Brazil's star striker Ronaldo will be fit and ready to face Croatia in his country's World Cup opener, having suffered with blisters in the last week.

The Real Madrid ace had been reported to be a doubt for the game in Berlin next Tuesday, but team doctor Jose Luis Runco says there is no problem.

He commented: "The healing is almost complete. He won't have any more problems.

"From what he said, maybe the type of stitching of the new boots was bothering him.

"We are very comfortable. There is nobody with complaints and the players are all at the right level of fitness."

Meanwhile, Selecao playmaker Ronaldinho has warned his team to expect their opponents to pack their defence in a bid to stifle Brazil's attacking potency.

He added: "All nations try to set up the best defence in the world when they are facing Brazil.

"We know we will face a lot of difficulty because of that. Everybody plays very defensively against Brazil."
