Under manager Antonio Conte, Chiellini returned to his original position at left back due to Barzagli and Bonucci's good run of form. After struggling to re-adapt back to his former position, he grew into his role and managed to keep Paolo De Ceglie, the only other natural left back in the squad, on the bench for much of the first half of the 2011–12 season. In the second half of the 2011–12 season, Conte switched to a three-man defence, where Chiellini partnered Bonucci and Barzagli in a very successful defensive system for Juve, who ended the season as Serie A champions, with the best defensive record, as well as being unbeaten in the league. Due to their performances together, the three-man defence earned the nickname "BBC", a reference to the players' initials, and soon the trio established themselves as one of the best defences in world football during the following seasons. Juventus lost the 2012 Coppa Italia Final against Napoli, but would later defeat them in the 2012 Supercoppa Italiana, although Chiellini would miss the match.
