World Cup xG Lab
TeamsPlayersModelCoverage
StatsBomb powers the past chance-quality model and shot-location views. FBref adds recent league-form context. Understat adds club xG context. DataMB adds 25/26 percentile scouting profiles. This dashboard is not a guaranteed 2026 World Cup prediction model.

Source coverage at a glance

Missing StatsBomb data does not mean a team or player is bad. It means the open-data competitions used for the historical model do not include enough shots for them.
