West Ham boss David Moyes would prefer if players did not leave the London Stadium this January.
He said: "The form of Marko Arnautovic and Antonio at the start has made it difficult for Chicharito and he was injured when I first arrived.
"He is a really good player, he thrives on things in and around the box but sometimes we haven't had the service to him."
Discussing outgoings from the London stadium during this window, the Scot said: "I don't want any players to go. Ideally we strengthen; my intention is not to let anyone go.
"We have four or five strikers and there is competition. It would take an awful lot of money to prise them away."
