Arsenal striker Olivier Giroud is delighted with his six goals so far in preseason.

Giroud is entering his second campaign as an Arsenal player and he says he has worked on the mental aspects of his game to improve his efficiency on the pitch.

"Confidence makes all the difference," he told Arsenal Player. "Confidence is the first thing you have to work on - you have to work on your mental [side of the game] and keep going. It is something you must have when you are a football player.

"I am happy with my efficiency. I had as well a good ball from Tomas, I had a good position to receive the ball and I finished well. I am happy with it and I want to keep going and help the team to win. Tonight we succeeded, we were efficient, Theo scored and Ryo at home as well so we are really happy."
