The Portugese striker was the subject of taunts by the crowd during his national team's 4 - 0 win over the minnows back in September.
The name 'Messi' was constantly chanted throughout the match, referring to the intense club rivalry between Real Madrid's Ronaldo and Barcelona's Lionel Messi.
"It is the same thing if they sing that kind of chant or if they stay quiet," he told TF1. "Those chants do not provoke me, nor do they make me change my way of playing.
"I do not care about them."
The 26-year-old was adamant that his role in his current club, Real Madrid, comes first over his nomination for the 2011 FIFA Ballon d'Or award.
"I do not know if I will win the award or not," he added. "Madrid are doing well, I am doing well, too, and my national team will go the European Championship. So I am happy.
"The Ballon d'Or is not my priority, nor does it concern me now."
Ronaldo also denies the recent rumours of him leaving his club for a move to a wealthy Paris Saint-Germain.
"I know they are a great club, but I am not leaving Madrid. I am sure about that."
