A return to the Santiago Bernabeu would see the 28-year-old team up with his hero Zinedine Zidane.
"Zidane used to be my idol. I always watched him play when I was a kid and I wanted to be like him," Ozil added.
"We play in the same position and he was a point of reference growing up. I was very nervous when I first met him.
"I think he is a great coach. He won the Champions League in his first season, it does not get any bigger than that. I am happy for him because he is a great person and I always believed in him as a coach."
