Mega rich Chinese club Tianjin Quanjian have confirmed they are “still working” on a deal to sign Diego Costa.

Mirror Sport revealed on Wednesday the Chinese Super League club are willing to pay Costa £650,000-a-week AFTER TAX and the fear at Chelsea is that may be affecting his form and the reason behind his goal drought.

Tianjin Quanjian billionaire owner Shu Yuhui told Sina Sports: “I can only say that we are still working on the deal [to sign Costa]. And we have already made contacts with several players.

"We have high standards [in buying foreign players] and those players prefer top clubs such as Bayern Munich and Real Madrid.

"It's safe to say that we have the same transfer targets as those illustrious clubs.

“We may have to pay bigger price because our club are now competing with Real Madrid and Bayern Munich.”

Tianjin Quanjian tried to sign Costa in January in a stunning £90m deal with the belief among the Chelsea players that the Spain international will go in the summer.
