Speaking to reporters, Ter Stegen said: "It's not a pleasant situation. But the coach made the decision and I accept it, even if I don't agree with him."
Despite his frustration, Ter Stegen dispelled rumours about considering retirement from international duty.
"I told the national coach that one thing is the sporting aspect, the other is the human aspect," he said. "I want everyone to be able to rely on me. At the end of the day, you have a responsibility to the group. I will help wherever I can."
The 32-year-old was also quick to clarify that his relationship with Neuer remains professional and respectful.
"It has nothing to do with Manu, we have the same position," he said. "But on a personal level, it has nothing to do with him. I never wish anything to happen to him or for him to make a mistake. That's not me."
