Real Madrid legend Ronaldo believes the game today lacks superstars.

Ronaldo says there isn't enough players in the class of Barcelona ace Lionel Messi and Cristiano Ronaldo.

"Just as Zinedine Zidane says, I think Messi is incredible, Cristiano Ronaldo is amazing, Neymar is incredible, but football in the world today is devoid of 'cracks'," said Ronaldo.

Ronaldo says he remains in regular contact with former Real teammate Zidane.

"He is my friend and we talk a lot about football today. Today he is a coach, one thing I do not want in any way. The pressure is the same, but it is different to being on the pitch."
