Brazil coach Carlos Alberto Parreira insists he will keep faith with Ronaldo and his side's attacking style against Australia on Sunday.
The reigning champions were less than convincing despite a winning start to the defence of their trophy in their 1-0 victory over Croatia, and Ronaldo in particular was virtually static.
"Ronaldo has not been playing for the last two months and has had only two friendlies so it was natural he felt a bit heavy as it was very hot, but I'm sure he will improve as the tournament goes on," said Parreira.
