"It was important to win against a tricky team like Torino," Nocerino said. "I have tried to put into practice what I have been taught - sacrifice, commitment and a never-say-die attitude.
"I have tried to do that in the good times and the bad times.
"Berlusconi can return to politics, but we need him. He always gives the players confidence - he is a great motivator."
