Sacchi attacked Balotelli after his performance in Italy's draw with Poland.
“Intelligence isn't only necessary in football, but also in life," Mino Raiola told Adnkronos news agency.
“With his words, Sacchi clearly showed he has no intelligence or class. I don't understand why we are listening to someone who is living on past glories and taking the credit for leading a Milan side that was so strong it would've won without a Coach.
“Sacchi just has to thank (then Milan President Silvio) Berlusconi and think of the World Cup Final he lost with an Italy side that should've won that trophy.
“After Milan, he didn't win anywhere else and has no right to be giving lectures. After all, what he said about Mario confirms what people have said about Sacchi for a long time: he's finished. He's just pitiful now."
