The defender wants to play more regularly, but he also recognises that it is a very strong squad and results are the priority.
"It is not a bad team, we have some strong players who, like me, want to play every game," the Frenchman told The Times.
"Sometimes you can be frustrated but you come to accept it. Sometimes it is not easy. What is more important is the club is winning.
"I am a competitor and, if I was not, I would just sit on the bench and get my money. In the past I showed that I do not play for money, I play because you know the football was my dream when I was young."
Gallas, 34, added: "I have maybe two or three years to play and so I don't want to regret anything when I finish."
