Gunners boss Arsene Wenger has no doubt the 25-year-old, signed for a reported £13million deal, is perfect for the Emirates Stadium.
"I have known Olivier Giroud for some time," the Frenchman told Eurosport.
"The first time I saw him, I found he had something intelligent and dangerous. I always said he could score goals and assist his partners.
"Our game is based on cooperation between the players in the offensive phase and he will integrate easily.
"I don't like simple goalscorers, they must also add to the collective.
"He is good in the air which is rare. He is quite complete and has a great room for improvement."
