After he retired from refereeing at the end of the 2021–22 season, Moss became a manager at Professional Game Match Officials Limited, the body responsible for refereeing games in English professional football, until his departure in March.

“I have loved my short time at the Scottish FA and already I believe clubs, players, managers and supporters see a significant improvement under Willie’s leadership,” he added.
