The 35-year-old striker has been without a club since being let go by West Bromwich Albion after using an anti-Semitic gesture.
Atletico Mineiro has confirmed the signing of former France international Nicolas Anelka on a free transfer.
The 35-year-old has been without a club since being let go by West Bromwich Albion last month, after already announcing via social media that he was terminating his contract with the club.
According to Atletico Mineiro president Alexandre Kalil, the forward has now agreed to join the Copa Libertadores champions.
"Anelka is a rooster [a reference to the club's nickname]," Kalil wrote on his official Twitter feed.
Anelka's West Brom exit was sparked by the controversy caused by the striker's use of the "quenelle" gesture to celebrate a goal against West Ham United at Upton Park in December.
The act, which is widely seen as anti-Semitic, resulted in the former Arsenal, Paris Saint-Germain and Real Madid man being banned for five games by the Football Association.
