Arsenal boss Arsene Wenger would not be drawn on whether he plans to make a move for a new striker in January, despite losing Nicklas Bendtner for "weeks" with an ankle injury.

The Denmark international opened the scoring late on in the Gunners' victory over Cardiff City on New Year's Day before Theo Walcott added a second.

But Bendtner, a second-half substitute for the recently recovered Lukas Podolski, picked up an injury while scoring the goal.

"Nicklas is a player who has gone through some difficult periods, so I want to give him credit tonight," Wenger told reporters.

"I told him already today, he’s back to his level where I want him to be, and if he continues to give a lot like that he will come back into the team.

"But unfortunately, he got injured today and it looks like it is not a question of days but weeks with a sprained ankle. And I’m very sad for us, but especially for him as well."

Arsenal faces an injury crisis up front following the injury to Bendtner, with Olivier Giroud picking up an ankle problem in the win against Newcastle on Sunday, while summer signing Yaya Sanogo has been sidelined for some time.
