The French striker scored a brace in the 2-0 win over West Brom on Monday night taking his season tally to four goals in the league.
Following the game, Wenger said: "Yes, he has found confidence and I believe he is adapting quickly to the demands of the Premier League.
"I think it's quite positive. Now he has to score away from home, but he was unlucky as well away to Stoke I must say. Overall it's a good sign that he keeps scoring at home."
