Rumoured CSL target Mascherano is tipped to leave La Liga giants Barca, having recently spoke of his time at Camp Nou coming to an end.
With game time hard to come by under Barca head coach Ernesto Valverde, the 33-year-old has been linked with a January move to China, where Tianjin have reportedly made an offer for the Argentina international.
However, Tianjin – now led by former Fiorentina boss Paulo Sousa following Fabio Cannavaro's return to Chinese champions Guangzhou Evergrande Taobao – denied those reports, pointing to Mascherano's age.
"Those [rumours] are untrue. We have not entertained the idea of buying Mascherano at this point," a Tianjin spokesperson told Tianjin Today Evening News.
"We will aim to get better results next season and Mascherano is too old to fit in at our current plan."
Mascherano, who is recovering from a hamstring injury, has only made six La Liga appearances this season and 10 in all competitions.
The Argentine made it clear in late November that he thought his time with Barcelona was done, telling ESPN: "I think that my stage here is ending. It makes sense that after such a long time there's not much more I can do in this club.
"I'm not saying it with a heavy heart. I've had the best years of my career in this club. I'll never forget it."
