Wenger has been pleased with the summer signing from Montpellier, and insists he is only going to get better.
"He has good physical potential," he said. "He wants to play every single game, he has a good basic stamina and he can absorb the games.
"He can absorb the body to body [challenges] because he's a strong guy. I think you will see more from him next season, and there's a lot more to come from him.
"He is very extrovert but as well he has a basic positive nature. He wants to do well, he is desperate to do well, but he is not the one who hides afterwards.
"He stands up for what he has done and I feel he deals quite well with that."
