Exactly that. As I said some days ago . . for all the hustle and bussle of the 'unfancied teams', if you'd missed the first 10 days of the W.C. and looked at the knock out round fixtures you'd be all 'meh, how obvious, at least the real World Cup can start now'.
I don't expect South Korea are going to change that.
This is probably the raggiest WC group stage ever for the 'big boys'.
