Yup, let's sell our best player in probably the most consistent part of our team from last season. Yeah, makes sense. He was also the second name on the team sheet, played the most number of minutes and probably the third best player on the team last season. We have tinkered enough by letting our best player go and building an all new attack. Now let's build an all new defense. Makes sense.
And no, we can't replace Bonbon with a fourth freebie CB and play Barzagli and Chiellini. Barza started all of 12 matches last term and got himself injured twice. At 34, he's no spring chicken.
