Arsenal manager Arsene Wenger admits he is looking to bring in reinforcements in January but does not know if the cash will be available.
The Gunners scraped a 1-0 win against Portsmouth on Sunday to keep their faint title hopes alive.
"I want a creative midfielder," he told Canal+. "That is to say a second midfielder, because my team is right in terms of manpower and experience."
He continued: "I can't spend money I don't have. The [global financial] crisis is upon us and we feel it at the club."
One player Arsenal have been linked with is Zenit St Petersburg playmaker Andrei Arshavin.
However, Wenger refused to confirm he is chasing the Russia forward.
"There's no point in giving me names," he added.
