His agent admits the Italy international is attracting big club interest.
"Alessandro is loved in Bologna, but there could be some important opportunities for him in the summer," Luca Puccinelli told Sky Sport Italia.
"If a top team came in for him then that would be a really big opportunity.
"In Italy or abroad? If he stays on the peninsula then that would help his international career as he would be seen more regularly.
"But if a major Champions League side made an offer then it wouldn't be very intelligent to not consider such an option."
