After only one set of games in Group B at the South Africa World Cup 2010, chances are that we will know who progresses to the next round tonight.
If Argentina win, they are 100% of making it through. Even with one more game to play, they would have 6 points. For Greece or Nigeria it could at the same time be the match that will decide who goes home. If either team loses tonight, they are almost sure of their defeat. A loss would leave them with 0 points, and the other team taking the precious 3 points.
If however we have a draw in the Greece - Nigeria team, things are not so clear. Then it is everybody's game.
