Conte angered Bologna officials with his behaviour.
But Sannino said: "I don't like hypocrisy, I like real people. Any Coach would celebrate a positive result. Football must return to what it was, where people felt free to celebrate and raise their arms to the sky.
"I will not accept those who try to moralise and say his gesture was exaggerated. I also don't like players refusing to celebrate a goal against their former club. It's not a lack of respect, as football is a game, it is joy and it is celebration."
