Italian scrum can take a bow, they caused some serious trouble.
Just rewatched the first Italian try. If you pause at the right moment, you get a good view of the England set-up around the posts. There's no one stood by the right post (from England's perspective) and a good 10m or so between Launchbury and whoever was by the left. The ball lands pretty much smack in that gap and while it looks like the English guys are reacting slowly (and probably are a bit), the Italian's run right into the right place and there was simply never going to be anyone near enough. Poor set-up.
