Nottingham Forest have confirmed John Pemberton has re-joined the club's coaching staff as Performance Development Coach.
Pemberton initially joined the Forest set-up at Academy level before going on to take up the role of reserve manager under Colin Calderwood.
The 47-year-old left the City Ground in summer 2009 following a short spell as caretaker manager and joined Sheffield United as Academy Director.
Pemberton famously led Forest to a 3-0 FA Cup third-round victory over Manchester City.
Pemberton spent time at Rochdale, Crewe, Crystal Palace, Sheffield United and Leeds United during his player career.
