Serie A champions Juventus have made the striker available but the Biancocelesti are more concerned with holding onto key players Antonio Candreva and Senad Lulic
The former Cagliari striker has been deemed surplus to requirements in Turin following the summer arrivals of Carlos Tevez and Fernando Llorente, with both Lazio and AC Milan reportedly registering an interest in the Italian.
But Lotito insists the Biancocelesti will not be making a move for the 28-year-old striker, whose current deal runs until 2017.
"We have never negotiated for him," he told Sky Sport24. "He is not our objective, for a number of reasons."
Lotito explained that his primary focus at the moment is holding onto Antonio Candreva and Senad Lulic, both of whom have been linked with moves away from the Stadio Olimpico.
"We want to strengthen the team and not weaken it," he declared. "We rely on [Candreva], as well as on Lulic.
"We have rejuvenated the squad, trying to find a mix of experienced players and young players that can attain the mentality of a great team."
Lazio only finished seventh in Serie A last season but ended their campaign on a massive high by beating city rivals Roma in the final of the Coppa Italia.
