Depends on what type of deal if its a negotation they should swap him with someone who is not needed in team , but using caldara and rugani in the exchange seems very dumb because both are young and very promising defenders , if he will comeback it will be good for team because of the fact that his deep playmaking ability is better than chiellini's or caldara's or any of our cb's , and he will also be a useful guy in the attack [ volleys , headers etc ] and also he knows players better than our many cb's who are new to juve .
