Both are the weak link at the back when playing. Since CB is more likely to cost a goal from a mistake, I'd shift our weak link in defense to the left side.
With Bonucci being suspended i think that we will finally see a Barzagli-Chiellini duo in the back. People are talking about Sorensen but i really think that despite this being a home game against Novara, Conte wont risk playing an inexperienced CB in this game. I hope he doesnt.
