Casillas' verdict, Ronaldo or Messi?

Iker Casillas coincided with Cristiano Ronaldo at Madrid and won several titles with the Portuguese forward. He shared a locker room with him for several years and knows his character very well.

He has faced Leo Messi in countless matches, a beast who made the goalkeeper suffer on several occasions in the 'Clásicos' between Real Madrid and Barcelona. He analysed this debate in his latest interview with ESPN.

"People may not know Cristiano. I do know him, even in private. They would be surprised. Cristiano is a voracious player, who is hungry. He wanted to be the best since he was a child, and he has succeeded," said Iker Casillas.

"If you compare him with Messi, what Cristiano has done is perhaps more valuable than what Leo could have done, whose talent you can see," he added.

He made a more global impact: "We have been lucky enough to enjoy two spectacular players. Cristiano, if people do not know him, can seem overpowering or self-centered. I have nothing but good things to say about him, he's just the opposite of that".
