Expected Goals definition
Expected Goals (xG) is a probability metric that estimates how likely a shot is to be scored based on historical outcomes of similar chances. Most xG models use features such as shot location, angle, body part, assist type, and sometimes game state to assign each shot a value between 0 and 1. Summed over time, xG estimates how many goals a player or team would be expected to score from the quality of chances created, making it a cornerstone of modern football analytics.
How analysts use Expected Goals
xG is widely used to separate sustainable performance from short-term variance. Comparing goals to xG can indicate overperformance (finishing hot streak) or underperformance (poor finishing or strong goalkeeping faced). For player scouting, xG per shot helps evaluate shot selection and chance quality, while xG per 90 helps evaluate how frequently a player gets into dangerous scoring positions. For tactical analysis, xG can validate whether a team's style is generating consistently high-quality chances or relying on low-probability shots. Because xG models vary across providers, the best comparisons use the same model for all players and seasons, and analysts often supplement xG evaluation with shot maps and video review to understand the tactical origins of chances.
