The former Magpies keeper, who left the club after 20 years at the end of June and has since signed for promoted Hull, now regards himself as a fan and is keeping his fingers crossed that new director of football Joe Kinnear can end the club's wait for a transfer breakthrough.
Pardew is desperate for Kinnear to land him at least one, if not two proven strikers, with a loan deal for QPR's Loic Remy currently under consideration.
Harper said: "Obviously having spent 20 years here, I am a Newcastle fan and the same as everybody else, we keep an eye on it, watch it closely.
"There seem to be some positive noises about players coming in now. The likes of maybe Remy coming on loan would be a very good signing.
"As a fan, you want to see as many options as possible in a black and white shirt. I know that's what the manager wants, and hopefully he will get that."
