Derby County boss Paul Jewell has named Gary Walsh as new goalkeeper coach.
Walsh, who played under Jewell at Bradford and worked with him at Wigan, has now decided to join the 43-year-old at Derby, who are currently bottom of the Barclays Premier League.
Latics boss Steve Bruce said: "Gary has conducted himself very professionally throughout my short stay here and has behaved with integrity.
"When it became clear he wished to leave, I asked him to remain here through the busy Christmas period, and he has honoured that agreement, never giving less than his all for us.
"I understand he has been a good servant to the club in his time, and he leaves with the best wishes of everyone here."
Wigan hope to make an announcement regarding a new goalkeeping coach within the next 48 hours.
