The Frenchman has found himself restricted to substitute appearances and Europa League run outs this season.
But a hat trick against Dynamo Kiev reminded everyone at the club about his quality.
Now he wants more game time.
"No chance [I will deputise for another striker]," Giroud told reporters.
"I'm a competitor. I have been through a lot of tough moments in my career. I want to enjoy playing my football after winning the World Cup last summer.
"I want to take maximum pleasure on the pitch. That's why when I play I try to enjoy the game as much as I can. I want to play every single game and to be happy on the pitch. But I am not picking the team. The manager makes some choices.
"I play in the Europa League, and I am happy to help the team to go through the stages, step by step. The target is clearly to win it. The Premier League is another thing you know? I'm 32, but I'm still young. I feel very well physically."
"When I do the tests on the treadmill I have to say that I have one of the best tests [at the club]. Physically I feel very good. I have the motivation to carry on."
