The striker says he is desperate to enjoy a successful season at San Siro after agreeing to return on a loan deal from Liverpool
Speaking to reporters outside the La Madonnina clinic, he said: “I’m happy to be back.
“I’m fit, I just need to train with my team-mates. I don’t want want to talk too much, I’m only focused on working hard because I want to have a good season.”
The 25-year-old, who grew up in Brescia, dispelled suggestions that he felt like he was coming home, however.
“No, my home is in Brescia,” he said simply.
Balotelli, who scored just once in 16 Premier League appearances last season, has been frozen out of Brendan Rodgers’ plans at Liverpool.
The former Manchester City man scored 30 goals in 54 appearances during his first spell with Milan between 2012 and 2014.
