Chelsea are demanding a world record fee from Chinese clubs if they want Diego Costa.
The Sunday Times says they want £130million for Costa – as it emerges Oscar has been secretly encouraging his Brazil team-mate to move to China.
The Blues believe they settle a world-record transfer fee for the striker before the year is out.
Oscar informed Costa of his colossal £21m-a-year -after-tax salary.
And they claim the Brazilian believes he is significantly underpaid compared to other key players at the club.
But rather than improve his terms, Blues bosses “are understood to have asked agents to find a Chinese club willing to pay £130m or more for him".
