The 65-year-old's comments come after the Brazilian FA hit back at reports that they had asked Neymar to be rested for Saturday's crucial Primera Division title-decider
Diego Simeone's men travel to Camp Nou on Saturday knowing that a draw or win would guarantee them a shock title victory, while defeat in Catalunya would result in Barca taking home the trophy once again.
With Brazil's Dani Alves and Neymar involved for Barca, Scolari is hoping that his two players can be given a boost ahead of the World Cup this summer by winning the Spanish title.
"We not only want our players to play but to be champions," the coach told reporters. "That will boost our morale and self-esteem and, with that, the Brazilian team also wins."
Scolari's comments came after the Brazilian football association (CBF) denied that it had requested that the Catalans rest Neymar in Saturday's crucial game, as reports in Spain had claimed.
"The reports, which are wrong, are completely the opposite direction and thoughts of members," the CBF said in a statement.
Brazil feature in their first match of the World Cup - in which they are hosts - on June 12, with the final to be played on July 13.
