Ronaldo has scotched speculation linking him to a possible move to European Champions' Real Madrid from Inter Milan.
"Real Madrid are a great team, one of the most important in the world, but it has its players, and me I'm already part of a team at Inter," Brazil's two-goal World Cup final hero told the Spanish sports daily Marca.
"For a long time now [Inter Milan] president Moratti has had confidence in me, and I am totally loyal to him.
"When I was experiencing very difficult times, being injured on a number of occasions, the president was always by my side and I can't betray him."
Ronaldo is taking time out wth his family back home before returning to prepare for the new season in Italy.
"I want to forget everything until my return on August 5," he insisted.
"In the meantime I'm going to enjoy my first holiday for some time."
Ronaldo's name was linked to Real Madrid earlier this week. His Brazilian teammate Roberto Carlos, also his roommate, was reported in the Italian press as having asked his president at the Spanish club Florentino Perez to sign the man who scored eight goals in seven matches at the finals.
Ronaldo's brace in the final at last wiped away the traumatic memories of the 1998 final against France when he suffered a fit hours before the match and was clearly below par during it as the French ran away 3-0 winners.
