Arsenal eventually lost 0-1 in the match.

"When he is playing with a simple, he is the best. He was tall, big, and when you try to give him bait, he was able to master and retain the ball. No defender could pass him," Koscielny said on Arsenal Player. 

"He was really great and one of the best strikers. When he plays like this, with one or two touches and continues to exist in the penalty box, we could have scored a goal through air ball. I think Olivier Giroud had a work ethic that is very high. He not just a striker, he was able to score from any situation. "
