Manchester City boss Roberto Mancini has weighed into the row involving Inter Milan striker Mario Balotelli.
Balotelli angered fans at the end of Inter's victory over Barcelona by throwing his shirt to the ground. He then allegedly clashed with teammate Marco Materazzi and later was jumped by Inter fans inside the San Siro carpark.
"I only read in the newspapers what happened and did not see it directly, but it's a shame for Mario," said former Inter coach Mancini.
"He is a good lad and a great talent, but certain behaviour ought to be avoided."
