Pardew is keen to bolster his attacking options this summer and has confirmed the club's interest in Lyon's Bafetimbi Gomis, Aston Villa forward Darren Bent and Queens Park Rangers' Loic Remy.
Despite ongoing talks with transfer targets, Newcastle have so far failed to bring in a new forward and Pardew admits they will only do a deal if it is right for the club.
"I m not concerned about any of them slipping away," said Pardew.
"I think that we are in the market still.
"We will pay what we think is the right price."
Pardew added: "We have always managed to get somebody over the line. I think we will this time."
Asked if the likes of Gomis and Bent remain on the shortlist, Pardew noted: "They are all very much on the radar.
"We will pursue them until we get them."
