The France striker believes the goals will eventually flow for him.
"It was a good pass from Alex (Oxlade-Chamberlain) and I think that I needed to go round the keeper as he came out quickly," Giroud told arsenal.com. "If I chipped the ball, the defender could have saved it. So I think I made the right call.
"I scored in midweek [against Coventry] and it was really good for me to score. And I will keep working hard to score goals."
