Brazil striker Ronaldo has returned to training on Thursday after visiting a clinic on Wednesday complaining of dizziness and headaches.
The Brazilian football association (CBF) said the 29-year-old underwent a medical check-up during the visit.
The CBF website said: “No abnormality was found. Ronaldo is, therefore, in normal conditions for training.”
Ronaldo came in for heavy criticism following his performance in Brazil’s 1-0 victory over Croatia in their World Cup game on Tuesday.
The Real Madrid striker was poor against the Croats and was jeered when he was replaced by Robinho after 69 minutes.
Brazilian media criticised the Real Madrid striker for his display, with former Brazil striker Tostao calling his performance “weird”.
He was hindered by a series of nagging injuries during the past season, and his last game for them was on 8 April, when he limped off after one hour with an injury to his right thigh.
But Brazil coach Carlos Alberto Parreira has said he will start with Ronaldo again in the team’s next match against Australia on Sunday. According Parreira, Ronaldo’s lack of fitness is due to his recuperation from his injury near the end of the season. He also suffered blisters on his feet and a fever in the build up to the finals.
Nonetheless, according to the Braziilian press, his have team-mates have long been worried about the striker’s poor pace.
Jose Roberto Torero, in the Folha de Sao Paulo, wrote: “Ronaldo was unrecognisable. He didn’t even run to get back onside. When Brazil attacked he was useless. Our magic square became a triangle.”
“When Robinho substituted him in the 69th minute, the biggest difference was that Brazil finally started to play with 11 men. Perhaps the best that can be said about our team was than they won when they were down to 10.”
The striker is only goal short of surpassing Pele as Brazil’s all-time leading World Cup goalscorer and two goals will see him equal Gerd Muller as the leading scorer in finals.
Ronaldo’s team-mates have been backing him. Yesterday Cafu told Brazilian TV: “Ronaldo is calm and serene and full of desire to show that he is the striker that the world wants him to be. He is very important for us.”
