Video - Cammarelle wins super-heavyweight gold
Roberto Cammarelle was in a league of his own as he stopped China's Zhang Zhilei in the fourth round to win the Olympic super-heavyweight title.
The Italian, who knocked out Britain's David Price in the semis, had quicker hands than his opponent and took an 11-3 lead into the third round.
That became 13-4 by the fourth before Cammarelle landed a vicious left hook which floored Zhang.
The Chinese boxer picked himself up but the referee declared the fight over.
Cammarelle said he no had no worries over the boxing judging that has caused controversy during the Games.
"I came here to win the gold medal and I've been fighting very well," he said.
"You saw it also in the semi-final. I could even have won with five Chinese judges."
