Football, or soccer as it is known in some parts of the world, is a game played between two teams of 11 players each. It is the most popular sport globally with over 4 billion fans. As one of the simplest sports in concept, the objective is to score more goals than the opponent by getting the ball into their goal net. However, football has many intricate rules and regulations that teams must abide by. One such rule that often confuses new fans is the offside rule. This article will provide an in-depth explanation of what constitutes offside in football along with visual examples to improve understanding.
The Basics of the Offside Rule
The main purpose of the offside rule is to prevent goal hanging. Goal hanging refers to when offensive players wait near the opponent’s goal waiting for long balls to be played forward to them. This results in a boring match with minimal buildup play. The offside rule encourages clever buildup play and prevents cherry-picking easy goals.
The offside rule states that a player is in an offside position if they are closer to the opponent’s goal line than both the ball and the second to last opponent. Being in an offside position is not an offence in itself. The player must be involved in active play for an offside offence to be called.
There are two situations where a player is penalised for being offside:
- When they receive the ball directly from a teammate who plays a forward pass.
- When they are in the opponent’s half of the field and interfere with play in an offside position when the ball is played by a teammate.
The offside position is judged at the exact moment the ball is played forward by a teammate, not when the player receives it. So a well-timed run can avoid an offside call. Now let’s look at some examples to understand these basics.
Offside Technicalities and Exceptions
While the basic offside rule is simple in theory, refereeing it during a match can be tricky. There are many technical aspects and exceptions that come into play.
Moment of Pass vs Moment of Reception
As mentioned earlier, a player’s offside position is judged against the second to last defender and ball at the moment the pass is made by his teammate, not when he receives it. Late runs can avoid offside if timed correctly.
Deflections and Rebounds
If the ball takes an unintended deflection off a defender, the offside rule is calculated from the first point of contact by the teammate. The same applies to rebounds off the goal post or goalkeeper.
Set Plays
Offside rules do not apply for stationary plays like throw-ins, corner kicks, goal kicks, or free kicks. Players cannot be penalised for being in advance of the ball at the taking of these set plays.
After an Opponent’s Deliberate Play
If an opponent deliberately plays the ball like an intentional pass or clearance, the offside position is recalculated from their touch. The teammate cannot be penalised if behind the ball after the opponent’s deliberate play.
Not Interfering
If a player in an offside position does not interfere with play in any way, play should continue. Examples are running away from the ball or standing motionless away from the action.
Defender Behind Own Goal Line
If a defender is behind their own goal line, they are discounted from offside considerations. The next to last outfield player is used as the offside reference instead.
These technical points are applied at the referee’s discretion based on their interpretation of active play and interference. Now let’s look at scenarios where offside should not be called.
When Offside Should Not Be Called
Despite being in advance of the ball and opponents, there are some situations when a player should not be called offside:
- Receiving the ball directly from a corner kick, throw-in, goal kick, or free kick.
- If level with the second to last defender or behind the ball when it is played by a teammate.
- When the ball rebounds off a goal post, crossbar, or opponent without intent.
- Running back onto own half from an offside position.
- If obstructed from getting back onside by an opponent.
- When standing in an offside position but not interfering with play.
- If the ball is an unintended deflection off an opponent.
- After a deliberate save or pass by an opponent.
- When a defender steps behind their own goal line.
The crucial factor is whether the player interferes with active play from their offside position. Let’s recap the key points so far:
How to Avoid Being Caught Offside
Being caught in an offside position can ruin many promising attacks. Strikers and forwards need to time their runs wisely. Here are some tips to avoid falling offside:
- Stay level or behind the ball – Don’t move beyond the ball when a teammate has possession.
- Time forward runs – Delay forward motion and watch for the pass being made before making a run.
- Play on the shoulder – Position yourself on the edge of staying onside without going beyond defenders.
- Keep peripheral vision – Use quick side glances to read the field and defender positions.
- Read cues from teammates – Understand spacing and anticipate the pass direction.
- Communicate intentions – Let the passer know your planned run to coordinate the timing and angle.
- Practice drill routines – Repeat drills to master timing of curving runs to stay onside.
With practice, talented attackers learn to time their runs to maximum advantage by staying narrowly onside as the pass is made. Now let’s look at how technology aids offside decisions.
How Technology Assists Offside Calls
With offside decisions often made in split seconds, human errors in judgement are common. To augment decision making, various technologies have been introduced:
Goal-Line Technology
Magnetic sensors in the goal communicate within a fraction of a second if the ball fully crosses the line. This helps determine offside in tight calls.
VAR System
The Video Assistant Referee uses slow-motion replays from multiple angles to review offside decisions. This reduces incorrect human judgement calls.
Automated Offside
Artificial intelligence tracks players’ limbs in 3D to definitively determine their exact position relative to defenders. This automates offside calls with greater accuracy than human vision allows.
While assistant referees still flag initial offside calls, technology has enhanced decision making accuracy and confidence. With some teams placing their entire defensive line close to offside limits, using tech aids is a sensible approach.
As a result, understanding offside in football is a relatively simple matter. Whenever you are watching a football match, you can now tell if a player is offside when he or she is on the pitch.
