What was the most regrettable moment in Chinese football?
Was it failing to score a single goal and exiting in disappointment at the 2002 World Cup?
Was it the humiliation of having Japan steal the championship with a handball in the 2004 Asian Cup final, played on China's home ground?
Or was it the supremely talented national youth team at the 2005 World Youth Championship, which carried the hopes of countless people, only to fall apart and fade into obscurity after losing 2:3 to Germany and causing Krautzun to be dismissed?
If time could flow backward and the national youth team had defeated Germany, how would history have changed?
