Cristiano Ronaldo's nickname for Lionel Messi is "motherf**ker"

Saying "Messi" or saying "motherfucker" is the same for Cristiano Ronaldo. That's what journalist Guillem Balague has revealed in his new book. 

It's a very different tone than Ronaldo usually refers to Messi publicly in. 

Ronaldo uses this nickname for Messi in the Real Madrid dressing room. There, his team-mates make a joke about the Argentine, as explained by Balague. 

"The players refer to Messi as Cristiano Ronaldo's small dog, to be put in his designer handbag."

This is not a creative nickname. It's just an insult. 

Furthermore, it's extended to any other Real Madrid player seen speaking to Messi.
