Position alone is not an offence
An attacker can stand in an offside position without committing an offence. The position matters when the ball is played or touched by a teammate and the attacker then becomes involved in active play in a way covered by Law 11. This distinction explains why a player can appear beyond the defence while the match continues correctly.
The positional comparison involves the ball and the second-last opponent, not simply the last outfield defender. The goalkeeper is often one of the opponents being counted, but the law does not require that arrangement. An attacker must also be in the opponents' half, excluding the halfway line, for an offside position to arise.
Freeze the relevant moment
The key image is the moment the teammate plays or touches the ball, not the later moment when the receiver reaches it. A player can run beyond opponents after starting onside. Equally, moving back towards the ball does not erase an offside position that existed at the relevant touch if the player then becomes actively involved.
Use the current edition of Law 11 when discussing the contact moment. Under the 2026/27 wording, the first point of contact is generally used, with the stated exception for a goalkeeper's throw using the last point of contact. A paused broadcast image chosen at the wrong moment can create a convincing but irrelevant argument about position.
Look for active involvement
Playing the ball is one clear form of involvement. Interfering with an opponent can also matter, including obstructing the opponent's view or challenging for the ball. The assessment therefore requires more than checking which attacker eventually touches it. A player who never makes contact can still affect an opponent in a way relevant to the decision.
Watch the full sequence around a disputed player. Does the player prevent an opponent from seeing or playing the ball, or make an obvious action that affects the opponent's ability to challenge? Being nearby is not automatically enough. The useful question connects the player's action with the specific interference described by the law.
Distinguish deliberate play from a deflection
A touch by an opponent does not always create the same offside outcome. Law 11 distinguishes deliberate play from a deflection or deliberate save. The judgement considers control and the opportunity to pass, gain possession or clear, rather than treating every attempt to reach the ball as proof of a controlled play.
Look at the distance, speed and unexpectedness of the incoming ball, along with the time available to coordinate the action. A poor execution can still be deliberate play, while an instinctive limited contact can be different. Avoid deciding from the mere fact that the defender's foot touched the ball. The nature of that touch is the issue.
Remember the direct-receipt exceptions
There is no offside offence when a player receives the ball directly from a goal kick, throw-in or corner kick. The word directly matters. A later teammate touch creates a new moment to assess, so the exception should not be stretched across an entire attacking phase. Watch where the ball came from and what happened before the receiver became involved.
For a disputed call, work through the sequence in order: restart, teammate touch, position and involvement. This method keeps separate questions from becoming one argument about a single frame. It also leaves room for the actual officials' view and the competition's technology, rather than assuming a television angle alone provides every detail required for a precise decision.
