The former Tottenham star is on-loan in Turkey for the season and currently recovering from a thigh injury.
He said, "I can say that I'm in good shape mentally.
"Challenging situations create opportunities for people to learn. I also learned a lot from the events that put me in this difficult situation.
"I see this as an opportunity. I was really excited to take this opportunity. Coming here is a challenge for me. The Turkish league is a difficult league. I want to contribute as much as possible to my team here."
