Positions are as each match started. A crew member the source never recorded shows as “???”; a dash means the position was not used in that match.

Includes at least one match with a substitution involving the named official. Appearances are credited by starting position; cards are credited to the official who issued them, so the two can differ.

This match had a mid-match referee substitution.

This website’s default convention is for yellow card counts and per-match averages to exclude yellow cards which triggered a player’s expulsion for receiving a second caution in the same match. When this toggle is active, those values are adjusted to include such yellow cards.
