The Rossoneri have completed the â¬20m capture of the Italian international striker despite the frequent complications.
âIt wasnât easy to bring Mario back to Italy, we had to take it one step at a time,â Mino Raiola told Sky Sport Italia.
âThe 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.
âI thank Milan who always believed and who never pulled out even during the most complicated economic times.
âFortunately, weâve been able to bring back a top player to Italian football. Mario is a great talent and he still hasnât shown half of what he is capable of.
âBalotelliâs arrival increases the value of Serie A by 50 per cent and it lowers that of the Premier League by 50 per cent.â
Milanâs interest in the player was unclear at one stage after President Silvio Berlusconi described the former Inter man as a bad apple.
âIt was a misunderstanding,â Raiola added. âThe fact that Milan signed him is the most important thing. Words donât matter, facts do.â
