“We'll die once instead of dying every day. If necessary, we'll play [in the First Division] for a year and win promotion again.
"If you treat us like a pariah club in this country, and I say this to the state, to the TFF [Turkish Football Federation], to the media, we have to decide our own future.
"This is not some kind of blackmail or threat,” he added.
