The Key Match Incidents panel began in 2023-24, after this career, so none of these matches were reviewed by it — there is no error record to show, which is not the same as a clean one. Everything below is a count: RefCard publishes errors, not an accuracy percentage, because no source publishes the denominator such a figure would need.

Confirmed errors are only available from 2023-24, when the Key Match Incidents panel began. Earlier seasons show the disciplinary record only. ‡ Penalties are recorded from 2023-24 onward; a dash means the figure was never collected for that season, not that none were given.

The W–D–L is the club's. Nothing here is evidence of bias — a difference this size is what chance looks like. See how that was measured.
