The next few weeks will be key in determining whether Juve's season is a success.
Chiellini told TuttoJuve: "It was an important weekend, we managed to continue our consistency. Winning against the so-called smaller teams is hard, especially after a Champions League game in which we expended a lot.
"We did very well to continue to keep our order, to take advantage of our qualities and take home three key points.
"We know it is a crucial period. Between the League, Champions League and the first leg of the Coppa Italia semi-final, from now until 20 March when we have the international break, we have a very important period in our season.
"We are competing in all competitions and it would be a shame not to progress in each of them."
