RIO DE JANEIRO -- Ronaldinho is set to sign with a Chinese or US-based club in what could be the final contract of his decorated career, his brother and agent said on Friday.

The 36-year-old former Barcelona star has not played competitively since ending a disappointing two-month spell with Rio de Janeiro outfit Fluminense last September.

Roberto Assis, who has managed his brother's affairs throughout his entire career, said Brazilian clubs had been "ruled out" of the reckoning for the playmaker's next move.

"The probable destination for him is Major League Soccer in the US or the Chinese Super League," Assis told Brazilian news portal Uol.

Ronaldinho, who twice won the FIFA world player of the year award, will make a one-off appearance for Las Vegas City next month in their friendly against Miami United.
