    xG (Expected Goals)

    Analytics

    A metric measuring the quality of goal-scoring chances. Each shot is given a probability (0–1) of resulting in a goal based on factors like distance, angle, and assist type.

    xA (Expected Assists)

    Analytics

    Similar to xG but measures the likelihood that a pass will lead to a goal. A high xA indicates the player frequently creates quality chances.

    Clean Sheet

    Defence

    When a team concedes zero goals during a match. A goalkeeper or defence is credited with a clean sheet.

    Assist

    Attack

    The final pass or action that leads directly to a goal being scored. Credited to the player who provides the pass.

    Hat-trick

    Attack

    When a player scores three goals in a single match. A 'perfect hat-trick' includes a goal with the left foot, right foot, and head.
