The World Cup winner has started just one Premier League game so far, with Tammy Abraham leading the line and scoring four goals this season.
The 32-year-old Frenchman stated last season that he wanted more playing time before agreeing a new deal, but that hasn’t been the case as yet.
Giroud is still keen to make his mark at Stamford Bridge.
Giroud was asked by Le Figaro whether Chelsea youngster Abraham will be able to keep him out of the team.
He said: “Obviously not! I have goals in my head.
“I’m here to help the new generation, but beware, the retirement time has not come.
“I’m still hungry and have a lot of ambition. I don’t want to be Chelsea’s No. 2 striker, for sure.
“Just because I’m here as an older brother for young people, it doesn’t mean I’m out on the sidelines.”
