Costa is again being linked with a move to Tianjin Quanjian this week.
Tianjin are reportedly ready to make the Spain striker the highest paid player in world football by offering him a staggering £650,000-a-week deal, after tax.
And now Antonio Conte's premier striker might also be following suit with Shu Yuhui, the billionaire owner of Tianjin, claiming that a deal for the Spanish striker is being worked on and could be finalised in the next transfer window.
Former teammates Oscar and Ramires have already made the move and are enjoying the fruits - and by fruits we mean money - of China.
"In the meantime, these players show more interest in joining the clubs like Bayern and Real Madrid". It's safe to say we have the same transfer targets as those illustrious clubs.
Although Costa has managed a reasonable return of 17 goals from 30 Premier League games this season, only three of those strikes have come in 2017 and his poor form in front of goal has been partially responsible for Chelsea's recent wobble.
"We are literally grabbing players with Real Madrid and Bayern".
The Spain worldwide was the subject of interest from the Chinese Super League in January, though the Blues turned down an £80million offer for his services at the time.
Whether that's with or without Costa remains to be seen, but one thing is for certain.
The Chinese Super League runs from March to November and the transfer window from June 19 to July 14 is their equivalent to the Premier League's January transfer window.
