Agree but his miss doesn't give Cagliari a goal. We'd conceded nothing in almost 7 games (6?7?) until that penalty. Dusan should have scored and Luiz should have not been an idiot, but I'm replying to people blaming Dusan for an incident which has zero to do with him.
People just like to bandwagon.
Edit: and now FC7's dive is his fault as well

What's next?
