The 20-year-old's move comes just eight months after he was signed for Blues by former manager Gianfranco Zola on a three-and-a-half-year deal.
It is a second spell in Italy for the Mali Under-20 international, who was previously with Serie B side Virtus Entella before making the switch to St. Andrew's.
Since making his Blues debut in the home win against Fulham in February 2017, he has gone on to make 11 appearances for the Club.
However, he has figured just once this season, in the opening day league defeat away at Ipswich.
