Argentina coach Jose Pekerman is looking for improvement from his team when they take on Serbia and Montenegro.
Argentina earned a 2-1 win over Ivory Coast in their opening match, a victory that boosted the squad.
“To get a victory in the first game should give us confidence – we need to keep getting better,” said Pekerman.
“There were a few negatives in our performance and we will be working on that aspect of our game.”
Defender Roberto Ayala knows that Serbia and Montenegro will present a new set of problems.
He said: “I don’t know how Serbia is going to play, but it’s a team that played below its ability in the first game.
“I know the team can play better. Having lost the first game, they are sure to be up for this one.”
Striker Hernan Crespo, who scored in the opener, is not getting carried away just yet.
“You do feel that pressure when you go out on that pitch and it is never easy to start the World Cup with a win because everyone is anxious to do well.
“But we just need to take one step at a time and look to make progress.”
