Erdogan was recently in the United Kingdom, where he interacted with German born football players of Turkish origin, Ozil and Gundogan.
Ozil plays for UK's Premier League club Arsenal and Gundogan for Manchester City.
The two midfielders met Erdogan in London on Sunday, when the Turkish president was in the country for a state visit.
Erdogan, who is up for re-election next month, met Ozil and Gundogan, as well as Turkish worldwide Cenk Tosun, in London where he is on an official state visit during which he will be received by The Queen and meet Prime Minster Theresa May.
However, the DFB was far from impressed with their decision to pose for pictures with Erdogan, whose presidency has repeatedly come under scrutiny for alleged violations of human rights.More news: California reaches all-time high in sexually transmitted diseases
The two soccer stars also presented the Turkish President their signed jerseys.
The photos unleashed a storm of criticism from lawmakers across Germany's political spectrum and the DFB football federation, all of whom argued that Erdogan does not sufficiently respect German values. That's why it's not good that our global players let themselves be manipulated for his electoral campaign.
In a statement on the Turkish Football Federation's website, Demiroren added: "It is a very well known fact that our president... as a former player, is a big football fan who has massively contributed to the progress of the game in Turkey".
German national team's coordinator Oliver Bierhoff said that he would talk with the players over the issue.
"I still have absolutely no doubts about Mesut and Ilkay's commitment to playing for the Germany national team and how much they identify with our values", he explained. However, he said: "They were unaware of the symbolism of these pictures, but we can not endorse it, and we will discuss the matter with the players". "When you play for Germany you represent German values", Loew said at a news conference to name his provisional squad for the World Cup in Russian Federation.
