Mark Marshall is set to become Mark Stimson's 14th summer signing after accepting Barnet's offer of a contract.
The winger, 23, parted ways with Swindon at the end of last season and will now rejoin Stimson having played under him during their time at non-league Grays.
Marshall has already passed a medical and is expected to line up in Saturday's pre-season friendly against Peterborough at Underhill.
Stimson told the club's official website: "He has pace to burn and can play on either flank.
"I consider that I have finished my squad building for the time being."
