Ronaldo will be fit for Brazil’s World Cup opener against Croatia on 13 June, despite struggling with a mystery foot problem.
Ronaldo has been using some old boots as it was thought new ones were causing blisters and pain, but the problem persisted.
“The healing is almost complete. He won’t have any more problems,” said team doctor Jose Luis Runco.
“We are very comfortable. There is nobody with complaints and the players are all at the right level of fitness.”
The 29-year-old, who was the top scorer at the 2002 finals, is two goals short of becoming the all-time leading scorer in Worlf Cup finals.
