Brazilian-born Deco, 32, recently indicated he wanted to return home to be with his ill son.

He recently told Brazilian newspaper Lance: "It's been 13 years since I left Brazil for playing in Europe. Now I want to go back home and play in my country because I have never been able to win a title there."

Fluminese, based in Rio de Janeiro, will be delighted with the signing of the midfielder who made 28 appearances for Chelsea last season.
