Konigstein: Under-pressure Brazilian striker Ronaldo insisted on Thursday that his World Cup campaign will not be derailed by his latest worrying health scare.

The Real Madrid attacker, who has been dogged by injury and fitness problems, needed treatment at a Frankfurt hospital after complaining of dizzy spells.

But the 29-year-old said he has been given the all-clear and is fit to play in the world champions' next World Cup Group F clash against Australia in Munich on Sunday.

"This is nothing like what happened in 1998," said Ronaldo referring to the infamous fit in the dressing room he suffered just before kick-off in the final against France in Paris which his side eventually lost 3-0.

Earlier Thursday, the Brazil Football Confederation (CBF) had said that the tests showed nothing wrong with the player.

The CBF said on its website that he had started feeling unwell on Wednesday evening after the Brazilians had returned to their plush Konigstein (western Germany) base following the 1-0 win over Croatia in Berlin.

The Brazilian medical team whisked him off to a Frankfurt hospital, but he returned to join the squad after medical tests cleared him and he trained on Thursday.

Ronaldo was the star of the last World Cup in Japan and South Korea, scoring both Brazilian goals in the 2-0 win over Germany in the final.

But his form has slumped over the last year as he has struggled with weight problems and he is expected to leave Madrid during the close season.

He was widely criticised for his lacklustre performance against the Croatians on Tuesday where he was substituted in the second half and replaced by Real Madrid teammate Robinho.

However, coach Carlos Alberto Parreira has said he intended to play him in the world champions' next game against Australia on Sunday.

Australian defender Lucas Neill, who will be one of the players handed the job of marking Ronaldo in Sunday's game in Munich, said the Socceroos were not paying much attention to the saga and expected the striker to play.

"He's always dangerous. All the players on their day they can do anything and Ronaldo is no different and we are going to give him the respect he deserves, but not too much," said the Blackburn player.

"I think he's got a bit to prove, in his first game he was criticised, so he'll probably come out and give his best," he said.

Ronaldo needs just one goal to move ahead of Pele as Brazil's top all-time World Cup goalscorer. Both currently have 12 two behind all-time goal leader Gerd Muller of Germany.

"I feel fine and I'm thinking only of the match against Australia," he said.
