The 31-year-old is a member of Didier Deschamps’ World Cup squad ahead of the major tournament in Russia next month.
The veteran Premier League striker made the decision to move to Chelsea FC in a £21m deal from their bitter rivals Arsenal in the January transfer window.
Giroud was out of favour at the north London outfit in the opening months of the season after Alexandre Lacazette completed a £52m move from Lyon last summer.
Arsenal spent a club record £56m fee on Borussia Dortmund striker Pierre-Emerick Aubameyang to seal Giroud’s fate at the Emirates Stadium.
Giroud hit the ground running at Chelsea FC with a return of five goals in 18 appearances in all competitions.
The French striker impressed in Chelsea FC’s 1-0 win against Manchester United in the FA Cup final at Wembley earlier this month.
Giroud believes swapping Arsenal for Chelsea FC saved his spot in Deschamps’ travelling party for the 2018 World Cup in Russia.
“I had to impose myself at Chelsea all the same,” Giroud is quoted as saying by the Daily Star. “I´ve always been lucky enough to have made the right decisions, if I can say that.
“I’ve always felt that I’ve had good fortune in that way. It’s not just about making the right choice.
“You have to make your mark too. I had the chance to do that and I’m very happy. It’s a development in my career in terms of my club.
“I feel very good there and it was definitely a new challenge that was needed for my development, for the rest of my career, and also for the World Cup.
“I performed for Chelsea and that helped me keep my confidence up and to be in form so that I would be ready for France.”
Chelsea FC finished in fifth place in the Premier League table to miss out on a place in the Champions League next term.
