With the next transfer window just a few weeks away, Bologna are yet to extend five of their players.
Twenty-nine-year-old goalkeeper Federico Agliardi has appeared in 16 matches this season, but would have the option to open talks with another club in January if another deal is not offered to him.
Defenders Archimede Morleo and Daniele Portanova are also approaching the last six months of their current deals.
Twenty-nine-year-old Morleo has appeared in 13 matches, while 33-year-old Portanova has appeared in none.
Thirty-two-year-old Uruguayan midfielder Diego Perez and 30-year-old Andrea Pisanu are the other two players yet to be extended past their current deals.
