The Istanbul club announced on Wednesday that it was interested in bringing the Dutchman to Turkey, and talks have been progressing well, according to the official.
"Overall, I can say the talks have been positive, but he hasn't decided yet. He has family issues to discuss." Tulun told Milliyet. "Sneijder will notify us of his decision within 24 hours. I think it's going well, but I cannot say anything definitively. Sometimes, transfers that are 99 percent finished don't happen. For that reason, I am saying nothing.
"Things are moving well, but I don't know what to expect. We will announce the decision within 24 hours."
Sneijder has not featured for the Nerazzurri since September since getting into a stand-off with the club over signing a contract extension.
