Fatih Terim, the manager of Turkey's national football team, resigned Wednesday, the Turkish Football Federation (TFF) said.
In a statement on its website, the federation cited "non-football related topics" as "wearing out" both Terim and the TFF.
Terim returned to coaching the national side, his third spell in charge, in 2013. However, he has failed to achieve the same success of his second tenure, when Turkey reached the semi-finals of Euro 2008.
"Recently, several non-football related topics that occupied media coverage has come to a state of wearing out Turkish Football Director Fatih Terim and the Turkish Football Federation," the statement said.
"Parting ways is the healthier way for both sides.
"We would like to thank our valuable manager for his services to Turkish football, who proved himself in Turkey and in the world with his success and wish him good luck for the rest of his life."
