The 28-year-old also backed Les Bleus boss Laurent Blanc to remain in the hot seat after the Euros.
"I think the team is playing better and better," Ribery told RTL Radio.
"There is a good atmosphere within the group and we want to succeed in doing something in the Euros."
France is on a 17-match unbeaten run under Blanc, and Ribery backed the Frenchman to continue in his role regardless of what happens in the summer tournament.
"I hope he continues with Les Bleus because it would be important for him and the players of the French team," he said.
France is drawn in a tough group at the Euros that includes England, Sweden and co-host Ukraine.
