When the two side's last met back in October at Rodney Parade, hopes were high in the Italian camp of a first victory in the Magners League but the Welsh side were clinical throughout, ending the game 36 v 5 winners.
Aironi are still without a win in the competition, but Phillips is hoping that will all change this weekend.
"The game in Newport was probably our lowest moment of the season, and I mean that as no disrespect to the Dragons," Phillips told the South Wales Argus.
"We didn't create anything or play any good rugby. It was just a huge disappointment.
"As a team we feel that we are a lot better than we showed that night so will want to prove that this weekend.
"The Dragons are a very physical and dangerous team. They are an honest group of players that work hard for each other, so it will be a tough game."
"A lot is being made about us having lost every game but that goes to show how hard the Magners League is and I honestly feel that we are making huge strides.
"This season has been a bit of an eye opener and the biggest thing has been the intensity of the league. Playing tough games week in, week out hardens players. We are not going to chase results because that is when you lose sight of trying to make improvements.
"However, we should have won our last two games - and that's not just a rallying cry, it's reality.
"We had our chances against Leinster and Cardiff Blues but those little things didn't go for us.
"Hopefully that will change but for me it is all about making little one per cent improvements, keep doing that and the win will come."
