While Wenger has been pleased with Gervinho's progress, he feels there is much more to come from him.
"The things he can improve are of course the quality of his finishing, but that is linked with confidence," he told arsenal.com.
"I believe he has improved his finishing because he worked on it in training, but for a while it was a more a consequence of lack of confidence than lack of quality.
"He rushed some chances, which means you want to get quickly rid of it rather than taking it in a confident way. Since he has found his confidence you see his finishing is clinical as well."
