GRESLEY are seeking a centre-half after defender Marc Strzyzewski left the club last week.
The 31-year-old centre-half has joined Heanor Town, leaving the Moatmen with just Jamie Barrett and the returning Tom Land as out-and-out centre-backs.
John Guy and Mitch Hanson can also play there, but manager Martin Rowe is looking for more cover ahead of the big kick-off on August 16.
"We are looking to bring in more players, squad-wise," said the Moat boss.
"Losing Marc Strzyzewski was a big disappointment, but the offer from Heanor was too good to turn down. I can see why he's gone there.
"We need a centre-half, but we've got Jamie, Tom Land, and John Guy and Mitch Hanson can both play there.
"John played 15 games there last season, and we have played Mitch there in pre-season. He has looked good, but not as good as he does at full-back.
"We'll keep looking, and trying to get the right people in. But it's having the budget – and we don't.
"We might have to wait until the season kicks off and then look to get in players who aren't getting games."
Gresley have hit the goal trail in their recent pre-season games, with 4-0, 4-2 and 5-1 wins respectively against Heather St John's, Dunkirk and – on Tuesday night – Graham St Prims.
"After the first game against Solihull Moors when we weren't hitting the back of the net, we certainly are now," said Rowe.
"Obviously Brad Wells has really done well, but everybody has chipped in.
"Alex Steadman is scoring, and even Tom Land has got on the scoresheet."
Gresley have brought in eight new signings this summer, the latest being striker Ashley Robinson, signed from Ilkeston Town.
Rowe will chat to trialists Josh Wright, a striker and Russ Peel, a left-back or left midfielder this week about signing for the club.
Rob Spencer, who signed fresh terms earlier this month, is considering taking a break from football but will be available if needed.
"Rob Spencer is available if we want him, but Rob Mulonga has done really well. He may lack a bit of experience, but his pace will cause a lot of defenders problems," said Rowe.
Gresley host Ilkeston Town and Kings Lynn Town over the next two Saturdays, sandwiching a trip to Stapenhill.
"They'll be our big tests and we'll know where we are from there," said Rowe.
Gresley's only injury concerns surround midfielders Sam Grice (knee) and Mickey Lyons (ankle).
