Chiellini has had a tough start to the campaign and his performance against Genoa on Saturday was questioned by some in the media.
"He made mistakes and it's right to accept criticism," Claudio Chiellini told Tuttosport. "Giorgio is the first to be critical of himself.
"However, the media attacks seems a little excessive and it seems as if they are looking for a scapegoat," he continued.
"These are just episodes, all unfortunate ones as every time they happen Juventus concede a goal.
"But don't forget that he has given a lot to Juventus over the last six years."
