2 matches remaining for CONMEBOL zone i think Ecuador chance is very wide open to finish at top 4 because next match against Paraguay they possibly will win and for the last match indeed met strong team Argentina but considering this team is already qualified i think Argentina will play with their reserve players and draw results is enough for Ecuador in this match if they win against Paraguay however if they successfull to qualified then this could be 4th participation in world cup for Ecuador
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.
