Spanish TV station Cadena Ser claim Chelsea forward Diego Costa has signed a pre agreement contract with Chinese Super League club Tianjin Quanjin.

Costa was spotted with agent Jorge Mendes and four other gentlemen in the Far East last week, and it is believed these men were representatives of the Chinese club.

28-year old Costa will earn a reported £25million a year in China, and will play alongside former Chelsea player Alexandre Pato and Belgian midfielder Axel Witsel.

The report also suggests that Chelsea will receive a transfer fee of around £76million.

The Express speculates that the Blues could replace Costa with Antonio Conte favourite, Real Madrid's Alvaro Morata.
