The North London club have failed to find the net in the first two games of the season and Giroud's ambitious attempt during Arsenal's 0-0 draw with Stoke City yesterday was the closest Arsene Wenger's side got to scoring.
"I hoped [my shot] would go in," Giroud told the club's official website. "I saw the keeper off his line and I did not see Aaron [Ramsey] for a cross. So I tried to take my chance.
"[It means] we have to wait for our [first] victory. But it is coming soon. We played well and had some good situations in front of goal. We just have to score now - me too."
Arsenal go up against Liverpool at Anfield this Sunday.
