Manchester United are favourites to sign the Serb.
“We'll see the conditions that line up," Lotito told Sky Sport Italia.
“Milinkovic has a good rapport with the club, just as the club has with him. If some offers were to be presented, we'd evaluate them with a spirit of collaboration that looks after the interests of the club and the player.
“We'll make the decisions that are best for everyone. The investments we made last summer should've allowed us to qualify for the Champions League, but we hope to have learned from the experience."
