Bonucci began the season by winning the 2012 Supercoppa Italiana with Juventus. He made his Champions League debut against Chelsea in the group stage and scored his first goal in the competition against Shaktar Donetsk in October 2012 in a 1–1 draw. In December 2012 Bonucci was criticized for diving in a league game against Palermo on which was described by a number of journalists as "the worst dive ever". He was booked by the referee during the game and subsequently given a one-match ban and a €2000 fine by the authorities. Juventus finished the season by winning the 2012–13 Serie A title.
