Olivier Giroud is "convinced" he can still play a part for Chelsea but admitted he will reconsider his future in January if opportunities continue to be limited.
The striker has struggled to hold down a regular starting spot in two and a half years at Stamford Bridge since joining from Arsenal and has repeatedly been linked with an exit.
He fought off competition from Tammy Abraham to become first choice towards the end of last season but has fallen back down the pecking order under head coach Frank Lampard since the arrival of Timo Werner.
After being used for just 17 minutes in Chelsea's first four Premier League games this term, Giroud is determined to prove his worth and win back his place in the side.
"I've written a book called 'Always Believe It' so I'm not going to go anywhere without a fight," he said at a news conference while on international duty with France.
"There is competition but I will fight and we saw the rewards of that at the end of last season. I am convinced I have a role to play at Chelsea. We will see in January."
Giroud is one cap short of a milestone 100 for France ahead of their friendly with Ukraine on Wednesday.
The 2018 World Cup winner did not earn the first of those caps until the age of 25 and is proud of what he has achieved on the international stage.
"I signed in Ligue 1 at 25 - it's an atypical course," he said. "The chance to play for Les Bleus at that age was just a bonus.
"I never set any limits for myself and maybe at 75-80 [caps], I thought 'why not 100?'. It's a good number but I still have many years ahead of me."
He added: "If someone told me I was going to reach a centenary at 34, I wouldn't have believed it when I was at Grenoble or Tours.
"But, that's the beauty of football. I have always worked my way up through the ranks one after the other, thanks to great people.
"I am a good example for young people who do not turn professional at 17."
