Now back with France this week, Giroud was asked by local reporters about his reasons for the transfer.
"It is certain that for me, the choice was clear, I had to leave Arsenal. It was like that," he began.
"From the moment when the transfer window opened, the coach had decided to take a new attacker, he paid a certain price. It was obvious that I had to leave. You're not on top when you play less and see your teammates on the field. I could not be satisfied with this role, even more with the signing of a new attacker."
