City's losing streak in all competitions was extended to five games after Tuesday night's 2-0 defeat to Poole Town.
But despite being encouraged by the response of his players, who produced a much improved display after Saturday's 7-3 defeat at home to St Albans City, Massey is keen to add more experience to his squad.
He revealed after Tuesday's game that a full-back is his priority and West Briton Sport understands City are interested in bringing 33-year-old former Exeter City defender Steve Tully to Treyew Road.
After being released by the Grecians during the summer, Paignton-born Tully signed for John Clarkson's Tiverton.
The ex Torquay defender, who has made more than 300 Football League appearances, has more recently been playing for Galmpton United in division one east of the South West Peninsula League.
Massey said: "I'm hoping to bring a new player in for Saturday. We've been playing with square pegs in round holes in a couple of areas.
"We've been asking boys to do a job that's not their position. I'm talking about full-backs.
"There will hopefully be at least one in and maybe another one in next week."
Despite Truro's dreadful run of recent form, Massey insists the club is making progress and he is confident their fortunes will soon improve.
He said: "If people out there think it's hard, it's not. I am very motivated and with the team developing I'm actually quite excited about what is going to be happening in the future."
Massey has also confirmed the door remains open for striker Mark Goldsworthy to prove himself at the club.
Goldsworthy was at Treyew Road on Saturday, before leaving the ground shortly before kick-off after learning he wasn't included in the squad.
Goldsworthy then travelled to St Dennis and came on as a substitute for Helston in the second half, scoring in the Blues' 6-1 win.

He began his career as a fullback with his local side Torquay United, turning professional in August 1997 and making his league debut in a 0-0 draw away to Barnet on 18 November that year. He went on to make over 160 appearances for the Gulls before being released at the end of the 2001–02 season.
He joined non-league side Weymouth in August 2002, quickly establishing himself in the side and winning the awards for Player of the Year and Away Player of the Season in 2003–2004. He lost his place in the side after the appointment of Steve Johnson as manager and asked for a transfer in January 2005.
Although he later withdrew this request, he was allowed to join Exeter City in February 2005.
However, he returned to Weymouth in May that year as new manager Garry Hill's first summer signing on a two-year deal. He returned to Exeter in January 2007 and was a regular in the side that made the play-off final at the end of that season, scoring the winning penalty in the semi-final against Oxford United. On the 2nd of July 2013 Tully was released by Exeter City. Tully is also manager of the Exeter City FC Ladies team having great success.
