Chelsea prepared to sell Diego Costa this summer.
The Chinese Super League side Tianjin Quanjian is back in for the Blues striker and wants him this summer.
And Chelsea is willing to let Costa leave.
They say Tianjin Quanjian is still willing to pay the £90m that they offered in January for the 28-year-old.
However, manager Antonio Conte will only let his star man leave when they complete the signing of Real Madrid star Alvaro Morata.
