The 27-year-old has divided the opinions of fans all over the world, and often receives hostile receptions from opponents' supporters.
"Not even God can please everyone. I always try to be a good person who the majority of people like. But showing too much humility is a flaw. People either hate me or love me," the attacker told Globo.
"I always try and work hard in order to be the best at what I do. In my opinion, everybody should have the objective to be the best at what they do, regardless of his or her profession."
Meanwhile, former Portugal coach Luiz Felipe Scolari has nothing but praise for the player, and feels that he deserved to have been recognized as the world's best on more than one occasion.
"He's a player who always wants to win. He never wants to come second, but always wants to be the best. He's a very complete player and always professional," Scolari said. "For me, he should have won the FIFA Player of the Year award at least three times."
The Portugal international is one of three players still in the running for the 2012 FIFA Ballon d'Or alongside Andres Iniesta and Lionel Messi.
