What Is The Offside Rule In Football? Explained Simply

What Is The Offside Rule In Football?

We all wonder sometimes – what would football be without the offside rule? The bare of your life on a Saturday afternoon as the linesman lifts his flag when the striker is through on goal, or when VAR rules out a goal due to an arm or a toenail in an offside position.

However, for someone who is new to the sport or is a ‘casual’ watcher of football, knowing what is and isn’t offside can be quite a daunting task.

So, what is the offside rule and how is it in football?

What Is The Offside Rule?

What are your honest thoughts on the current offside rule?⁰Personally, I think it needs revision.⁰A player should be considered offside only if half or more of the upper body is ahead of the last defender.

It might not be the simplest rule in the book, but the offside rule in football is not too dissimilar to the rules in other sports, such as in the NFL.

Its sole purpose is to stop goal-scorers and attackers, giving an advantage to defenders by not allowing forwards to simply stand in the opposition’s box and wait to score goals. The offside rule also stretches play, encouraging defenders to push forward and play a high defensive line.

In basic terms, as an attacker, you cannot stand in front of a defender when a ball is kicked and then proceed to interfere with play – this would result in a free kick to the opposition.

Defences can choose to play a high or a low line to push the opposition's attack forward. However, the forward line must respond to this and keep the defender in front, with centre backs or full backs the closest to goal.

Comparatively, players cannot be offside from a free throw, no matter where on the pitch, and they also cannot be offside in their own half.

If a ball deflects off an opposition player or is kicked by someone who is not on the same team, they can interfere with play, despite being in front of a defender.

In recent times, controversy surrounds the offside rule, with calls and decisions becoming subjective. However, by the book and for someone who is trying to learn the rule, a flag should be raised if an attacker is in front of a defender and affects play.

What Is Arsene Wenger Attempting To Introduce?

In the 20th century, football is still an evolving game with new rules and adaptations being introduced each year. Of course, the invention of VAR was a large step into the new world of computer officiating.

However, former Arsenal manager, Arsene Wenger, has put himself on the frontline, pioneering a significant change to the offside rule, handing the attacking team an advantage.

Weekly, decisions in Europe’s top league, such as the Premier League, Bundesliga, and Ligue 1, come down to minuscules with goals being ruled out due to an outstretched hand or knee of a forward.

Wenger’s ideas will change that, being named as the ‘daylight’ offside rule, meaning that an attacker is considered to be on-side if any part of their body is with the second-to-last defender, even if their body or part of it is ahead.

Aimed at speeding up play, this new rule would decrease the number of controversial and marginal decisions, also encouraging more attacking play.

However, Wenger’s ideas would also reduce attacking movement, with attackers choosing to stand in front of the opposition’s final defender rather than running in behind.

Does The Offside Rule Negatively Affect Football For Fans?

Yes, the offside rule does take away an element of entertainment and excitement when goals are scored. However, without it, the game that we all know and love would not be the same, with the structure and scoring of games being completely different.

Games do not need to end in a cricket score, and while there are adaptations that could be made, such as Wenger’s rule.

Nevertheless, a huge and drastic change to the sport, such as taking out the offside rule, does not need to be made.

A linesman’s flag or a line drawn by someone in the VAR booth that denies your team a crucial goal might be frustrating at times, but that is football, and throughout the season, decisions often even out for each team.
