Wenger admits that injuries to key players have left Arsenal in need of another striker.
"Robin Van Persie and Bendtner contributed to many of the 51 goals we scored," Wenger told arsenal.com. "They were both in outstanding form and we miss them.
"But on the other hand we have played 19 games and if you multiply 51 by two it is over 100 goals for the season.
"That is absolutely tremendous and people don't realise how efficient we are going forward.
"I can understand that people are scared because we are short [up front].
"I don't deny that, but I always hoped for a long time that Bendtner would be available at the beginning of January but that is not the case now. So we have to look somewhere."
