Nothing surprising about Chiellini's performance. He's really tough and he gives silly fouls quite a lot. Low intelligence football wise.
That's nothing new.
But he's a real beast more often than not and despite his occasional brainfarts, he's of great use. The problem is that there isn't a calm head next to him in defense, a more experienced player. As much as we love him, we can not allow Chiellini to lead the defense. He's a guy who needs to do the dirty job.
