West Ham boss David Moyes has confirmed he wants to buy this month.
Moyes says the Irons are continuing to contact clubs as they search for new recruits - but warned they will not spend unless they can strike the right deal.
The east London club are expected to bring in a new striker before the window shuts after selling Sebastien Haller to Ajax for £20million.
Moyes said: "We've already made enquiries for players at clubs, it's not as if we're not trying, but I need players who can make a difference.
"If not I'll use the young players or find someone else in the squad."
