You guys are harsh on him. Main reason for that big gap being back there is our D always stay wide while in possession to provide options for pass, especially when the opposition applies pressure. I love Mirko, but that goal IMO still goes back to that silly, unfortunate give-away that caught everyone off guard, otherwise you have to question everyone's positioning from our mids to Bonucci that not only filled the offside, but didn't provide any cover either. Perhaps Martin's mistake was not fouling Sansone like some already said here.
