The Danish international has slipped off of the radar at the Emirates Stadium of late, and was widely expected to leave the club over the summer.
However, moves to Crystal Palace and Hull collapsed as Wenger elected to keep him as back-up to Olivier Giroud.
Bendtner is set to feature in tonight’s Capital One Cup clash with West Brom, and has been backed by his manager to be a success over the course of the season.
“He has shown a good attitude in training and good, hard work. The real response that he can show is on Wednesday night,” Wenger told The Mirror.
“He had nearly gone somewhere else and in the end he stayed because it didn’t work out and we needed him here. Now he can convince everybody.
“We are open-minded, we believe in his qualities. I personally believe in his qualities.
“It’s just down to attitude and fighting spirit. When he has that, Nicklas can be an unstoppable striker. He gets his chance. Our job is about that. Take your chance.”
Bentner’s last appearance for Arsenal came in 2011, since when he has spent time on loan with Sunderland and Juventus.
He helped the Italians to claim a Serie A title, albeit enjoying a minimal amount of time on the field of play.
But, he could feature regularly for the Gunners this term, with Wenger having little in the way of striking options.
Can Nicklas Bendtner really be unstoppable?
