Balotelli passed a Milan medical yesterday.
"As soon as I got the chance, I ran to Milan," he told Milan Channel.
"I had wanted to play here for a long time, but was at other clubs, so I didn't have the opportunity. Papers talked, but I knew I'd play for Milan eventually. The start of this season was negative, but with this jersey I will do better.
"I made some important choices, so I hope they can make Milan great and make me great too. I just want the fans to love me and for me to repay that love..."
