Arsenal boss Arsene Wenger admits he could be busy in the January market.

Wenger says a new defender and striker is on the agenda.

"We hope to have Wilshere and Diaby back so in midfield we have the numbers required. But at the moment we are short at the back and if Gervinho and Chamakh go to the Africa Cup of Nations we are short up front more than midfield," Wenger said.
