Maldini, 24, scored twice in 14 appearances during a loan spell at Lazio in the second half of last season, and his parent club Atalanta are already weighing up options to find him a new home this summer.
Maldini's registration belongs to Atalanta, who are working to resolve his future as quickly as possible ahead of the new campaign.
The forward looks set to be one of the more active storylines of the summer market, with SportMediaset reporting that two clubs have positioned themselves to sign him.
Parma and Sassuolo have both shown concrete interest in bringing in the attacker, setting up competition between the two Serie A clubs for his signature.
Maldini's loan spell at Lazio offered glimpses of his quality without ever delivering the consistent breakthrough some had hoped for, leaving Atalanta in a position where finding the right next step for his career has become a genuine priority heading into the summer window. Whether that next step comes via Parma, Sassuolo or another interested party remains to be determined as talks progress.
The son of AC Milan and Italy great Paolo Maldini, the forward has spent much of his career searching for a club where he can establish himself as a genuine first-team regular, with loan spells already forming a familiar pattern since his early years in professional football. A permanent solution, rather than another temporary arrangement, would represent a significant step toward settling that uncertainty once and for all.
Both Parma and Sassuolo are understood to view Maldini as a player capable of adding creativity and unpredictability to their respective attacks, with his technical ability rarely in question even as his career has struggled to find consistent footing at the highest level of Italian football.
