Fluminense have confirmed the news that Marcelo will return to the outfit after 17 seasons away.
After a hugely successful spell with Real Madrid where the defender secured six LaLiga wins along with five Champions League titles among others, the 34-year-old left-back had a brief and ultimately unsuccessful spell with Greek top flight side Olympiacos.
His term with the Piraeus based Greek side ended after just five months with both sides agreeing to terminate the existing deal.
Marcelo is the eighth 'Flu' reinforcement for the 2023 Serie A season after the club signed left-back Jorge, striker Keno, midfielders Lima and Giovanni, right-back Guga, defender Vitor Mendes and goalkeeper Vitor Eudes.
Marcelo's deal with the Brazilian club runs through to December 2024, with an option to renew until the end of 2025.
