Osvaldo Coloccini, currently a youth coach at San Lorenzo, believes a resolution must come quickly.
"Fabricio is very anxious, he wants a resolution," he explained. "I think that it's the moment for him to return to San Lorenzo. We want him to come back.
"In the last few hours, Newcastle have bought a defender but that means nothing because they were looking for an option in that position anyway.
"At Newcastle they are telling him to wait until May but the thing is that I don't know if San Lorenzo are going to be able to wait until then."
