“I felt a certain tiredness in my body and also in my head, which got me thinking. And the games at club and national level are not going to get any less,” he said.

“I will definitely continue to be a fan of this national team and very much hope that the upward trend can continue together – and then there is nothing to stop us from being one of the main title contenders at the 2026 World Cup.

“We have a fantastic coach, a really strong team and a great team spirit.”

Gundogan made his debut for Germany against Belgium in October 2011 but missed their 2014 World Cup triumph with a back injury. He was also ruled out of Euro 2016 due to a dislocated kneecap.

He became the first German footballer of Turkish descent to captain the national team and appeared at four major tournaments. He was also an unused squad member at Euro 2012.

“Ilkay was an outstanding captain, with whom I would have liked to continue working,” said Germany coach Julian Nagelsmann.

“The door to the national team is never completely closed, but we respect his decision and wish him all the best for his future, both professionally and privately.”
