David Moyes insists he is in no hurry to sell any of his misfiring strikers amid reports West Ham are open to offers for Javier Hernandez, Andy Carroll, Diafra Sakho and Andre Ayew.
The quartet have notched a paltry 11 Premier League goals between them so far this season.
Mexico front man Hernandez has cut a frustrated figure during his increasingly rare appearances in the starting line-up with Moyes preferring to play wingers Michail Antonio and Marko Arnautovic in attack since he took over in November.
But West Ham would want to recoup a large chunk of the £16 million they paid Bayer Leverkusen last summer were "Chicharito" to leave.
"I think the form of Marko and Michail has probably made it difficult," added Moyes. "When I joined -- and I've only been here nine or 10 weeks -- Javier was injured and we had to go with Marko and Michail up front and they have both done well.
"He's a really good player, his finishing ability is as good as there is anywhere, he thrives on balls in the box and maybe in a lot of games we haven't had that service to give him.
"But you'd be hard pushed to say that he would necessarily be playing in front of the other two at the moment."
Sakho, who tried to join French club Rennes in the summer only for a move to fall through, has been linked with a move to Crystal Palace.
But Moyes said: "I'm not aware of that at all. I know there has been talk of it, but Diafra is injured so I can't give an update on it.
"There has been talks, everyone has been aware of that for quite a long time here, but we are more than happy to keep Diafra. We like him and there is no problem if he is still here.
"I don't want any of them to go. We need to add to our squad. My intention is not to let anyone go.
"What I will say is we have four or five strikers and the competition is tough for all of them. But I'm happy with that. It would take an awful lot of money in this window to prise them out."
Moyes has so far been frustrated in his attempts to add to his squad, so much so that he suggested an overhaul of the transfer window.
"In Italy all the clubs go to the same hotel for one day, all the chief executives, the agents, they do the transfer business in the one day and it's done by midnight," he said. "Maybe it would be better if we had a day like that here in England, instead of transfer deadline day where everyone is wearing a yellow tie."
Moyes will be without Michail Antonio for Saturday's trip to Huddersfield but Marko Arnautovic returns after a tight hamstring.
