Impressive performances with Guangzhou Evergrande and Brazil
have seen Paulinho's stock rise over the past year, so much so that even Barcelona have expressed an interest in signing him.
The player revealed that a proposal has been made, although he wasn't sure if he would ultimately end up at the Camp Nou.
"There has been contract with my agent," he confirmed in an interview with Globoesporte.
"There was an offer and I know that we're talking.
"I am currently at a very happy stage of my life and my career.
"It is difficult to decide [what to do] at a moment like this."
That said, the 28-year-old admitted it would be hard to turn down an opportunity such as this.
"I am very happy that a great club like Barcelona is interested in me, as that is priceless," he added.
Paulinho has been playing in China since 2015, when he left Tottenham to move to Guangzhou.
