The 27-year-old has transferred to his sixth club in Italy after struggling for game time at Stadio Artemio Franchi
Ghana international Joseph Alfred Duncan has left Italian Serie A side Fiorentina for Cagliari, both clubs have announced.
The midfielder joins Cagliari in a deal lasting until the end of the season, with an option of a permanent move at the end of the spell.
This 2020-21 term, he has made a paltry four league appearances for Fiorentina, prompting his move away in his search for more playing time.
