The Gunners are preparing to meet PSG in the Champions League.
Giroud, speaking Telefoot, remarked: "This is a different competition.
"PSG acts as leader, favourites in this group. They will be ready, and we must make them doubt. I hope to score in the Park, I have already registered some goals.
"(Zlatan) Ibrahimovic? He had a very good season last year, he was very important to them. Somebody takes over. I fear Cavani. If there is a big night he can hurt us."
