The Liverpool striker is the subject of a £40million bid from the Gunners with French attacker Giroud welcoming the proposed transfer.
"I think we need maybe two or three more players. Yes, that's what we need. To show ambition,” said Giroud who joined Arsenal from Montpellier last summer.
"The club has to show the fans that we want it. Me and my team mates, we need it as well. It's all about the team. It will be a really positive thing if we have a new striker.
"I am not worried but I will wait until September so we know the team, the players. I never used to read the newspapers and I don't want to change my way of life but I have heard a lot of things and I know we need a striker.
"The most important thing is the team. We are waiting for one but we don't know. I think it will be good for the team and for me as well to have another striker, to have more competition between us.
"But I think I could play with him or without him. So I will be able to be in the first XI this season. I really want to be in the first XI this season but we will see."
