Goalkeeping Statistics: How Keeper Performance Shapes AI Match Predictions
Goalkeepers are arguably the most influential individual position in football, and their statistical contribution has become increasingly measurable through advanced metrics.
Post-Shot Expected Goals (PSxG)
Post-shot expected goals measures the quality of shots a goalkeeper faces, accounting for shot placement, speed, and angle.
Save Percentage and Shot-Stopping
Raw save percentage remains informative when contextualized properly. This adjusted metric is a stronger predictor of future clean sheet probability and match outcomes.
Distribution and Sweeper Metrics
Modern goalkeeping extends well beyond shot-stopping. Goalkeepers who excel in distribution can effectively add an extra outfield player to their team's build-up play.
Goalkeeper Absence Impact
When a first-choice goalkeeper is injured or suspended, the impact on team performance is often dramatic.
