Ex-Juventus and Watford defender has reportedly signed for Charlton Athletic.
Sky Sport Italia claim the 29-year-old put pen to paper on a contract that will expire at the end of the season.
He was a free agent after the spell at Watford came to an end in July 2015 and was training with QPR to maintain his fitness levels.
Motta is well-travelled, having played for Atalanta, Juventus, Udinese, Torino, Roma, Catania, Bologna, Genoa and Watford.
