Because of health problems as a child and the difficulties his parent faced in Italy, Balotelli was placed in foster care with an Italian family from the age of 3.
Growing up, he experienced the frequent discrimination suffered by black people in Italian society. And since his professional debut in 2006, he has often been subjected to racism.
Aged 17, Balotelli was the most talented young player in Serie A. The more he scored, the more opposition supporters hated him. Yet such negative emotions were not only about football - they also showed a level of racism many Italians still struggle to acknowledge.
Many involved in Italian football have strongly defended Balotelli, including Italy's coach Cesare Prandelli and star midfielder Andrea Pirlo.
Many others, though, have shown a worrying level of racism. A journalist on TV called Balotelli "negro di merda" (shit negro). In 2012, leading national newspaper Gazzetta dello Sport published a cartoon representing him as King Kong. Last year, Paolo Berlusconi, the brother of the former prime minister Silvio and vice-president of Balotelli's team AC Milan, referred to Balotelli as "il negretto di famiglia" (the family's little negro).
In most instances, Balotelli has responded to such abuse with maturity and restraint.
Today, Balotelli is certainly the most famous living black Italian. In 2013, he was included in Time magazine's list of the 100 most influential people in the world.
Only the whimsical, at times absurd, events of international football competitions will tell if Balotelli really is the great champion the Italian team needs him to be.
His triumphs will be used as emblems of successful integration, and his failures will reassure racists about their most stupid and abhorrent beliefs.
But all that should really matter is that he is a great Italian football player.
