Derby County manager Billy Davies has recruited two more backroom staff who worked under him at Preston North End, reports BBC Radio Derby.
Julian Darby moves to Pride Park as first team coach, while Glyn Salmon is joining as assistant academy director.
The pair handed in their resignations at Deepdale earlier this month, along with Peter Williams and Kevin Thelwell.
Since then, Williams has joined Derby as goalkeeping coach, while Thelwell was named as the new academy director.
At the time the quartet left Preston, North End chairman Derek Shaw expressed his disappointment, claiming they had shown "very little courtesy" to his club.
