Ahead of Portugal's Nations League final clash with Spain, Ronaldo told reporters: "You know I have a lot of affection for Argentina, my wife is from there.
"I have already been invited to play in the Club World Cup for an Argentine club. You never know⊠the time is there. I am already 40 years old, but you never know. But I think it is very difficult. I have never been to Argentina, I want to go, I have a lot of affection for the Argentines."
