Ozil came under fire from some supporters after being booed by a section of fans during the World Cup warm-up game with Cameroon.
Ozil has had an up and down last 12 months as he prepares for Germany's World Cup opener against Portugal next Monday.
The 25-year-old midfield schemer believes he has proved himself for club and country and feels he has taken on more responsibility since his move to Arsenal from Real Madrid last summer.
"I am no longer a talent but an experienced player who has played in three countries. I take responsibility," Ozil told Sport Bild.
"The FA Cup win means that I have won three finals. I was voted Germany player of the year three times running and in the team of the year in England - always by the fans - and that is also important to me.
"I feel that I have the trust of Joachim Low and Arsene Wenger and that I have earned it.
"I am now 25 years old and at that age every footballer in the world plays in a different way to what he did when he was 21.
"And, of course, my role at Arsenal is different in so much that I have more responsibility than I did at Real [Madrid]. And I like that."
