Ronaldo from Brazil is the only real Ronaldo. CR7 is the second best player atm, but hardly even in the top 20 of all time.
Ronaldo on the other hand is easily in the top 5.. after Zidane, Pele and Maradona. the other person in the top 5 is highly debatable... (müller, messi, beckenbauer, best, cantonna, platini, raul, ronaldinho.. you take your pick.)
