New Chelsea boss Villas-Boas has told owner Roman Abramovich that a defender, who can operate anywhere across the back four, is his No.1 priority and he has made the Real Madrid and Spain star his top target.
World Cup winner Ramos is reportedly furious with Bernabeu chiefs after they failed to deliver on their promise of a salary hike and Villas-Boas is keen to pounce.
Real value the 25-year-old, who still has another two years on his contract, at around £80million.
But sources close to the club believe they would give serious consideration to offers of around half that figure. Villas-Boas will tell Abramovich that is good value for a player who could form the backbone of the Chelsea side for many years.
