- Ambitious Tianjin already have Brazilian forward Pato and Belgian international midfielder Axel Witsel on their books.
- They were previously linked with striker Diego Costa, who is now at Atletico Madrid after leaving Chelsea.
Tianjin Quanjian have threatened legal action in a bid to stamp out speculation that Barcelona captain Andres Iniesta will soon be joining the Chinese club.
The 33-year-old Spain midfielder has been linked with a summer move to the Chinese Super League (CSL), which has attracted a number of big-name foreign players.
Veteran defender Javier Mascherano left Barcelona in January for Hebei China Fortune, joining the likes of the Brazilians Hulk and Oscar in the CSL.
But Tianjin moved to quash the rumours about Iniesta, issuing a statement saying: "Our club solemnly state that such news reports are false."
