Should Ronaldo go to the world cup (BRAZIL)?

I think he should go as a sub like you said. First he can add you his career goal lead in the World Cup. Second he can a some experience in the Brazil line-up, I believe that it is a fairly young club with a few on the squad that have any Cup experience. Finally I feel that it could be a motivational factor for both him that he can still play at that level and the team that they have someone with the experience.
