Wenger is delighted with the progress of Gibbs this season.
"They have done really well. That's another difficult decision I have to make in every single game. I would say for Gibbs it's the same as it is for Chamberlain because he has improved tremendously this season. I think October, November, was really a springboard for him where he moved forward. He's a candidate for higher up [now]," he told arsenal.com.
