The Viola won 3-2 - their first away win in five games.
"We were coming off an away match (against Empoli) where we thought we'd won and instead ended up with zero points, creating this enormous disappointment," Italiano said.
“Today we dealt with the situation differently when 3-1 up. We could've avoided the situation for their second goal, but the fact remains we allowed very few chances.
“I am happy for the lads, I heard people talk of us having some sort of taboo on our travels, but we proved that wrong too. Now we must prepare for the next match and see if we can make that step up in quality."
He added: “The leading pack have something extra and are going at a remarkable place, but we are closest to them and want to maintain this position. There are three games left to complete the first half of the season, then we'll see where we are."
