Brazil will look to put the disappointment that was the 2015 Copa America behind them and get back to the friendly business of football again when they play Costa Rica in an international friendly in New Jersey on Saturday.

However, you look at it, Brazil were disappointing in the Copa America, and what Dunga needs to do now is find the right balance in the team and personnel, who can help them in the soon-to-come World Cup qualifiers.

One player, who is, without doubt, crucial is Neymar, and Dunga is confident of being able to field the Barcelona superstar, even after the forward limped out of training on Thursday with an apparent knee problem.

"We will use Neymar," Dunga said. "He will be used. We brought him to have training, competitiveness, motivation.

"But when it comes to a competitive player, he wants to play. We'll have a moment we'll use him. How we use him is being weighed."

Another player desperate to make an impression in the national team squad is Douglas Costa, who has started life at his new club Bayern Munich in ridiculously-good form. If Neymar does not start the game against Costa Rica, Costa could be the one who gets the nod to play in his position.

"I was in Ukraine for five years but prepared to play at Bayern," Costa told O Globo. "Now I have to grab this opportunity. At Shakhtar [Donetsk], I played more on the right and when I arrived at Bayern everyone spoke of [Arjen] Robben, [Franck] Ribery but I did my job.

"Here it is no different. Of course Neymar is a great player, but I want my place."

Costa Rica are also a team dealing with change, after Paulo Wanchope resigned from his post after that ugly fight with a fan in the stands. Oscar Ramirez is the man who has been given the job of taking Costa Rica back to another World Cup, and the players have already been impressed by the new coach's aptitude.

"He cares for everything, even the smallest detail, because that leads to victory," Costa Rica defender Giancarlo Gonzalez was quoted as saying by Goal. "We have a settled game plan, which involves keeping possession of the ball.

"We will all give our all to make the adaptation easier, and ensure the results come."
