Former Toon boss Sam Allardyce has already recruited Modibo Maiga, who opened his account for the club in Tuesday night's 2-0 Capital One Cup win over Crewe, and Matt Jarvis this summer.
But Liverpool pair Andy Carroll and Joe Cole are still being linked with moves to Upton Park and although assistant manager Neil McDonald would not be drawn on individual targets, he confirmed West Ham were focusing their search on attack more than defence.
Neil McDonald: "The manager and the board have worked very hard to bring people in and if we could nick another one before the end it would be brilliant.
"That would bring extra competition, it would be another body which would be good for the team.
"We are scouring all over the place. If we get the right person then hopefully the chairman can pop up with the money again and get them in."
