Iker Casillas picks Cristiano Ronaldo over Lionel Messi

Real Madrid goalkeeper Iker Casillas has insisted that he would not swap Cristiano Ronaldo for Lionel Messi.

The pair are widely regarded as the best two players in world football, but the Spanish number one has refused to entertain suggestions that Messi is superior.

"I'd choose Cristiano over Messi because he's a player who gives us so much every season and he's a player I spend time with every day," Casillas told Cadena Cope.

"I know him, know who he is, know how he trains, know what he wants and where he wants to get to."

Ronaldo has scored 160 goals in 155 games for Madrid.
