Argentina is in very good form now Ecuador team does not seem to be able to win against Argentina now. However, they may be able to score full points against Paraguay. And they can only be in the top 4 of the points table if they win a match. So Ecuador should now focus on their next match and try to win. If they can play well against GD Argentina then maybe they can share the points.
This is not true. They can lose both matches and still be in the Top4, and it's even quite a probable outcome. Check my post above.
Keep in mind that Ecuador has already 4 points more than the 5th and there are only 2 games left.
