He has immediately joined up with his new team-mates in Philadelphia.
“I’m really happy to be here,” said Calafiori. “I waited a lot.
Calafiori, who spent one season at Bologna, can play as a central defender or at left-back – and has previously played on the left wing.
He played 30 times for Bologna in Serie A last season, scoring two goals and recording five assists as they finished fifth to seal a Champions League spot.
