QPR's Loic Remy is also on Pardew's radar.
He told the Northern Echo: "Both of those players are on our list. I make no bones about that.
"But they are under contract at other clubs. It's difficult, you have to be careful. It's nice for our fans to hear names, but I don't want to disrupt other clubs' preparations.
"We have a list of four or five strikers who will push [Papiss] Cisse, Shola [Ameobi], Adam Campbell and Yoan Gouffran because that will be important next season.
"We do need two strikers. Last year, I didn't think there was enough competition in that area for a Premier League team."
