"Aironi are a heavy, physical team and they don't give up," said Edwards.
"They put in a good performance against Leinster last week and it took Leinster 70 minutes to break them down and that was away from home
"They are going into the game quite confident and I know we will have to work hard to get a victory out there.
"They have certainly improved since we last played them and I would say they are the most improved team this year.
"They gave away a lot of penalties away at the start of the season, but they have changed that and it is only a matter of time until they get their first victory and I just hope it's not against us this weekend."
The Dragons are on a three game winning streak and following their 30 v 22 victory over Edinburgh at Rodney Parade on Saturday confidence is high before the trip to Italy.
"We have brought a lot of balance to our game recently, we scored five tries last week, some though the forwards, some through strike play and some through support play and that is a really nice balance," he added.
"With Martyn (Roberts) back at full-back we have got a good balance in our back three with some strong strike runners.
"My target is simply to get more Magners League points than we did last year, the important thing at the region is to progress and we are in a good place to do that.
"Last year we stepped up towards the end of the season and we have to do that again this year."
