The Selecao legend believes that the Barca star will be one of the greatest South Americans ever if he continues on his current track
The 21-year-old has shone in 2013 - after signing for the Catalans from Santos in the early summer, he starred as the Selecao stormed to the Confederations Cup title and has subsequently starred for Gerardo Martino's men this season.
"It is a fact that Neymar will be a great player," Ronaldo told Brazilian television. "He will go down in history as one of the best Brazilian players in the world.
"He's on the right track. He's a charismatic player and is focused on what you have to do to succeed."
The Blaugrana are in the midst of a winter break but they are back in action against second-placed Atletico Madrid, who are level on points with the club.
