The defender was part of the Juve team that lost 1-0 to Chievo Verona yesterday.
"We are absolutely embarrassing ourselves out there," blasted Chiellini. "We have many injuries, but that is not an alibi. There's no point hiding here. We are trying, everyone is giving their all in terms of effort, but the results are pitiful.
"We don't create chances and concede far too much. You can cling to bad luck, but obviously today we did nothing to win the match.
"We can't seem to get out of this spiral and I don't understand why. At the end of the game I was dispirited. That wasn't the case on Saturday.
"The problem is we do not create scoring opportunities, as in the last three Serie A games we've barely had a shot on target. We hope to find the light at the end of the tunnel."
