Reserve team coach Thompson is heading to Celtic and Carver’s name has already been put to Hughton.
Former Middlesbrough reserve coach Malcolm Scott is also in the frame, and he benefits from being both a free agent and a friend of United number two Calderwood.

He will be working under a new manager at Home Park next season after the Pilgrims decided to look for a new boss following sacking Paul Mariner after their relegation.
