Derby d'Italia
Balotelli's disciplinary problems and his difficult relationship with Mourinho continued in the 2009–10 season. In November 2009, Inter drew 1–1 against Roma, after which Mourinho criticized his players, going as far as saying Balotelli "came close to a zero rating". Balotelli had another negative encounter with Juventus fans in the heated "Derby d'Italia" encounter in an away match against Juventus on 5 December 2009, which Inter lost 2–1. When he was elbowed by Juventus midfielder Felipe Melo in the shoulder, Balotelli fell theatrically onto the pitch, for which he was booked, while Melo was sent off for a second yellow card. The incident sparked an altercation between Balotelli's teammate Thiago Motta and Juventus goalkeeper Gianluigi Buffon. The tension between Balotelli and Mourinho reached its peak on the eve of the UEFA Champions League second leg against Chelsea after the young striker was not called-up, following an altercation with his manager. Despite Inter's 1–0 win at Stamford Bridge, Balotelli was criticized by several senior players, including captain Javier Zanetti and veteran defender Marco Materazzi, as well as by his own agent. In March 2010, he came under heavy criticism from fans after he publicly sported an AC Milan shirt on the Italian show "Striscia la Notizia".
