Currently with Santos, Neymar could yet be tempted back to Europe by Fener and the chance to play for Mourinho, says Fanatik.
Boosting Mourinho's plans is a clause in Neymar's deal which clears him to leave for Europe without a transfer fee involved.
Fener are now exploring whether they can put together a package to convince the former Barcelona and PSG star about relocating to Istanbul.
Neymar said recently: "What are the chances of staying? From 0 to 10, 7. My story with Santos will never end, I was born in Santos and I want to die there. It's my home, it's my favorite team and I'm doing everything I can to help Santos.
"So far I've helped more off the pitch than on, but that wasn't the goal. I came to recover myself and find happiness, and I'm in this process, readjusting my body to get back to my best. I want to get back to my best. Today I'm very happy at Santos, Santos is my home."
