World Cup winner Marcus Cafu has warned Real Madrid starlet Vinicius Junior to stay grounded.
The Brazilian legend indicated that the 18-year-old forward would have to work extremely hard to meet Los Blancos' high demands.
"What Vinicius is doing is not a surprise to me, as we knew about his potential," said Cafu to Marca.
"He is not Cristiano Ronaldo and there is still a lot of difference between the two, as Cristiano made history at Real Madrid and Portugal.
"Vinicius, however, has what it takes to create history at Real Madrid.
"He has to be focused on football, have commitment and ambition.
"Great players always have to demonstrate something else and can't lose focus.
"He's responsible, as Brazilian players are accustomed to wanting to assume that kind of responsibility and particularly in clubs as big as Real Madrid."
