First versus second will kickoff tomorrow night.
"Over the past two and a half years we have shown that we are the strongest," Chiellini told Sport Mediaset. "We try to do it in every game, and we want to do it again on Sunday.
"Roma are having a great season - the fact that they are unbeaten shows that.
"They haven't lost yet, but we cannot wait to face them and see if they are at our level."
