New York Cosmos signing Raul says Real Madrid star Cristiano Ronaldo could become the greatest of all time.
Raul is a former Real captain.
Speaking with BBC Sport, Raul said "Cristiano and Messi are at the top" but that "it is difficult in football to say which players are first, second or third."
He then assured that it will be a lot easier to choose the all-time number one "if Cristiano carries on the way he is."
