"When we lost out on Remy it was pretty evident we weren't going to get a big striker," Pardew told the Newcastle Evening Chronicle.
"They are pretty difficult to get over the line. You look around and nobody apart from Remy has really moved - maybe Danny Graham, but I don't think he's in that level.
"I think that's something we will look at in the summer."
Newcastle now have the likes of Gouffran, Papiss Cisse, Shola Ameobi and Adam Campbell to choose from up front, but Pardew believes that any manager would want more options up front.
"You always want another striker!" he added.
"I want Man United's position - Van Persie, Rooney, Hernandez and Welbeck. That would be nice. But we haven't got that."
