The Chinese Super League side have been linked with Chelsea star Diego Costa and Borussia Dortmund ace Pierre-Emerick Aubameyang in recent weeks.
The Blues forward almost moved to the Far East in January and his future at Stamford Bridge remains up in the air.
Chelsea are said to be interested in Romelu Lukaku and Alvaro Morata as possible replacements for Costa.

“We have secured a verbal agreement with the player as well as his club”

“Basically, a decision on which player we are going to buy in the summer has been made. And we have secured a verbal agreement with the player as well as his club,” Tianjin Quanjian owner Shu Yuhui confirmed.
“We have not signed a formal contract yet, and I will not reveal the player’s name during the sensitive period.
“The club have once got the short end of the stick after our transfer target was exposed ahead of time. So we won’t say his name.
“We will get [at least] one, but two [signings from Europe] is also possible.
“Buying a world-class centre forward is a no-brainer, but a winger is in our plan too. The dust has not settled yet, but we are close to reaching a deal [with the winger].”
Costa has been in stunning form for Chelsea this season, scoring 20 goals to help the Blues win the Premier League.
