The striker was replaced at half-time of their closing 1-0 defeat to Uruguay and a yellow card picked up in that game meant he would have missed the last 16 fixture if Italy had won, but Galliani believes that he does not deserve to shoulder the blame.
"I don't like that it seems as though the national team lost due to Balotelli. Italy lost for other reasons," he said.
"Balotelli has been the only striker who scored, others didn't have a shot on target.
"It's not understood why people only talk about Balotelli, when the national team had a coach, technical staff and 22 other players.
"Let's talk about the group. Now it seems the disappointment has been Balotelli. I don't understand this and I prefer avoiding other comments."
