The 1994 and 2002 World Cup winner has taken the time to praise the former Santos man and has admitted the organisation has disappointed the people of Brazil
The 37-year-old believes Brazil, who face Croatia, Mexico and Cameroon in Group A, come in with more confidence than the victorious 2002 team he was a part of and thinks home advantage will be a huge advantage.
"Brazil are entering the World Cup with much more confidence than we had when we entered the World Cup in 2002," Ronaldo told reporters.
"I believe that the squad we have for 2014 is really strong. We have a balanced team, full of a lot of talent.
"Neymar is a fantastic kid, so talented, he is our great hope for the future.
"Another thing is that we are playing at home, this makes me really wish I were a few years younger and 45 pounds lighter. This is a once in a lifetime opportunity. Playing at home in front of our fans."
Ronaldo is in danger of losing his goalscoring record to Germany international Miroslav Klose, who has netted one fewer World Cup goal with 14, but he hopes his name will remain in the record books a little longer.
"I wouldn't say that I am not sleeping because of the chance of Klose breaking the record, but I am sending some bad towards him, perhaps just a little.
"My friends and fans are doing the same. However, whatever I do doesn't really matter, records are made to be broken by others.
"I don't have this ambition of being the biggest scorer forever, I don't think it is possible to do that."
Ronaldo then went on to admit he is ashamed the local organising committee have only delivered on '30 percent' of what they promised.
Delays in stadium construction, infrastructure issues and protests have marred the lead-up to the World Cup, which starts on June 12.
"I'm ashamed for the Brazilian people who were expecting big investments and a great legacy for them, for us.
"We promised to rebuild airports and improve transport and infrastructure. I am sorry for all the things we promised and have not completed.
"We have some numbers - only 30% of all the things that were promised will be done in time for the World Cup to get underway. That number is my only concern, for that I'm ashamed.
"The Brazilian people are the ones affected by our failure."
