The 22-year-old signed for the San Siro side in a deal worth around â‚¬21m from Manchester City.
â€śIt is a real honour to be here,â€ť he told a Press conference. â€śI have always wanted to play for Milan.
â€śI want to be an important player for this club. Being here really is a dream â€“ however, I'd rather let me football do the talking.
â€śI would have liked to have joined earlier, but I am here now.
â€śI also want to thank the City fans â€“ they always supported me, no matter what. I will always remember training with my teammates there, and the matches.
â€śThe rest though, I will not miss. The Premier League is a great League, but I am only thinking of this adventure.
â€śThe President has apologized for calling me a rotten apple,â€ť he added. â€śBut I did not hear anything anyway. I have never voted in any election, and I'm not ashamed of that.
â€śAnyway, it's a dream to play here. I've wanted this for a long time, and now I just want to play.â€ť
