Chelsea are prepared to sell Diego Costa to China this summer.

The Daily Star says they have slapped a world record asking price on Diego Costa, according to French journalist Johnny Severin.

The SFR reporter says Antonio Conte wants £127m for Costa and has already rejected an offer worth £90m.

Chinese Super League club Tianjin Quanjian are the interested party - and they are said to be prepared to smash the world transfer record to make the deal happen.

Severin tweeted: "Revelations @SFR_Sport. The Chinese offer XXL that @ChelseaFC refused to retain @diegocosta… against his will.

"Huge Chinese offer which attracted @diegocosta but declined by @ChelseaFC.

"Tianjin has been told by @ChelseaFC to come back in summer with a €150M (£127m) offer to sign @diegocosta The Chinese club intend to do so.

"@ChelseaFC declined €107m offer (£90m) from #Tianjin. @diegocosta was attracted by huge offer: €100M [wages] for 3 seasons."
