Andy Morrell has warned Wrexham's new owners that the hard work has only just begun to secure the club's future.
The Wrexham Supporters' Trust finally completed the deal to buy the club on Wednesday after satisfying the Football Conference's stringent rules.
Player-manager Morrell said the priority for the Trust is to renew player contracts and to give him and his assistants formal deals.
"That's all going to cost money so it's a difficult situation," said Morrell.
The Trust has been waiting since September for formal approval from the Conference to take over the financially troubled club.
The delay held up the process to appoint a successor to Dean Saunders as manager, who left in September to join Doncaster Rovers.
Morrell took over on a part-time basis before being appointed until the end of the season in late October.
The 37-year-old agreed to take the job without a contract, with his coaching team of Billy Barr and Michael Oakes in a similar situation.
Morrell has not been given any money to strengthen his small squad and he fears an exodus during the January transfer window unless his players are offered extended contracts.
"Everything team-wise is good at the moment," he said, before Wrexham beat Darlington 2-1 to return to the top of the Blue Square Bet Premier table.
"The problems will arrive in January when people try to steal my players.
"There are players here that people are watching closely and I have to try to keep them here.
"It's going to be difficult because in January some of them [out of contract at the end of the season] can speak to anyone they want."
Morrell hopes to sit down with the Trust early next week to discuss their plans for the club, but he welcomed the end of the uncertainty of recent weeks.
"Finally they've managed to get it through, just in time as well to pay the players, which is for me the most important thing," he added.
"I'm just delighted. A lot of hard work has gone into it but I think a lot of hard work is ahead for them as well. So I'm pleased and looking forward to sitting down with them now."
