Brazil coach Luiz Felipe Scolari believes that Ronaldinho and Neymar rank among the world's best.
The 64-year-old has named both in his first squad to face England in a friendly at Wembley next month and the World Cup-winning coach has revealed he has high expectations of the two stars.
"I want what everyone else wants, which is that they play the football they are capable of playing," Scolari told reporters.
"Few can play the game better than them. I also want good behaviour. I want them to be responsible, regardless of their age."
The former Chelsea boss also revealed he is confident Brazil can claim their sixth World Cup on home soil in 2014, amid high expectations of his side from the public.
"We have placed our bets on a World Cup win and that is what we are working towards," he said. "The supporters are right to demand it."
Finally, Scolari refused to rule out a switch to a different system which would see them play without a proper striker, as Spain did at Euro 2012.
"I always like to have a stronger type of player in the penalty area," he said. "But that doesn't mean to say we can't change in the future and not have a fixed striker."
