Well, Saudi Arabia are usually the whipping boys of WC. It's a shame there are the same four, five qualifiers from Asia over and over again. North Korea 2010 was an exception, they had a remarkable run in the qualification but turned out to be uncompetitive in the WC (that a team from an isolated country could qualify says a lot about the quality of Asian football). Some teams are making progress (like Vietnam, Thailand) but it's a long way to develop players who can compete in, let's say, an average European first division.
