Antonello is also coy over reports of a deal in place for Racing striker Lautero Martinez.
“Pastore was never an objective," he said. "Now is the time to focus on the game and not the transfer market. A victory would give back confidence and allow us to resume our march towards the Champions League."
On Matinez, Antonello added: “Our work continues day by day, as we are always looking out for talents around the world."
