Legendary Brazil striker Ronaldo believes that Neymar could become the "best player in the world" if he leaves Santos and moves to Europe.
Neymar, 19, has been openly courted by Barcelona and Real Madrid for a number of months and has been heavily tipped to complete a switch to Spain in 2012, though he has denied that an agreement has been reached with either club.
However, Ronaldo - who moved to Europe at the age of 17 and enjoyed notable success with PSV, Barcelona, Real Madrid and Inter Milan - thinks that leaving Brazil could be the making of Neymar.
"Leaving aside selflessness and patriotism, Neymar has to look at the things which will help him conquer the world,'' Ronaldo told ESPN. "If he can play in Europe the way he does in Brazil, very soon he would be the best player in the world.
"I cannot decide for him. But it is clear that if Neymar came to me for advice I would say the best thing is to go to Europe and choose the best team for him."
Ronaldo and fellow 2002 World Cup-winner Roberto Carlos have regularly repeated their belief that Neymar needs to move to Europe in order to fulfil his vast potential, with Carlos insisting last week that his former club Real Madrid would be an ideal destination for the young forward.
"I hope Neymar is intelligent and is not just limited to Brazil," Carlos said. "I told Neymar to stop messing around and join Real Madrid when I spoke to him last week.
"I said he ought to sign for them now. However, he is like a superstar in Brazil and people are stopping him from leaving. Neymar is like the Cristiano Ronaldo of Santos - a leading player, but I hope he signs for Madrid."
