The Dutchman scored 30 goals for the Gunners in the Premier League last term but forced through a move to Manchester United in the summer by indicating that he would not entertain signing a contract extension.
Now the pressure is on Giroud and fellow summer arrival Lukas Podolski to hit the ground running in England but the Frenchman says that he is relishing the challenge.

"But I don't want to be fussy. I am happy. It works for me, because when you are a footballer you want to play. Inevitably, with Robin gone it will give me more playing time.
"People will expect a lot, and I really feel the desire to fulfil this expectation. It is better than if I was sitting on the bench."
Giroud rose to prominence last season, scoring 21 league goals as Montpellier defied the odds - and free-spending Paris Saint-Germain - to win the first Ligue 1 title in the club's history.
Arsenal face a similarly formidable task to overcome the Manchester clubs and Chelsea this term but the 25-year-old is not willing to rule out the current Gunners crop challenging for top honours.
"It's a good example for Arsenal," he added of his time at Montpellier. "We don't have the money of the Manchester clubs or Chelsea.
"Arsenal builds its team through training, through recruiting players who can become something. Arsenal has less money than some other clubs so we have to fight with other values.
"The collective, the group spirit, is good. We have an important role to play in this championship.
"Honestly, it will be complicated [to win the league], because the competition is fierce. But who knows?"
