Not the Portuguese one either, the proper Brazil and Real Madrid version.
The World Footballer of the Year has previously worked with Sir Bobby at PSV and Barcelona and was the target of cheeky loan bid when during Robson’s first season at St James’ Park.
According to the Sunday Sun Ronaldo told Spanish newspaper El Mundo Deportivo: "Bobby Robson is like a father to me.
"I don't discount signing for Newcastle one day. First, I want to win many titles with Madrid but later I would like to play in England."
It’s worth noting that the comments originally appeared in a Barcelona based publication that delights in anti-Madrid stories.
But on the subject of fantasy signings Sir Bobby is also alleged to rate Porto playmaker Deco and to have described Juventus’ Pavel Nedved as the best player in the world in his position.
We can dream!
