  Sussex have reshuffled their coaching set-up following relegation from Division One last season and cricket manager Mark Robinson's appointment as head coach of England Women.
  Mark Davis was appointed head coach in November, with Keith Greenfield named director of cricket and Carl Hopkinson now academy director.
  Davis said he was "thrilled" to see former Zimbabwe international Goodwin, who left Sussex at the end of 2012 to join Glamorgan, back at Hove.
  "I am confident Murray's relentless approach to batting and his technical expertise will be of great value," Davis added.
  "He has a brilliant work ethic and a passion for teaching the game, which is a vital ingredient in any elite coach."
