Mesut Ozil believes that he has "earned" the trust of Arsenal manager Arsene Wenger and Germany coach Joachim Low.
The midfielder was booed by a section of Germany fans during the side's recent draw with Cameroon, while Die Mannschaft legend Lothar Matthaus this week also questioned Ozil's place in the team.
However, the 25-year-old has now hit back, telling German publication Sport Bild: "I am no longer a talent but an experienced player who has played in three countries. I take responsibility.
"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."
Germany get their World Cup campaign underway when they take on Portugal on Monday.
