Balotelli left Manchester City in January for Milan.
He told the Sunday Mirror: "It is a dream to play against Manchester City in Europe. I had a good time there - and had a lot of success there. I still have friends in Manchester and I would like to go back and say hello to the fans that were so good to me.
"It would be mixed emotions, going back - because I would be going there to win, but I hope Milan meet them in the knockout stages."
