Wenger sent Bendtner, 24, on a season-long loan to Juventus on deadline day.
He said: â€śIt is not for nothing that I loaned him to Juventus. He is a talented player.
â€śThere he will grow and then return to my team.
â€śI am convinced that at a team like Juventus, in a very difficult league, especially for strikers, he can make the final leap in quality.
â€śDonâ€™t forget, he is a boy of 24, the right age to prove who he is.
â€śThe talent is not missing â€” otherwise I would not have bought him from Copenhagen when he was just 16.â€ť
Wenger added: â€śWe believe in him and that is why we only gave him to Juventus on loan.
â€śWe have not sold him, only loaned him, and next year we will bring him home.
â€śI think he can resolve his problems with us and prove himself.â€ť
