Arsenal boss Arsene Wenger was again cryptic about a new defensive signing after defeat to Liverpool.
Wenger saw Laurent Koscielny break down in the first-half yesterday.
He told arsenal.com: "We look, you know? But we try to do the right things for the Club.
"I think Koscielny and Vermaelen are a fantastic pair of centre backs but it's very difficult as well because if you buy another centre back and then someone gets injured I have to buy another one. You cannot do that every time you have an injured player."
