The 19-year-old has reportedly been tracked by Manchester United and Liverpool and Holloway has admitted that the attacking midfielder may move on in the January transfer window.
"I asked for no guarantees from Crystal Palace about the future of Wilfried Zaha," Holloway said in his column in The Mirror.
"Would I like to keep him with me at Palace? You're damn right I would. Players who can make a difference are like gold dust, especially in the Championship – and Wilfried is one of those.
"I've got him at least until the transfer window reopens in January and I can't wait to see him close up and in the flesh every day."
Holloway was confirmed as the new Palace manager on Saturday.
