The 29-year-old believes his work ethic sets him apart from other players, while adding he is determined to win a tournament with Portugal before he ends his careerReal Madrid star Cristiano Ronaldo says sheer hard work separates the greatest players from the good in world football.
The 29-year-old won his second Ballon d'Or in January and lifted the Copa del Rey on Wednesday night - albeit having watched on from the stands with injury - to add to his sizeable silverware haul.
And the former Manchester United man has credited his incredible work ethic behind his extraordinary consistency.
He said: "I've always watched the players who had the best performance and realised one thing: what makes the difference between good players and stars is the work.
"The difference between good players and best players can be in those details."
Ronaldo has often been criticised for possessing an arrogant streak, but though he readily admits to making mistakes, he remains confident he is a better person and footballer than his younger self.
"I've made mistakes but I'm happy to have committed to my craft," he added. "I've become a better player and a better human being.
"I always want to be the best and I always want to be successful, that never changes. I put pressure on myself to perform."
The forward added that experiencing success with Portugal remains one of his unfulfilled dreams and would "cap off a great career".
