The striker netted twice as the world champions completed their preparations for Euro 2020 with a comfortable friendly win against Bulgaria and revealed that he has been given a complimentary moniker by his international colleagues.
Giroud said: "It made some of my friends laugh, because they call me that, the phoenix from Grenoble.
"It is a compliment because it means that no matter the circumstances, I don’t give up. When I am called upon, the most important thing is to get the job done.
"I had a couple of good passes from my colleagues. They know where I make my movements towards and I just needed to finish well.
"When we did not have the ball, we were good with our defensive positioning. It is when we do not have the ball that we need to make the effort and remain united. Tonight, that’s what we did."
There was some concern for France as Giroud's fellow striker Karim Benzema picked up an injury but coach Didier Deschamps didn't think it was serious.
The Les Bleus boss said: "He took a good hit on the muscle above the knee. He stopped playing because he felt it hardening but the medical staff are at his side.
"We have a high-level medical staff, we are going to do the right thing. It will get better day by day. I have no particular concern this evening. There is nothing dramatic."
