The Brazilian side hope to return one of their former players back to the club.
Fluminense hope to sign Thiago Silva from Chelsea as a free agent next summer.
Silva started his career at the Brazilian side before joining Milan to start his successful spell in European football.
After eight years at Paris Saint-Germain, Silva joined Chelsea in 2020. Growing competition in the Blues’ backline has limited the 38-year-old’s playing time at Stamford Bridge.
As Silva spends the final months of his contract, Fluminense has emerged as one of his main suitors in the market.
Speaking at a press conference, Fluminense president Mario Bittencourt said: “We are waiting for [Thiago Silva’s] decision at Chelsea. We don’t know yet if he will extend there or not.”
“Depending on this information, whether he extends or not, we will start discussions for him to come back to Fluminense.”
Another experienced defender, Marcelo, is also a product of the Brazilian club. After ending his glorious career at Real Madrid, Marcelo joined Olympiacos in September. But Bittencourt says Fluminense are also considering a move for the Brazilian left-back.
He added: “We have the will to bring [Marcelo] in. But he is in the same situation as Thiago Silva. He has a contract in Greece that goes until May.
“We are waiting to see the decision he will take there, if he will extend or not. There was a report that Al-Nassr, the same club as Cristiano [Ronaldo], were interested in him.
“We are following the situation of Marcelo and Thiago Silva to bring them back.”
