In an interview with AS on Friday, the former Chelsea boss admitted he has no immediate plans to accept such a role.
"We'll see although it will be later rather than sooner, much later," he said.
"I am 49 and will be 50 when this season finishes, but I still think I'm at the beginning of my career.
"A few years ago my wife said that some day I would stop, we would enjoy our children, our hobbies. But right now I'm a full-time coach.
"Even now, after all my experiences, I still feel the same excitement, the same joy I felt on the first day I won and I feel the same anger, the same disappointment on the first day I lost.
"So I say that for now, and for a long time to come, I'm not going to train a national team. That is not for me yet.
"I have to train 400 times a year and manage 60 or 70 games. I need to be with players, on the pitch and the dressing room every day. I like to train every day and see my players three times a week."
