Despite victory over FC Copenhagen, Juve must avoid defeat away to Galatasaray to reach the knockout phase.
"The result in Madrid does favour us, even if there is regret we aren't already qualified due to the points we dropped along the way," Chiellini told Sky Sport Italia.
"Copenhagen clammed up very well and allowed us very little compared to the meeting in Denmark, when it really did look like a siege.
"We did well to win the game and that is the most important thing."
