Per 90 = total × 90 ÷ minutes; shown from 900 minutes played. Goals minus xG: positive means more goals than expected; negative means fewer. Assists minus xA compares recorded assists with expected assists. The non-penalty difference excludes penalties from both goals and xG. xG per shot = xG ÷ shots, including penalties; shown from 20 shots. It describes average chance quality, not finishing ability. Season changes compare the same club and league, adjusting for minutes, not playing conditions. Past results, not a prediction.
