Mark Cooper wants at least two more players signed up ahead of the new season.
Forest Green have signed 11 players already so far this summer but the boss would like more additions before the League Two season kicks off at Grimsby Town on Saturday, August 4.
He said: "I think we're a centre half and midfield player short, after that ill be happy.
"I wouldn't say we're imminent but we're not far away."
"We still have a couple of weeks to go but the sooner the better for us."
A trialist did feature for Rovers, coming on midway through the second half but Cooper was tight lipped on the identity of the player.
