I'm not sure there's much in it, personally, which is to be expected. South Korea have been a proper football nation for decades now and have earned the right to be considered as much. I'd have been surprised if they'd been shit.
As an aside, Danny Murphy's excellent knowledgeable co-commentary & punditry stands out in a sea of mediocrity. When you think of utter chumps like Hartson and McCoist. Two absolute gimps.
If the WC is a shop window, then we're a club likely to sell our players for top dollar if they end up excelling there. Equally though, there will be loads of players who have a shit tournament but are actually quite good. THOSE are the players we're likely to buy!
They are wonderfully unpredictable though.
I mean will they start kicking people or will they just bite opponents instead? I reckon they might return to old school gobbing in opponents faces for this edition though. I for one can't wait to find out.
