Cisse is currently playing in Greece with Panathinaikos.
He told the Mirror: "It was a difficult start for me because the football is not as easy people think. I'm more confident now. The Panathinaikos supporters have been good and it's different, a completely different experience.
"But people know that I have a great affection for England and English football. I had so many great times there and my family are still there, so we will see what happens in the future."
