It is a young and talented squad that needs experienced players like me, says the 38-year-old Frenchman according to the club's website.
Giroud left Montpellier in 2012 to represent Arsenal for six years. This was followed by three-year stays at Chelsea and Milan before he last year signed with Los Angeles FC, where he only scored five goals in 37 competitive matches.
After 57 goals in 137 international matches, he retired from the national team last year, as the top scorer of all time in "Les bleus".
Giroud was part of the World Championship winning team in 2018 and has also won the Champions League, with Chelsea.
