He explained that he is relaxed about the decision and is not putting pressure on himself to play for Germany again.
Leno, who will turn 34 in March, said that everything was respectful when he decided not to join the team, and that no doors were closed.
He played nine international matches for Germany, with his last appearance in 2021.
Leno clarified that he never said he was retiring and that he made the decision to concentrate on Fulham rather than traveling with the German national team and potentially sitting on the bench or in the stands.
