After the World Cup, Argentina hasn't stopped winning. They are currently on a streak of six consecutive victories without conceding a goal. This has also been the case in their two qualifying matches so far, where they won 3-0 as a guest against Bolivia and 1-0 at home against Ecuador. They have also been without conceding a goal as a home team for a long time.
Paraguay has not been performing well in recent years. They have won only one out of their last seven matches, with a 2-0 victory in a friendly against Nicaragua. Scoring goals continues to be a problem for the team. They have not scored in either of their two qualifying matches so far, losing 0-1 as a guest against Bolivia and drawing 0-0 at home against Peru.
Argentina is in great form and on a winning streak without conceding a goal. Paraguay struggles to score and has not been performing well recently, so everything points to another successful match with a clean sheet for Argentina.
