Giroud has only featured three times in the Premier League this season, starting only one of them - that was against Leicester City back in August.
The 33-year-old has been warming the substitutes bench this season since Frank Lampard's arrival after Tammy Abraham was chosen as the preferred option to lead the line for the Blues.
Yet to score also this season, it hasn't been the start that Olivier Giroud would have wanted, especially trying to impress a new manager.
But after speaking last week saying 'he will not accept it' in terms of lack of minutes at Chelsea, the forward has reinforced his beliefs and has said strongly that if he is left with no choice but to depart, he will.
Talking after he scored in France's 1-1 draw with Turkey on Monday night, Giroud said: "I'm going to fight for my place at Chelsea and we will take stock of the situation in January.
"If you ask me whether I want to leave I'll say 'not necessarily' – but other things enter the equation. I cannot be happy with what I have at the moment. I am 33 but I still have several good years left in me.
"I still have the legs and a profile that I think will enable me to keep playing at the top level. I feel in good shape physically and I lead a healthy lifestyle. I want to enjoy myself and play matches.
"That could be for Chelsea – who are my first choice – or elsewhere. But if they force me to make a decision I will do it – just like when I left Arsenal."
Chelsea face Newcastle United in their next fixture in the Premier League on Saturday afternoon at Stamford Bridge.
