The 32-year-old Frenchman is expected to be part of a summer clear-out at Juventus after a disastrous season.
Speaking while on tour, Trezeguet said: “I need to play with continuity and that hasn't happened in the last two years.
“It's not always because of injuries or knocks. I need to show that Trezeguet is still an integral player and in a position to influence a game and a result.
“I am convinced that I can do it. I have no doubt, but if I don't play then the doubts come from the others who don't see me and think that by now I'm at the end of my career.
“Even if I have a year left on my contract it doesn't mean that I am leaving. It doesn't just depend on me, but the club also.
“The coaching staff must make their decisions. They have only just arrived. Let's give them time.”
