Inter Milan chairman Massimo Moratti is left shocked by Mario Balotelli's behavior after the win over Barcelona, but still has faith in the controversial youngster. Balotelli, who came on as a second-half sub in the 3-1 Champions League victory, threw his shirt after the match before clashing with some of his teammates. It was reported that the 19-year-old has been attacked by veteran Marco Materazzi in the dugout and Moratti admitted that the shirt gesture caused unrest at San Siro. "It is difficult to patch things up now. It's not impossible, but he will have to pay for something," said the Inter chairman. "It's like he committed a public suicide. His gesture was too sensational. "But my desire is to continue with him, because he has talent and the character to become a great player - he only need to overcome certain obstacles. "I am not underestimating this problem, because if he acts like that, there is a problem. "But nothing is impossible. It depends on how some things are tackled. We will try to patch things up with the team, the coach and the club. I think it's possible." Meanwhile, La Gazzetta dello Sport reported that Balotelli is eager to leave the Italian champions at the end of the season.
