Aziz Yıldırım's response to Fatih Altaylı's allegations: If you have the courage, reveal your name

Fenerbahçe's former president Aziz Yıldırım responded to journalist Fatih Altaylı's claim regarding his company.
Altaylı claimed that Aziz Yıldırım's company DEARSAN had made an agreement with the Koç Group regarding the defense industry and that the Koç Group would now also have a share in the production of these ships.
Making a statement on his social media account, Aziz Yıldırım used the following expressions:
"Dear Fatih Altayli,
My company currently manufactures military ships and is working to manufacture them for countries all over the world. As Dearsan, we purchase "Underwater Phones" from Koç Defense, a subsidiary of Koç Group; we do not have any other cooperation apart from this. Please tell that friend of yours who lies that you mentioned in your article not to make such comments about things that he does not know or is not sure about; and not to mislead you. Do not reflect things that you are not sure about in your lines. If you have the courage, write your article by giving the name of that friend and let us have the chance to meet and talk to him.
I always express my views and thoughts about Mr. Ali Koç and the Fenerbahçe community when necessary.
Kind regards"
