Atalanta had two players sent off on the day.
Prandelli said, "We wanted the win, and I think I can say we deserved it," said Prandelli, in an interview with Radio Rai. "We played against a strong team that has been working together for years.
"It was an exhausting game in which we had to give a lot, but we did a good job in countering them. The lads did really well.
"I sincerely hope we can build on this victory, because this group has the potential to do that."
