Sacchi attacked Balotelli after his performance in Italy's draw with Poland.
“I think Sacchi is a great Coach and understands football well, but he was a little too harsh," said Mancini.
“A player knows when he has played well or badly. I think Mario knows full well what his performance against Poland was like. Criticism is part of the game.
“We are only at the beginning of this journey and will change several players from the Poland game, also to look after the lads.
“What we do need is a different attitude, bringing more players closer to the opposition penalty area. We are ready and know it can be a very important match. I won't say it's decisive, as there are another two to go, but we are facing the reigning European Champions."
