The 34-year-old Scot spent the final three months of the last campaign on loan at Leeds where he scored five goals in 11 appearances to help United to the League One play-off final.
But Freedman wants to remain at Palace and see out the rest of his contract and will only look for another club if Warnock tells him he has no future at Palace.
Freedman said: "I've not spoken to Neil Warnock since the end of the season. I've heard that there's a meeting scheduled but I've not heard from the manager. As far as I know I'm still reporting for pre-season training on July 2.
"I want to stay at the club, that's for sure. If the manager turns round to me and says he wants me to fight for my place then I will do that. But if he tells me that there's no chance of me playing then I'll have to look elsewhere."
