Freedman has brought in four players so far and has previously admitted more signings are necessary, and he has now said that he is looking at a couple of Premier League players.
"I can understand the fans' frustration for not signing one or two names, but we're on a strict budget and we try to stick to it," Freedman told the Croydon Advertiser.
"With the contacts I've got, there's one or two lined up. We'll be looking at attack-minded players from the Premier League."
Freedman has been manager of Palace since being promoted from assistant in January last year.
