Ribery retired from international football in August, after he was forced to miss the World Cup with a back injury.
He said: "With France - I'm finished. For two years I did everything to play at the World Cup - in qualifying I was the one with the most goals and most assists.
"France were in Brazil thanks to me. But all that is in the past. I'm really disappointed with what happened."
On the possibility of German citizenship, he said: "Why not? I can imagine staying in Munich after the end of my career.
"I have bought a very nice house, I feel good here and I like the mentality.
"My children are doing well at school, they have German friends.
"My son Saif was born here, he may even one day play for Germany.
"My eldest daughter Hiziya always makes fun of my German, and I laugh with her. I did not learn the language in school, but in my daily life, from other people."
