One thing with home tournaments - home World Cups in particular - that people often forget is that it's the kind of thing everyone circles in the calendar for years. It's basically a life goal that many other things take a backseat to. Getting everyone to pull in the same direction, to ignore distractions, to not let trivial aspects get in the way, is pretty much the hardest thing in a tournament. So many of those tournament failure stories ultimately go back to issues in the player/coach/management dynamics..and it's much easier to avoid this problem when you're the host nation and you know this is a once-a-career chance to make an impact.
