Massara concedes there's been little recent movement.
He said, "There is no news because there is no real negotiation process. Ibrahimovic is evaluating his options, as are we, so we're all waiting."
Massara also rejected suggestions Krzysztof Piatek will be sold in January.
“We do not intend to put Piatek on the market. We have faith in Krzysztof, so does the coach, he is working for the team and we're sure he'll get back to scoring goals soon."
