Pardew said: "Adebayor and a couple of others that have been mentioned. A couple more have come to light, Nicklas Bendtner is available and is somebody else that we are looking at.
"We're after somebody who would fit into our group and give us a lift. It'd be nice to see a big player come in, so we'll see."
When asked about a potential swap between Gomis and Gayle, Pardew added: "There's been no contact from either club (with regard to Gomis).
"We can give ourselves a lift so it makes sense for our fans, our players. We can improve from within, but having said that, we are trying to improve the situation."
He added: "Most of the noises on the market are probably being generated by agents and the media. It's part of the game, I quite enjoy it."
