The Rossoneri have completed the â‚¬20m capture of the Italian international striker despite the frequent complications.
â€śIt wasnâ€™t easy to bring Mario back to Italy, we had to take it one step at a time,â€ť Mino Raiola told Sky Sport Italia.
â€śThe talks broke down seven or eight times in the last 60 days. All the speculation in the media was annoying City, especially when it came to the payment methods.
â€śI thank Milan who always believed and who never pulled out even during the most complicated economic times.
â€śFortunately, weâ€™ve been able to bring back a top player to Italian football. Mario is a great talent and he still hasnâ€™t shown half of what he is capable of.
â€śBalotelliâ€™s arrival increases the value of Serie A by 50 per cent and it lowers that of the Premier League by 50 per cent.â€ť
Milanâ€™s interest in the player was unclear at one stage after President Silvio Berlusconi described the former Inter man as a bad apple.
â€śIt was a misunderstanding,â€ť Raiola added. â€śThe fact that Milan signed him is the most important thing. Words donâ€™t matter, facts do.â€ť
