Wenger is considering the possibility of a potential two-month loan deal for New York Red Bulls striker Thierry Henry.
"I have to think about that," Wenger said. "Short term is ideal for us, but I haven't made any enquiry yet. Thierry is not here at the moment. It has never come up in conversation.
"January 1 is the vital date for us. We have seven days to make decisions and I will make a decision in the next seven days on players."
