"I don't doubt that I will go down in footballing history. Whether people like it or not, the numbers speak for themselves. I will be up there with the rest," Ronaldo, 31, told the UEFA website (www.uefa.com) in an interview.
"Some like it more, some like it less, but I have no doubt that I'm already in the history of football.
"I always felt that I was a special player... I've always worked hard, believed in my potential and I've developed more and more as a player, as a person, as a human being."

Ronaldo has 16 Champions League goals this season, the most by any player in a single campaign, which has propelled 10-times European Cup winners Real to a semi-final with Manchester City.
The Portugal international, who missed last week's goalless first leg, will aim to extend his scoring record on Wednesday when Real and City battle at the Santiago Bernabeu for the right to face Atletico Madrid in the final in Milan on May 28.
"It's a privilege to know that I'm the leading goalscorer of all time in the Champions League. Obviously, I feel very happy at having achieved that," the 31-year-old said.
"It's a special competition and a competition that Real Madrid love. I've been lucky enough to win it twice and obviously I want to win it more -- hopefully again this year."
