The Gialloblu had trailed at half-time, but came from behind to claim a 3-2 win as they picked up their first points of the Serie A season.
"I wanted to underline how well the team fought back in a difficult moment," Cassano told Sky Sport Italia.
"There were people who were coming from Serie B or didn't play much recently, but they put in a great performance.
"In the locker room at half-time, despite being 1-0 down, the Coach told us to just play the way we know how. We listened to him and we won."
Parma host Roma in their next Serie A match on Wednesday evening.
