DiarioSport says Ronaldo is No1 on Barca's shopping list should they choose to cash in on fallen Brazilian superstar Ronaldinho.
Despite Real's aggressive push, Barca will count on their good relationship with Ronaldo's agent, Jorge Mendes, to win any potential battle for the Portuguese's signature. Mendes boasts Barca stars Deco, Rafael Marquez and former players Thiago Motta and Ricardo Quaresma on his books.
At FIFA's World Player of the Year awards in Zurich last month, Ronaldo admitted: "Spain is a fantastic competition, very attractive, where very attacking football is played."
He added: "Only God knows the future, but I would like to discover the difference between playing in England and Spain."
