move, it’s an explosion of joy, a moment where all that pent-up frustration is let loose.
At least, that’s how it used to be. Now, a goal isn’t always a goal. Fans have to wait before celebrating; it’s often minutes before a goal is scored. When checks happen, fans in the stadium don’t even know what’s going on. They’re not allowed to see the replays.
The technology is rigid, but the human element is still there. At least in the video room. In the stadium, with the fans, the spirit of the spontaneous celebration has changed. And, probably not for the better.
Rules Change, Still the Same Game
Soccer rules will keep changing, for better or worse. The offside rule was once hated, but now it’s part and parcel of a standard match. Officials keep changing what’s written in the rulebook, yet the feeling when a goal is scored is just as glorious as ever (after a correct VAR check, naturally).
