Chiellini admits they went into the game under pressure.
"We analysed everything over the past few days and saw that certain things could have gone differently," the centre-back said.
"But I can say that I saw the right spark in Madrid and today we once again saw another Juventus, ruthless and aggressive, just as the Coach wants.
"It was a true Juve performance. Now we'll be confident in approaching Wednesday's game against Catania."
