Three years after Cannavaro left Juventus, and following the end of his contract with Real Madrid, in the summer of 2009 he decided to return to the club. Cannavaro started the new season very well, forming good defensive partnerships with Nicola Legrottaglie, Martín Cáceres, Zdeněk Grygera, Fabio Grosso and most notably Giorgio Chiellini, in front of goalkeeper Gianluigi Buffon. However, from Autumn onwards, Juventus' form took a turn for the worse. Having been injured for a while in late 2009, Cannavaro struggled with his own form both on his comeback and subsequently, and Juventus were knocked out of the Champions League, finishing third in their group.
