Juventus defender Giorgio Chiellini insists everyone is to blame for their inconsistent form this season.
Juve are now five points behind Serie A leaders Napoli.
“With all due respect, when we don't concede goals I'm the first to say it's not thanks to me, or we defenders," Chiellini said.
“The defensive phase is about the team, otherwise it would be too easy, we'd be playing an individual sport, playing tennis with the defender against the striker.
“This is a team game, so it's about balance, the equilibrium is sometimes delicate and we all play for that.
“We definitely have to improve the defensive phase, and we're well aware of that.
“Bonucci? Leo is calm, it's difficult to change scenery and we're all cheering for him as a person, because the relationship between us is very good.
“He can return to the levels we're used to from him, but always behind us."
