But Tianjin released a statement on Thursday denying any discussions have yet taken place with Chelsea or Costa about signing the striker.

It read: "With regards to the current widespread rumours of Chelsea player Diego Costa joining Tianjin Quanjian, the club would like to make clear that no discussions have taken place regarding the transfer of Diego Costa."

Sky Sports News HQ understands Costa remains Tianjin's first-choice target after their previous attempts to lure the player to Asia failed at the start of the year.

Despite missing out then, they are willing to more than quadruple the Spain international's wages and make him the world's best-paid player.

The Chinese transfer window opens on 19 June and it is thought Tianjin would look to complete a deal for Costa then.

The striker is contracted with Chelsea for another two years.
