Arsenal boss Arsene Wenger admits he's yet to move in the winter transfer market.
Johan Djourou's suspension has compounded Wenger's concerns and he may seek a short-term option this month.

"[I am expecting a] quiet [market]. Europe is depressed and there is not a lot of money available, only some clubs who have exceptional resources. Let's say that clubs who are not linked with the economic environment at the moment can buy!"
