"When a coach really trusts me, I will give him everything I have," the Bayern Munich midfielder said on Thursday.
Ribery, who made his international comeback in March after a three-match ban for his part in the off-field drama in South Africa, said he had changed.
"My comeback in the France team was a very good thing for me. Even if I have not played my best games at that moment, the fact that I returned changed a lot of things," Ribery told sports daily L'Equipe in an interview.
"I know I owe them [Blanc and assistant coach Jean-Louis Gasset] a lot," said Ribery, who has been included in the squad to face the United States and Belgium in friendly games on Friday and Tuesday.
"We, [Patrice] Evra and myself, were almost banned from the French team."
"What the coach did [recalling him] is great. I want to give back on and off the field," Ribery said.
"I want to live with France what I'm experiencing with Bayern."
