China has already made qualifying for the World Cup much more difficult for itself by failing to beat Singapore away. Goal difference is of paramount importance (after the number of points), so at home China need not just to win, but also to build up their goal difference.

I don't see anything particularly remarkable about China’s team. Singapore are of course at the bottom of the table, but the Chinese are in 3rd place, just above them. They played to a draw on Singapore’s field. Singapore can quite possibly cover the handicap, as well as avoid losing.
