With both teams already eliminated from the race, it's essentially a dead rubber.
The Golden Star Warriors are rock bottom in Group B with just one win and three points in the bag from eight games.
That victory, ironically, came in just their last game - a stunning 3-1 defeat of China to end their miserable run and get some points on the board at last.
Oman have fared relatively better with two wins and eight points, but alas, it wasn't enough, and they sit in fourth place of the standings.
Yet, the Reds put up a spirited performance against heavyweights Australia in their last outing, fighting back twice in the match to secure a 2-2 draw.
