Giovinco returned to Turin in the summer after two years at Parma and he doesn't fancy another transfer.
"When you go your separate ways, it is only normal for you to give your best," he told the Corriere dello Sport.
"I did that for Parma and I'm happy I did, but now I'm back in black and white and I want to stay here for a long time.
"There is no hurry to sign a renewal, but Juventus are the best you can get and it is my desire to stay here.
"I'll be 26 in January, where do you want me to go next?"
