Vieri could make a return to Bergamo if Osti has his way in the coming weeks, as he revealed that the now former Fiorentina player is one of his main transfer targets for this summer in order to strengthen the forward line.
"There is a technical project which sees Vieri part of Atalanta next year," explained the director of sports.
"I must build a team which is capable of survival," he added, even though all other negotiations have stalled for the time being.
Many names have been linked to the Nerazzurri lately, but for the time being no transfers have been registered.
However, Osti has all the intentions of signing another striker apart from Vieri, and the most likely candidates are Cacia, Bjelanovic and Pellicori.
