I mean more the case of points, as match conditions dictate that you can't realistically take a goal off and say this would have been the result.
It's also that it's just down to luck as to whether mistakes actually result in goals.
Chiellini went through his poor patch at the start of the season and was unfotunate enough to give away a goal with every other mistake. Chiellini wouldn't have drawn the same criticism if teams had missed those chances, but whether those chances were taken had nothing to do with Chiellini.
Bonucci still isn't reliable, but he is improving - particularly in his decision making. He's not diving into challenges and taking himself out of the game as often as he used to.
However, his concentration still isn't good and he is still sluggish on the turn, which can makeit quite easy for a sharp forward to beat him.
