Boban spent 11 years at the San Siro between 1991 and 2002, and the midfielder was a key part of a remarkably successful side.
But as Milan struggle this season he has chosen to direct his ire at the 23-year-old, who has reportedly not been turning up to training on time, as per Sky Sports News, and is in poor form.
In quotes translated by Football Italia from an interview on Sky Sport Italia, Boban said:
Let’s stop always talking about this Balotelli. In his life all he has done is sit on the bench at other clubs.
He will always be smaller than Milan and Milan will always be bigger than him.
In my Milan side he would have carried bags for players such as Marco Van Basten, George Weah and Andriy Shevchenko.
Balotelli made a stunning start to his AC Milan career when he joined from Manchester City in the January transfer window earlier this year. He scored 12 Serie A goals in his 13 appearances, propelling the Rossoneri into the Champions League places (all stats via Soccerway).
But this season his form has been poorer. He has three goals from eight appearances in the league, and was sent off in a home defeat to Napoli.
The team are in the uncharted territory of 13th place in Serie A, with just 14 points from 13 games and a negative goal difference.
Balotelli tweeted cryptically at the weekend:
This is the end. :-)— Mario Balotelli (@FinallyMario) November 24, 2013
Boban says Balotelli's attitude would not have been accepted by club legends of the past, and called for him to take a leaf out of teammate Kaka's book:
He would have been slapped by people like Paolo Maldini, Marcel Desailly, Sebastiano Rossi, Alessandro Costacurta and Franco Baresi for not arriving on time.
His listless attitude demonstrates that he is unable to comprehend certain things with his brain; he doesn't understand what wearing that shirt means.
He should learn from Kaka, a boy who has won the Champions League, a World Cup, a Golden Ball. He’s certainly richer than Balotelli, yet he runs and works like a kid.
