He said: "Galatasaray want me to join them and Celtic want me too. If I could choose there is no doubt I'd prefer to join Celtic.
"They are a big club with an amazing football culture and there is nothing more exciting than the prospect of playing in a Glasgow derby against Rangers.
"I am talking about the situation to Milan and hoping a move can take place. My desire is to play outside of Italy next season.
"I've been here a very long time with Inter and AC Milan and I want to taste a new league."
