"I haven't discussed new contracts. That will wait until the end of the season because we will have to see how the rest of the season goes," Gradi told the club's official website.
"I am in no great rush to do anything although there are one or two in the team who are out of contract in the summer.
"The budget will obviously be a factor because we are now a League Two club and we can't afford to have the budget we have had over the last few years."
Gradi added: "We certainly won't be taking a lot of 'maybe' players. We will bringing in players who are there or thereabouts and ready-made to go into the team. The rest will come through our academy."
