Chiellini says Roma's resurgence has surprised him.
"Roma surprised everyone, as I did not expect them to start with seven consecutive victories. They are also playing great football and at times remind me of the Juventus we saw two years ago, especially in their enthusiasm to overcome difficult situations.
"They have such energy that it allows them to do anything. It is exciting to watch them play. They can be stopped, just as all teams can be stopped, but I hope they are not too consistent like this.
"Considering the fixture list Juventus have had a good start and we must continue taking it one game at a time."
