After beginning his career with Inter Milan in 2005, Bonucci spent the next few seasons on loan at Treviso and Pisa, before moving to Bari in 2009. His technique, ball-playing ability and defensive performances alongside fellow Italian centre-back Andrea Ranocchia earned him a move to Juventus the following season, where he later became a key member of the club's three-man defensive line, alongside Giorgio Chiellini and Andrea Barzagli, establishing himself as one of the best defenders in world football. Among other titles, he went on to win six consecutive Serie A titles with the team between 2012 and 2017, having also played two UEFA Champions League finals in 2015 and 2017. In 2017, he moved to AC Milan, and one season later returned to Juventus, winning two more consecutive league titles.
