La Gazzetta dello Sport has the scoop on the behind the scenes feverish negotiations between City, Mino Raiola, and Adriano Galliano for the biggest transfer news in this January period. I am not sure if Raiola would be too pleased in being described as a "cad." The long and short of it is Balotelli is joining his first love with City paid out €20m + €3m in bonuses despite Slivio Berlusconi referring to him as a "rotten apple". A statement he walked back somewhat.
Balotelli joined City from Inter at a price tag of €28m on August 10, 2010. City were demanding €37m which given his recent performances and his on/ off pitch conflagrations was outlandish. In 20 appearances for City (Premiership/ League Cup/ FA/ CL) this season he's managed just 3 goals. A steep drop off from his first season. Hopefully being back to the Serie, in the club he loves, and under the tutelage of Massimiliano Allegri who has a track record of nurturing troubled talent, he can flourish. It's risky but AC Milan seem to believe in him given all the financial troubles they find themselves in.
