Key Football Terms Explained
What is xG (Expected Goals)?
xG, or expected goals, is a statistic that measures the quality of a goal-scoring chance on a scale from 0 to 1. It estimates the probability that a shot results in a goal based on factors like distance, angle, and the type of chance. A team with a high xG created lots of good opportunities; a low xG means their chances were difficult. It has become one of the most widely used metrics in modern football analysis.
What is VAR?
VAR stands for Video Assistant Referee — a system in which officials review video footage of key incidents. VAR can be used for four match-changing situations: goals, penalty decisions, direct red cards, and cases of mistaken identity. It was introduced to reduce clear and obvious errors and has been a feature of the World Cup since 2018.
What is offside?
A player is in an offside position if they are in the opponent's half and closer to the goal line than both the ball and the second-to-last defender at the moment the ball is played to them. Being offside is not an offence in itself — it is only penalised if the player becomes involved in active play.
What is a false nine?
A false nine is a centre-forward who drops deep into midfield instead of staying high up the pitch. This movement drags defenders out of position and creates space for teammates to attack, a tactic made famous by some of the greatest attacking teams of the modern era.
