With Juventus back in Serie A for the 2007–08 season, Chiellini again was a starter for the club at left back, but following injuries to Jorge Andrade and Domenico Criscito, he was shifted to centre back again. Chiellini had a tremendous season and eventually made the position his own. Alongside fellow centre-half Nicola Legrottaglie, the duo were instrumental as Juventus finished the season with the joint second-best defensive record. The surprising aspect of this is that neither were considered remotely close to pinning down a centre back position in the summer before the season, with Domenico Criscito and Jorge Andrade preferred as the starting duo. He has been a regular fixture in the Juventus backline since their return to Serie A and was notably named Man of the Match in a game against Juventus rivals, Internazionale when he won a physical and heated duel with former teammate Zlatan Ibrahimović, keeping the Swedish striker at bay. Chiellini extended his original contract from until 2009 to 2011 on 12 October 2006. On 27 April 2008, Chiellini scored twice for Juventus in 5–2 win over Lazio that confirmed Juventus's place in the Serie A top four. on 26 June 2008, Chiellini extended his contract with Juventus until 2013.
