Balotelli had a spotkick saved - the first of his career - in the 2-1 defeat.
"I didn't speak to Mario, but I'm told he received another booking. He received a fair few kicks, including many from behind, though he overall had a good game," the Coach told Sky Sport Italia.
"When games are over it's better to stay quiet and I am against hysteria. It's best to just shut up and leave rather than stay there arguing with the referee, as it's not going to change anything. Balotelli needs to improve that."
