Barnet chairman Tony Kleanthous believes Lawrie Sanchez can help mastermind their bid to beat the drop.
Former Northern Ireland manager Sanchez has joined the Bees in a consultancy role to assist rookie caretaker boss Giuliano Grazioli for the remaining four games of the season.
Kleanthous said: "We are fighting all the way and doing what we can to preserve our league status, and Lawrie Sanchez provides top-quality help."
Barnet were beaten 2-0 by Bury on Saturday in Grazioli's first game in charge following Martin Allen's departure to Notts County.
The Bees are currently three points behind third-bottom Burton, who play their game in hand against Bradford on Tuesday night.
