Giroud scored in the 3-1 victory and was asked if he was staying at the final whistle.
"I am still an Arsenal player for the moment. I want to prepare well for the season," he replied.
"It is always nice to score for the confidence. We were very efficient in the first-half and we could have scored more after the break."
On playing with Alexandre Lacazette, Giroud added: "He is a good player so it is always easy to play with this kind of player.
"We have a good understanding and had the opportunity to play a little bit in training with France. I think he will settle well to the Premier League. "
